DISPOSIÇÃO CONSTRUTIVA EM CONJUNTO DE TAMPA.DE FILTRO DE COMBUSTÍVEL CONSTRUCTIVE ARRANGEMENT OF FUEL FILTER COVER.
CAMPO DA INVENÇÃO FIELD OF INVENTION
A presente invenção refere-se a uma tampa. Mais especificamente, a presente invenção refere-se a uma tampa de filtro, particularmente um filtro de combustível de um veículo automotor, dotada de uma disposição construtiva capaz de facilitar o seu fechamento ou abertura quando da manutenção do dito filtro. The present invention relates to a lid. More specifically, the present invention relates to a filter cover, particularly a fuel filter of a motor vehicle, provided with a constructive arrangement capable of facilitating its closing or opening when maintaining said filter.
A presente invenção refere-se também a um conjunto de tampa e carcaça. Mais especificamente, a presente invenção refere-se também a um conjunto de tampa e carcaça, particularmente para filtros de combustíveis de veículos automotores, configurado para impedir ou ao menos reduzir a incidência de fechamento incompleto entre estas duas peças. The present invention also relates to a lid and housing assembly. More specifically, the present invention also relates to a lid and housing assembly, particularly for automotive fuel filters, configured to prevent or at least reduce the incidence of incomplete closure between these two parts.
ANTECEDENTES DA INVENÇÃO BACKGROUND OF THE INVENTION
O sistema de alimentação de combustível de um veículo automotor tem a função de permitir a condução do combustível do tanque até a câmara de combustão, com uma pressão substancialmente constante. The fuel supply system of a motor vehicle has the function of allowing fuel to be driven from the tank to the combustion chamber at substantially constant pressure.
Normalmente, tal sistema compreende uma bomba de alimentação, um filtro de combustível, um tubo distribuidor, um regulador de pressão e válvulas de injeção. Em operação, a bomba alimentadora possibilita o transporte do combustível do tanque para o tubo distribuidor, passando pela linha de combustível. Já a válvula reguladora de pressão controla a pressão na dita linha. Neste trajeto, o combustível passa também por um filtro, posicionado em qualquer ponto entre a bomba do combustível e as válvulas de injeção, que será detalhado a seguir. Typically, such a system comprises a feed pump, a fuel filter, a manifold, a pressure regulator and injection valves. In operation, the feeder pump makes it possible to transport fuel from the tank to the manifold through the fuel line. The pressure regulating valve controls the pressure in said line. In this route, the fuel also passes through a filter, positioned anywhere between the fuel pump and the injection valves, which will be detailed below.
Como já é de conhecimento do estado da técnica, os filtros consistem em meios capazes de permitir o fluxo de uma substância necessária, tal como o fluido combustível e, ao mesmo tempo, obstruir a passagem de substâncias indesejáveis, como, por exemplo, partículas sólidas ou líquidas.
Particularmente com relação a um filtro de combustível, este tem a finalidade de reter impurezas contidas no combustível por meio de um elemento filtrante, tal como um papel, envolvido por uma carcaça constituída normalmente de nylon, aço, alumínio ou plástico. As is well known in the art, filters consist of means capable of permitting the flow of a necessary substance such as combustible fluid and at the same time blocking the passage of undesirable substances such as solid particles. or liquid. Particularly with respect to a fuel filter, it is intended to retain impurities contained in the fuel by means of a filter element, such as paper, surrounded by a housing normally made of nylon, steel, aluminum or plastic.
Em outras palavras, os filtros de combustível protegem o sistema de alimentação do combustível, eliminando ou ao menos reduzindo as impurezas presentes no combustível, provenientes do transporte, estocagem e/ou do próprio tanque, o que evita a obstrução de orifícios das válvulas injetoras. Assim, os filtros proporcionam um melhor desempenho do motor e, consequentemente, um aumento de sua vida útil. In other words, fuel filters protect the fuel supply system by eliminating or at least reducing the impurities present in the fuel from transport, storage and / or the tank itself, preventing clogged nozzle orifices. Thus, the filters provide better engine performance and therefore an increased engine life.
Idealmente, o filtro deve proporcionar alta eficiência na retenção de contaminantes e, além disso, baixa resistência ao fluxo do combustível. Além disso, o filtro deve ser projetado de maneira a garantir boa vedação e alta resistência a pressões internas. Ideally, the filter should provide high contaminant retention efficiency and low fuel flow resistance. In addition, the filter must be designed to ensure good sealing and high resistance to internal pressures.
Atualmente, devido à alteração do sistema carburado para sistema de injeção eletrônico, o filtro passou a ser uma peça essencial, uma vez que as partículas indesejadas existentes no combustível podem causar um desgaste excessivo dos componentes do sistema de injeção. Today, due to the change from the carburized system to the electronic injection system, the filter has become an essential part as unwanted particles in the fuel can cause excessive wear on the injection system components.
Neste sentido, cumpre notar que a ausência do filtro seguramente causaria problemas na partida do motor e prejudicaria significativamente a dirigibilidade do veículo, causando um aumento do consumo de combustível e de desgaste dos componentes, não obstante possíveis falhas de funcionamento. In this regard, it should be noted that the absence of the filter would surely cause engine starting problems and significantly impair vehicle drivability, causing increased fuel consumption and component wear despite possible malfunctions.
Vale destacar que a vida útil do filtro depende da quantidade de impurezas contidas no combustível e varia de acordo com a quilometragem indicada para cada modelo/tipo de veículo. De todo modo, a troca do filtro deve ser feita periodicamente em manutenções preventivas. Note that the filter life depends on the amount of impurities contained in the fuel and varies according to the indicated mileage for each model / type of vehicle. In any case, the filter must be changed periodically for preventive maintenance.
Nestas manutenções, o filtro é normalmente descartado
integralmente quando do fim de sua vida útil, uma vez que não é possível separar o elemento filtrante da carcaça para a sua substituição, pois o filtro consiste em uma peça que compreende uma carcaça permanentemente fechada, com o elemento filtrante já montado em seu interior. Naturalmente, este procedimento não é o mais adequado do ponto de vista ambiental/ecológico, uma vez que o material da carcaça não é usualmente biodegradável. Além do mais, uma vez que o filtro de combustível é realizado em materiais distintos, quais sejam, o material da carcaça e o material do elemento filtrante, por se tratar de uma peça única, fica difícil ou até mesmo impossível separar estes materiais para uma destinação adequada de descarte que seja ambientalmente sustentável. During these maintenances, the filter is normally discarded. entirely at the end of its useful life, as it is not possible to separate the filter element from the housing for replacement, since the filter consists of a part comprising a permanently enclosed housing, with the filter element already mounted inside it. Of course, this is not the most environmentally / environmentally sound procedure as the carcass material is not usually biodegradable. Moreover, since the fuel filter is made of different materials, namely the shell material and the filter element material, as they are a single piece, it is difficult or even impossible to separate these materials into one. proper disposal destination that is environmentally sustainable.
No sentido de solucionar este problema, a depositante do presente pedido de patente apresentou na publicação WO 2012/083405 um filtro de combustível cujo elemento filtrante pode ser separado da carcaça. Este filtro é dotado de uma tampa destacável em relação à carcaça, permitindo a substituição do elemento filtrante sem a necessidade de descartar a carcaça e também sem a necessidade de desconectar o filtro da linha de combustível. In order to solve this problem, the applicant of the present patent application has published in WO 2012/083405 a fuel filter whose filter element can be separated from the housing. This filter is provided with a detachable cover to the housing, allowing replacement of the filter element without the need to discard the housing and also without the need to disconnect the filter from the fuel line.
Entretanto, constatou-se que o filtro revelado no pedido de patente WO 2012/083405 possibilita que a tampa não seja fechada completamente em relação à carcaça por descuido do operador quando de sua manutenção, o que pode causar vazamentos indesejados, reduzindo o desempenho do sistema de alimentação, além do risco de incêndio devido à combustão desse combustível. Ainda, considerando que o filtro está integrado na linha de combustível, observa-se que, muitas vezes, o operador encontra certa dificuldade em rotacionar a tampa por completo (360° ou mais) quando de seu fechamento ou abertura. However, it has been found that the filter disclosed in patent application WO 2012/083405 enables the lid not to be completely closed to the casing due to operator negligence during maintenance, which may cause unwanted leaks, reducing system performance. as well as the risk of fire due to the combustion of this fuel. Also, considering that the filter is integrated in the fuel line, it is often observed that the operator finds it difficult to rotate the cap completely (360 ° or more) when it is closed or opened.
Em outras palavras, apesar do filtro objeto do pedido de patente WO 2012/083405 representar um avanço técnico significativo em relação aos
filtros de combustíveis comuns, ele ainda apresenta um potencial de aperfeiçoamento, principalmente no sentido de facilitar e auxiliar o operador a realizar a sua manipulação, reduzindo a incidência de possíveis erros de montagem, tal como o fechamento incompleto entre a tampa e a carcaça. In other words, although the filter object of patent application WO 2012/083405 represents a significant technical advance over common fuel filters, it still has potential for improvement, particularly in facilitating and assisting the operator in handling them, reducing the incidence of possible assembly errors, such as incomplete closure between the cover and the housing.
OBJETIVOS E DESCRIÇÃO DA INVENÇÃO OBJECTIVES AND DESCRIPTION OF THE INVENTION

De acordo com uma realização particular da invenção, e conforme
pode ser visto nas figuras 3, 5, 6 e 7, a carcaça 11 é provida de um conector de entrada 13 capaz de permitir a entrada de um fluido qualquer, preferencialmente um combustível. A carcaça 11 é capaz de abrigar um elemento filtrante (não ilustrado) adequado para o dito fluido, tal como um i papel filtrante. According to a particular embodiment of the invention, and according to As can be seen from Figures 3, 5, 6 and 7, the housing 11 is provided with an inlet connector 13 capable of allowing any fluid, preferably a fuel, to enter. The housing 11 is capable of housing a filter element (not shown) suitable for said fluid, such as a filter paper.
Por outro lado, a tampa 1 é provida de um conector de saída 3 capaz de permitir a saída do fluido filtrado pelo elemento filtrante, como pode ser observado nas figuras 1 , 2, 5, 6 e 7. On the other hand, the cap 1 is provided with an outlet connector 3 capable of allowing the filtered fluid to escape from the filter element, as can be seen from figures 1, 2, 5, 6 and 7.
Assim, a tampa 1 , a carcaça 11 e o elemento filtrante compõe, i particularmente, um filtro de combustível instalado em um sistema de alimentação de combustível por meio do conector de entrada 13 e pelo conector de saída 3. Thus, the lid 1, the housing 11 and the filter element particularly comprise a fuel filter installed in a fuel supply system by means of the inlet connector 13 and the outlet connector 3.
Conforme pode ser visto nas figuras 1 a 7, a tampa 1 e a carcaça 11 possuem um formato substancialmente cilíndrico. Mais especificamente, a tampa 1 compreende um corpo cilíndrico 2 dotado de uma extremidade superior 15, de formato substancialmente circular, e uma extremidade inferior 16, também de formato substancialmente circular e disposta paralelamente à extremidade superior 5, conforme pode ser observado nas figuras 1 e 2. As can be seen from figures 1 to 7, the lid 1 and the housing 11 have a substantially cylindrical shape. More specifically, the lid 1 comprises a cylindrical body 2 provided with a substantially circular shaped upper end 15 and a substantially circular shaped lower end 16 arranged parallel to the upper end 5 as can be seen from FIGS. 1 and 3. 2.
Ainda de acordo com as figuras 1 e 2, a tampa 1 compreende também uma superfície superior 4 configurada para fechar ao menos parcialmente a extremidade superior 15 do corpo cilíndrico 2. Particularmente, a superfície superior 4 e o corpo cilíndrico 2 formam uma peça única. Vale destacar que o conector de saída 3 se projeta a partir da superfície superior 4 para o exterior da tampa 1. Still according to figures 1 and 2, the lid 1 also comprises an upper surface 4 configured to at least partially close the upper end 15 of the cylindrical body 2. In particular, the upper surface 4 and the cylindrical body 2 form a single piece. It is noteworthy that the output connector 3 projects from the upper surface 4 to the outside of the lid 1.
Conforme pode ser visto nas figuras 1 a 7, o corpo cilíndrico 2 é provido de um primeiro rasgo 5 acessível e visível a um operador. Este primeiro rasgo 5 é disposto inclinadamente em relação à extremidade superior 15 do corpo cilíndrico 2.
Em outras palavras, o primeiro rasgo 5 possui uma projeção ortogonal disposta inclinadamente em relação a um eixo geométrico longitudinal x do dito conjunto da presente invenção. As can be seen from figures 1 to 7, the cylindrical body 2 is provided with a first slot 5 accessible and visible to an operator. This first slot 5 is arranged inclined with respect to the upper end 15 of the cylindrical body 2. In other words, the first slot 5 has an orthogonal projection inclined with respect to a longitudinal axis x of said assembly of the present invention.
Por outro lado, e de acordo com as figuras 3 a 7, a carcaça 11 compreende pelo menos um pino-guia 12 associável removivelmente ao primeiro rasgo 5. On the other hand, and according to Figures 3 to 7, the housing 11 comprises at least one guide pin 12 removably associable with the first slot 5.
Ainda de acordo com a figura 1 , o primeiro rasgo 5 da tampa 1 é delimitado por um subconjunto de batentes, quais sejam: Still according to figure 1, the first slot 5 of the lid 1 is delimited by a subset of stops, namely:
- um batente superior 6; - an upper stop 6;
- um batente inferior 7 disposto paralela e opostamente ao batente superior 6; a lower stop 7 disposed parallel and opposite to the upper stop 6;
- um primeiro batente lateral 8 disposto angularmente ao batente superior 6 e ao batente inferior 7, sendo que o primeiro batente lateral 8 associa o batente superior 6 ao batente inferior 7; e a first side stop 8 disposed angled to the upper stop 6 and the lower stop 7, the first side stop 8 associating the upper stop 6 to the lower stop 7; and
- um segundo batente lateral 9 disposto paralela e opostamente ao primeiro batente lateral 8, sendo que o segundo batente lateral 9 também associa o batente superior 6 ao batente inferior 7. a second side stop 9 disposed parallel and opposite to the first side stop 8, the second side stop 9 also associating the upper stop 6 with the lower stop 7.
O batente superior 6, o batente inferior 7, o primeiro batente lateral 8 e o segundo batente lateral 9 acima mencionados definem uma pista interna ao primeiro rasgo 5 na qual o pino-guia 12 é deslizável. Em outras palavras, o pino-guia 12 se movimenta na pista interna do primeiro rasgo 5 quando o operador abre ou fecha a tampa 1 em relação à carcaça 11. Particularmente, a pista interna delimitada pelos batentes caracteriza um formato geométrico de um paralelogramo ao primeiro rasgo 5. Naturalmente, outros formatos geométricos podem ser utilizados, desde que adequados à aplicação. The aforementioned upper stop 6, lower stop 7, first side stop 8 and second side stop 9 define an inner raceway to first slot 5 into which guide pin 12 is slidable. In other words, the guide pin 12 moves in the inner raceway of the first slot 5 when the operator opens or closes the lid 1 relative to the housing 11. In particular, the inner raceway delimited by the stops characterizes a geometric shape from a parallelogram to the first one. tear 5. Of course, other geometric shapes may be used, provided they are suitable for the application.
Conforme ilustrado nas figuras 3 e 4, a tampa 1 compreende ainda uma abertura auxiliar inferior 17 configurada para permitir a passagem do pino-guia 12 para a pista interna do primeiro rasgo 5 antes do operador iniciar o
movimento de fechamento entre a tampa 1 e a carcaça 11. Por outro lado, a abertura auxiliar inferior 17 também permite a passagem do pino-guia 12 da pista interna do primeiro rasgo 5 para fora da tampa 1 após o operador finalizarAs illustrated in Figures 3 and 4, the lid 1 further comprises a lower auxiliary opening 17 configured to allow the guide pin 12 to pass into the inner raceway of the first slot 5 before the operator begins the operation. closing movement between cover 1 and housing 11. On the other hand, the lower auxiliary opening 17 also allows guide pin 12 of the inner raceway of first slot 5 to exit cover 1 after the operator has finished
0 movimento de abertura entre a tampa 1 e a carcaça 11. The opening movement between the lid 1 and the housing 11.
As figuras 3, 5, 6 e 7, nesta ordem, mostram uma sequência de posições quando da operação de fechamento entre a tampa 1 e a carcaça 11. Em linhas gerais, o operador primeiramente encaixa o pino-guia 12 no primeiro rasgo 5 para depois aplicar um movimento rotacional na tampa 1 para fechar o conjunto. Tendo em vista o formato inclinado do primeiro rasgo 5, tal movimento rotacional proporciona também um movimento axial da tampa 1 em relação à carcaça 1 no sentido de fechamento. Naturalmente, a sequência contrária (figuras 7, 6, 5 e 3 nesta ordem) representa as posições da tampa 1 em relação à carcaça 1 quando da operação de abertura do conjunto. Figures 3, 5, 6 and 7, in this order, show a sequence of positions when closing between cover 1 and housing 11. In general, the operator first fits guide pin 12 into first slot 5 to then apply a rotational motion to cap 1 to close the assembly. In view of the inclined shape of the first slot 5, such rotational movement also provides an axial movement of the lid 1 with respect to the housing 1 in the closing direction. Naturally, the opposite sequence (figures 7, 6, 5 and 3 in this order) represents the positions of the lid 1 relative to the housing 1 when opening the assembly.
Particularmente, a figura 3 ilustra um arranjo em que o operador dispõe a tampa 1 em uma posição em que o pino-guia 12 fique alinhado com a abertura auxiliar inferior 17, para que o dito pino-guia 12 possa ser direcionado para a pista interna do primeiro rasgo 5 por aplicação de um movimento axial da tampa 1 em relação à carcaça 11. In particular, Figure 3 illustrates an arrangement in which the operator arranges the lid 1 in a position where the guide pin 12 is aligned with the lower auxiliary opening 17 so that said guide pin 12 can be directed to the inner raceway. first slot 5 by applying an axial movement of the lid 1 relative to the housing 11.
Na sequência, quando o movimento de fechamento entre a tampa Then when the closing movement between the lid
1 e a carcaça 11 se inicia (figura 5), o pino-guia 12 é posicionado adjacentemente ao primeiro batente lateral 8. A partir desta posição inicial, o operador deve rotacionar a tampa 1 para deslizar o pino-guia 12 na pista interna do primeiro rasgo 5 no único sentido possível. A figura 6 ilustra uma posição intermediária do pino-guia 12 na pista interna do primeiro rasgo 5. 1 and housing 11 begins (Figure 5), guide pin 12 is positioned adjacent to first side stop 8. From this initial position, the operator must rotate cover 1 to slide guide pin 12 into the inner raceway. first tear 5 in the only possible direction. Figure 6 illustrates an intermediate position of the guide pin 12 in the inner raceway of the first slot 5.
No final do movimento de fechamento entre a tampa 1 e a carcaça 11 , representado na figura 6, o pino-guia 12 é posicionado adjacentemente ao segundo batente lateral 8. At the end of the closing movement between the lid 1 and the housing 11 shown in FIG. 6, the guide pin 12 is positioned adjacent to the second side stop 8.
Ainda de maneira particular, o primeiro rasgo 5 possui um
comprimento total que consiste na extensão da semicircunferência do corpo cilíndrico 2, de modo a permitir o movimento do pino-guia 12 na pista interna do primeiro rasgo 5 entre zero e 180 graus geométricos. Tal configuração facilita bastante o movimento de abertura ou fechamento pelo operador, uma vez que ele não precisa mais realizar rotações de, por exemplo, 360 graus geométricos ou mais, em um espaço, muitas vezes limitado (apertado). Opcionalmente, o primeiro rasgo 5 pode assumir um comprimento maior ou menor que a extensão da semicircunferência. Still in particular, the first slot 5 has a total length consisting of the semi-circumference extension of the cylindrical body 2 so as to allow the guide pin 12 to move in the inner race of the first slot 5 between zero and 180 degrees. Such a configuration greatly facilitates the operator's opening or closing movement as he no longer has to rotate, for example, 360 degrees or more, in a often limited (tight) space. Optionally, the first slot 5 may be longer or shorter than the length of the semicircle.
Preferencialmente, mas não obrigatoriamente, o conjunto da invenção compreende um subconjunto de travamento configurado para permitir a fixação da tampa 1 na carcaça 11 após o fechamento destas partes. Tal subconjunto de travamento é dotado de um gancho inferior 14 compreendido pela tampa 1 , conforme pode ser visto nas figuras 1 , 2, 5, 6 e 7. O gancho inferior 14 é configurado para permitir a limitação do movimento de abertura ou fechamento da tampa 1. O subconjunto de travamento é dotado também de um elemento de apoio 10 compreendido pela carcaça 11 , como pode ser visto nas figuras 5 a 7. O elemento de apoio 10 é associado ao gancho inferior 14 quando do fechamento da tampa 1 na carcaça 11 (figura 7). Preferably, but not necessarily, the assembly of the invention comprises a locking subassembly configured to allow the cap 1 to be secured to the housing 11 upon closing of these parts. Such a locking subassembly is provided with a lower hook 14 comprised of the lid 1, as can be seen from figures 1, 2, 5, 6 and 7. The lower hook 14 is configured to limit the opening or closing movement of the lid. 1. The locking subassembly is also provided with a support element 10 comprised of the housing 11, as can be seen from figures 5 to 7. The support element 10 is associated with the lower hook 14 when closing the lid 1 on the housing 11 (figure 7).
De maneira particular, a tampa 1 compreende ainda um segundo rasgo 18 disposto diametralmente oposto ao primeiro rasgo 5, como mostrado na figura 2. Por outro lado, a carcaça 11 compreende um segundo pino-guia associável removivelmente ao segundo rasgo 18. O segundo rasgo 18 e o segundo pino-guia apresentam as mesmas características do primeiro rasgo 5 e do pino-guia 12 descrito acima, respectivamente, e estes elementos proporcionam uma maior segurança no fechamento da tampa 1 na carcaça 11. In particular, the lid 1 further comprises a second slot 18 disposed diametrically opposite the first slot 5, as shown in Figure 2. On the other hand, the housing 11 comprises a second guide pin removably associable with the second slot 18. The second slot 18 and the second guide pin have the same characteristics as the first slot 5 and guide pin 12 described above, respectively, and these elements provide greater security in closing the lid 1 on the housing 11.
No tocante ao material, a tampa 1 e a carcaça 11 são constituídas de plástico. Opcionalmente, a tampa 1 e a carcaça 11 podem ser constituídas de outros tipos de materiais, tais como nylon, aço e alumínio.
Assim, o conjunto formado pela tampa 1 e carcaça 11 da invenção apresenta uma maior simplicidade, facilidade e rapidez de fechamento e abertura quando da montagem ou desmontagem do filtro, respectivamente, com relação aos conjuntos do estado da técnica, uma vez que o primeiro rasgo 5 e o pino-guia 12 estão sempre acessíveis e visíveis ao operador, orientando-o e o auxiliando-o na execução do movimento de fechamento ou abertura, de modo a eliminar ou ao menos reduzir a ocorrência de possíveis erros de montagem, tal como o fechamento incompleto entre a tampa 1 e a carcaça 11. As regards the material, the lid 1 and the housing 11 are made of plastic. Optionally, the lid 1 and the housing 11 may be made of other types of materials, such as nylon, steel and aluminum. Thus, the assembly formed by the lid 1 and housing 11 of the invention has a greater simplicity, ease and speed of closing and opening when assembling or disassembling the filter, respectively, in relation to the prior art assemblies, since the first tear 5 and guide pin 12 are always accessible and visible to the operator, guiding and assisting him in performing the closing or opening movement so as to eliminate or at least reduce possible mounting errors such as incomplete closing between cover 1 and housing 11.
Em outras palavras, a presente invenção permite que manutenção do filtro (ex: troca do papel filtrante do filtro) possa ser feita de uma maneira fácil, simples e rápida, sem que haja risco de fechamento incompleto entre a tampa e carcaça. In other words, the present invention allows filter maintenance (eg changing filter paper) to be performed easily, simply and quickly without risk of incomplete closure between the lid and the housing.
Em uma realização alternativa da invenção, ilustrada nas figuras 8 e 9, o conjunto compreende pelo menos um clipe de reforço 19 configurado para travar fixamente a tampa 1 à carcaça 11. Naturalmente, o clipe de reforço 19 permite também o destravamento da tampa 1 da carcaça quando da manutenção do filtro. In an alternative embodiment of the invention, illustrated in Figures 8 and 9, the assembly comprises at least one reinforcement clip 19 configured to lock the lid 1 to the housing 11. Of course, the reinforcement clip 19 also allows the unlocking of the lid 1 of the housing. housing when maintaining the filter.
Particularmente, o clipe de reforço 19 está distanciado 90° em relação ao pino-guia 12, como pode ser visto na figura 8, de modo a proporcionar maior robustez e segurança em aplicações mais pesadas. In particular, the reinforcing clip 19 is 90 ° spaced from the guide pin 12, as can be seen in figure 8, to provide greater robustness and safety in heavier applications.
Outra função do clipe de reforço 19 é facilitar a montagem e desmontagem do filtro para a substituição do papel filtrante.
