Description

Die Erfindung betrifft eine Vorrichtung zum Regeln einer Durchströmung eines Kanals mit einem Fluid, insbesondere mit Luft, wobei ein Querschnitt des Kanals durch ein sich in dem Kanal bewegendes Element mittels einer Stelleinrichtung auf einer Aufspannplatte veränderbar ist.The invention relates to a device for regulating a flow through a channel with a fluid, in particular with air, wherein a cross section of the channel is variable by a moving element in the channel by means of an adjusting device on a platen.

Stand der TechnikState of the art

Eine derartige Vorrichtung ist beispielsweise aus der EP 0 615 102 A1 bekannt. Dort ist in einem Rohrabschnitt eine um eine Drehachse drehbar gelagerte Drosselklappe angeordnet. Dieser Drehachse ist ein Kraftspeicher zugeordnet. Die Drosselklappe bewegt sich gegen einen Luftstrom in Öffnungslage. Dabei ist der Drehachse eine Einrichtung zugeordnet, welche die Drosselklappe gegen die Kraft des Kraftspeichers verschliesst.Such a device is for example from the EP 0 615 102 A1 known. There, a throttle flap rotatably mounted about a rotation axis is arranged in a pipe section. This axis of rotation is associated with a force storage. The throttle valve moves against an air flow in the open position. In this case, the rotation axis is associated with a device which closes the throttle valve against the force of the force accumulator.

Eine ähnliche Einrichtung ist auch aus der G 92 08 345.5, der DE 32 27 882 A1 und der DE 14 901 bekannt.A similar device is also from the G 92 08 345.5, the DE 32 27 882 A1 and the DE 14 901 known.

Aufgabetask

Aufgabe der vorliegenden Erfindung ist es, eine o.g. Vorrichtung zu entwickeln, deren Einstellung auf einen sich verändernden Luftstrom wesentlich verbessert ist, bei der vor allem die Feinfühligkeit des Ansprechverhaltens wesentlich erhöht ist.Object of the present invention is an o.g. To develop device whose adjustment is significantly improved to a changing air flow, in which especially the sensitivity of the response is substantially increased.

Lösung der AufgabeSolution of the task

Zur Lösung der Aufgabe führt, dass dem sich in dem Kanal bewegenden Element ein Bügel zugeordnet ist, der einends mit dem sich in dem Kanal bewegenden Element und anderenends über einen Kraftspeicher mit einem Anlenkelement auf der Aufspannplatte verbunden ist, wobei sich der Bügel zwischen den beiden Verbindungen abstützt.To achieve the object, that the element moving in the channel is associated with a bracket which is connected at one end to the moving element in the channel and the other end via a power storage with a hinge element on the platen, wherein the bracket between the two Supports connections.

Diese erfindungsgemässe Anordnung hat den grossen Vorteil, dass die Einstellung auf mehrere Arten erfolgen kann, die in günstiger Weise aufeinander abgestimmt werden können. Eine Einstellung übernimmt der Kraftspeicher. Dieser kann z.B. ein Gummizug od. dgl. sein, bevorzugt wird wohl eine Schraubenfeder. Dieser Kraftspeicher gewährleistet, dass der Bügel immer wieder in seine gewünschte Ausgangslage zurückgebracht wird bzw. einem sich ändernden Luftstrom und damit einer Kraft, die auf das sich im Kanal bewegende Element einwirkt, eine Gegenkraft entgegensetzt wird. Je höher die auf das sich im Kanal bewegende Element wirkende Kraft ist, umso grösser sollte auch die entgegenwirkende Kraft durch den Kraftspeicher sein. Aus diesem Grunde ist die Spannung des Kraftspeichers einstellbar. Dazu ist der Kraftspeicher einends mit dem Bügel und andernends mit einem Anlenkelement verbunden. Dieses Anlenkelement kann beliebige ausgestaltet sein, in einem bevorzugten Ausführungsbeispiel handelt es sich um einen Bolzen.This inventive arrangement has the great advantage that the adjustment can be made in several ways that can be matched in a favorable manner to each other. A setting takes over the energy storage. This can be, for example, an elastic band or the like, preferably a helical spring. This energy storage ensures that the bracket is always returned to its desired starting position or a changing air flow and thus a force acting on the moving element in the channel, an opposing force is opposed. The higher the force acting on the channel moving element, the greater should be the counteracting force through the energy storage. For this reason, the voltage of the energy storage is adjustable. For this purpose, the energy storage is at one end connected to the bracket and the other end with a hinge element. This articulation element can be configured as desired, in a preferred embodiment it is a Bolt.

Auch der Begriff der Aufspannplatte ist sehr weit zu sehen. Darunter sind alle Halterungen zu verstehen, welche die Stelleinrichtung bzw. Teile dieser Stelleinrichtung gegenüber dem Kanal bzw. gegenüber dem sich in dem Kanal bewegenden Element festlegen.Also the term of the clamping plate is to be seen very far. This is to be understood as meaning all holders which fix the adjusting device or parts of this adjusting device relative to the channel or to the element moving in the channel.

Die Einstellung des Kraftspeichers könnte nun der Einfachheit halber dadurch geschehen, dass der Anlenkbolzen auf der Aufspannplatte ortsveränderbar angeordnet ist. Hier bietet sich beispielsweise ein entsprechender Schieber an, der entlang der Aufspannplatte verschoben werden kann. Auch für das Verschieben des Schiebers sind viele Möglichkeiten denkbar, die von der vorliegenden Erfindung erfasst sein sollen.The adjustment of the energy storage could now be done for the sake of simplicity, that the pivot pin is arranged on the platen movable. Here, for example, offers a corresponding slider, which can be moved along the platen. Also for the displacement of the slide many possibilities are conceivable that should be covered by the present invention.

In einem verbesserten Ausführungsbeispiel ist aber ein Exzenter angeordnet, der den Bügel etwa mittig angreift. Der Bügel liegt auf diesem Exzenter exzentrisch an, so dass der Bügel bei Drehung des Exzenter geschwenkt werden kann und damit die Spannung des Kraftspeichers beeinflusst wird. Dies ist eine sehr elegante Lösung, da im Gegensatz zur Lageveränderung eines Schiebers das Drehen des Exzenters von aussen auf einfache Art und Weise erfolgen kann. In diesem letzt genannten Fall ist der Schieber eigentlich weniger zu einer Veränderung der Spannung des Kraftspeichers gedacht, sondern zu einer insgesamten Lageveränderung der Stelleinrichtung für den Bügel gegenüber der Drehachse des sich in dem Kanal bewegenden Elements.In an improved embodiment, however, an eccentric is arranged, which attacks the bracket approximately centrally. The bracket is eccentric on this eccentric, so that the bracket can be pivoted upon rotation of the eccentric and thus the voltage of the force accumulator is affected. This is a very elegant solution, since in contrast to the change in position of a slider, the rotation of the eccentric can be done from the outside in a simple manner. In this latter case, the slider is actually intended less to a change in the voltage of the energy storage, but to an overall change in position of the adjusting device for the bracket relative to the axis of rotation of the moving element in the channel.

Wenn in der vorliegenden Erfindung von Exzenter gesprochen wird, so sollen hier alle Möglichkeiten erfasst sein, die gewährleisten, dass der Bügel mehr oder weniger gegenüber seiner mittigen Abstützung schwenkt.Whenever eccentrics are used in the present invention, it is intended to encompass all possibilities which ensure that the stirrup pivots more or less in relation to its central support.

Andernends der Verbindung mit dem Kraftspeicher ist der Bügel über eine Schubstange mit einem Rad verbunden, das wiederum dem sich in dem Kanal bewegenden Element zugeordnet ist. In der Regel, aber nicht ausschliesslich, handelt es sich bei dem sich in dem Kanal bewegenden Element um eine Klappe, welche im Öffnungsquerschnitt den Kanal mehr oder weniger verschliesst. Meist dreht diese Klappe um eine Drehachse. In diesem Fall ist das Rad der Drehachse aufgesetzt, so dass über das Rad und die Schubstange eine Zug- bzw. Druckkraft auf den Bügel aufgebracht wird. Durch dieses Rad wird aber auch eine Grundeinstellung des sich in dem Kanal bewegenden Elements durchgeführt. Hierzu ist dem Rad ein weiteres Drehelement zugeordnet, welches in einem bevorzugten Ausführungsbeispiel mit einer entsprechenden Zahnung in eine entsprechende Gegenzahnung in oder an dem Rad angreift. Über dieses Drehelement wird eine Grundeinstellung des Rades und damit der Klappe erzeugt.At the other end of the connection with the energy storage, the bracket is connected via a push rod with a wheel, which in turn is assigned to the moving element in the channel. Usually, but not exclusively, If the element moving in the channel is a flap which closes the channel more or less in the opening cross-section. Mostly this flap rotates about a rotation axis. In this case, the wheel of the rotation axis is placed so that a tensile or compressive force is applied to the bracket via the wheel and the push rod. By this wheel but also a basic adjustment of the moving in the channel element is performed. For this purpose, the wheel is associated with a further rotary element, which engages in a preferred embodiment with a corresponding toothing in a corresponding counter toothing in or on the wheel. About this rotary element a basic setting of the wheel and thus the flap is generated.

Figurenbeschreibungfigure description

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt in ihrer einzigen Figur eine perspektivische Ansicht einer erfindungsgemässen Vorrichtung zum Regeln einer Durchströmung eines Kanals 1 mit einem Fluid. Die Regelung dieser Durchströmung übernimmt eine Klappe 2, die in dem Kanal 1 angeordnet ist und um eine Drehachse 3 drehen kann.Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing; This shows in its single figure a perspective view of an inventive device for controlling a flow through a channel 1 with a fluid. The regulation of this flow takes over a flap 2, which is arranged in the channel 1 and can rotate about a rotation axis 3.

Einem Gewinde 4 dieser Drehachse 3 ist ein Rad 5 aufgesetzt, welches mit einem Drehelement 6 in Wirkverbindung steht. Hierzu besitzt das Drehelement 6 eine Zahnung 7, die, in der Zeichnung nicht näher gezeigt, mit einer entsprechenden, dem Rad 5 zugeordneten Zahnung in Eingriff steht. Das Drehelement 6 und die Verbindung zum Rad 5 ist so ausgelegt, dass das Rad 5 in einem gewissen Winkelbereich um die Drehachse 3 gedreht werden kann.A thread 4 of this axis of rotation 3, a wheel 5 is placed, which is in operative connection with a rotary member 6. For this purpose, the rotary member 6 has a toothing 7, which, not shown in detail in the drawing, with a corresponding, the wheel 5 associated toothing is engaged. The rotary member 6 and the connection to the wheel 5 is designed so that the wheel 5 can be rotated in a certain angular range about the rotation axis 3.

Das Drehelement 6 selbst sitzt auf einer Aufspannplatte 8 auf, die wiederum über entsprechende Verbindungselement 9 mit dem Kanal 1 verbunden ist. Im vorliegenden Ausführungsbeispiel ist das Drehelement 6 als ein Kreissegment ausgebildet, welches um eine Drehachse 10 drehen kann. Zum Zwecke der besseren Montage kann es in gewissem Umfang auf der Aufspannplatte 8 verschiebbar angeordnet sein. Dies ist aber für die Erfindung von untergeordneter Bedeutung.The rotary element 6 itself sits on a clamping plate 8, which in turn is connected via corresponding connecting element 9 with the channel 1. In the present embodiment, the rotary member 6 is formed as a circular segment which can rotate about a rotation axis 10. For the purpose of better mounting, it may be arranged to a certain extent slidably on the platen 8. However, this is of minor importance to the invention.

Das Rad 5 wiederum ist mit einem Bügel 11 an dessen einen Ende verbunden. Zur Verbindung ist eine Schubstange 12 vorgesehen, die im vorliegenden Ausführungsbeispiel S-förmig gekrümmt ist und mit ihren jeweiligen gekrümmten Enden 13.1 und 13.2 ein exzentrisch angeordnete Bohrung 14 in dem Rad 5 und ein Loch 15 in dem Bügel 11 durchdringt. Dem Loch 15 sind weitere Löcher zugeordnet, wodurch eine Position der Schubstange 12 gegenüber dem Bügel 11 verändert werden kann.The wheel 5 in turn is connected to a bracket 11 at one end. To connect a push rod 12 is provided, which is curved in the present embodiment S-shaped and with their respective curved ends 13.1 and 13.2 an eccentrically arranged bore 14 in the wheel 5 and a hole 15 in the bracket 11 penetrates. The hole 15 further holes are assigned, whereby a position of the push rod 12 relative to the bracket 11 can be changed.

Etwa mittig stützt sich der Bügel 11 gegen einen Exzenter 16 ab, der wiederum gegenüber einer zungenförmigen Halterung 17 drehbar angeordnet ist. Der Übersichtlichkeit halber ist eine entsprechende Drehachse nicht gezeigt, die Drehrichtung ist lediglich durch den Doppelpfeil 18 angedeutet.Approximately in the middle, the bracket 11 is supported against an eccentric 16, which in turn is arranged rotatable relative to a tongue-shaped holder 17. For clarity, a corresponding axis of rotation is not shown, the direction of rotation is indicated only by the double arrow 18.

Der Bügel 11 stützt sich an dem Exzenter 16 so ab, dass er quasi um den Exzenter in einem gewissen Umfang schwenken kann. Dies soll durch die Pfeile 19.1 und 19.2 dargestellt sein.The bracket 11 is supported on the eccentric 16 so that it can pivot about the eccentric to a certain extent. This should be represented by the arrows 19.1 and 19.2.

Die Halterung 17 ist mit einem Schieber 20 verbunden, welcher auf der Aufspannplatte 8 gleitbar angeordnet ist. Geführt wird der Schieber 20 dabei durch entsprechende Bolzen 21.1 und 21.2, die in ein Langloch 22 in der Aufspannplatte 8 eingreifen.The holder 17 is connected to a slider 20 which is slidably mounted on the platen 8. The slider 20 is guided by corresponding bolts 21.1 and 21.2, which engage in a slot 22 in the clamping plate 8.

Von dem Schieber 20 ragt auch ein Bolzen 23 auf, der ein Anlenkelement für einen Kraftspeicher 24 darstellt. Dieser Kraftspeicher 24 kann eine Schraubenfeder sein. Er ist einerseits mit dem Bolzen 23 und andererseits mit einem weiteren Ende 25 des Bügels 11 verbunden.From the slide 20 also projects a bolt 23, which constitutes a hinge element for a force accumulator 24. This energy storage 24 may be a coil spring. He is on the one hand connected to the bolt 23 and on the other hand with a further end 25 of the bracket 11.

Die Funktionsweise der vorliegenden Erfindung ist folgende:The operation of the present invention is as follows:

Zur anfänglichen Einstellung der Öffnungslage der Klappe 2 in dem Kanal 1 wird über das Drehelement 6 das Rad 5 bewegt. Hierdurch kann ein vom Kunden gewünschter Volumenstrom oder ein werksseitig vorgegebener Referenzvolumenstrom eingestellt werden.For initial adjustment of the opening position of the flap 2 in the channel 1, the wheel 5 is moved via the rotary member 6. As a result, a desired by the customer flow or a factory-set reference volume flow can be adjusted.

Um aber seiner Aufgabe gerecht zu werden, nämlich in einem komplexen Rohrleitungssystem eine selbsttätige Regelung der Luftmengenverteilung vorzunehmen, kann diese Einstellung nicht fixiert sein, sondern es muss die Möglichkeit bestehen, dass je nach Luftmenge das Rad 5 um die Drehachse 3 drehbar ist, damit die Klappe 2 mehr oder weniger den Querschnitt des Rohrs 1 verschliessen kann. Hierzu sind Regelungselemente vorgesehen. Dazu gehört vor allem der Bügel 11, der einerseits über die Schubstange 12 in seinem Abstand zum Rad 5 relativ fixiert ist. Dieser Abstand kann allerdings durch Einsetzen des Schubstange 12 in die unterschiedlich positionierten Löcher 15 am Ende des Bügels 11 verändert werden.However, in order to do justice to its task, namely to carry out an automatic regulation of the air volume distribution in a complex piping system, this setting can not be fixed, but there must be the possibility that, depending on the amount of air, the wheel 5 is rotatable about the axis of rotation 3, so that the Flap 2 can more or less close the cross section of the tube 1. For this purpose, control elements are provided. This includes especially the bracket 11, which is relatively fixed on the one hand via the push rod 12 in its distance from the wheel 5. However, this distance can be changed by inserting the push rod 12 in the differently positioned holes 15 at the end of the bracket 11.

Der Kraftspeicher 24, der den Bügel 11 am anderen Ende angreift, wirkt einem von der Luftströmung auf das Klappenblatt 2 aufgebrachten Druck entgegen. Dabei schwenkt der Bügel 11 um den Exzenter 16, wobei dies sogar mehr ein Vibrieren sein kann.The energy storage 24, which engages the bracket 11 at the other end, counteracts a pressure applied by the air flow to the damper blade 2 pressure. In this case, the bracket 11 pivots about the eccentric 16, and this may even be more a vibration.

Der Exzenter 16 hat die Aufgabe, wenn er gegenüber der Halterung 17 gedreht wird, den Bügel 11 beispielsweise in Richtung der Pfeile 19.1 und 19.2 zu bewegen bzw. einem entsprechenden Druck des Bügels 11 nachzugeben, wobei der Kraftspeicher 24 in diesem Fall mehr entspannt wird. Damit wird aber auch der Klappe 2 die Möglichkeit gegeben, sich leichter um die Drehachse 3 drehen zu können.The eccentric 16 has the task when it is rotated relative to the holder 17 to move the bracket 11, for example, in the direction of the arrows 19.1 and 19.2 and give in to a corresponding pressure of the bracket 11, the energy storage 24 is more relaxed in this case. But also the flap 2 is given the opportunity to turn around the axis of rotation 3 easier.

Insgesamt kann die Anordnung aus Exzenter, Bügel, Halterung, Kraftspeicher 24 und Bolzen 23 gegenüber der Drehachse 3 der Klappe 2 durch Verschieben des Schiebers 20 verstellt werden. Dies verbessert nochmals die Feinfühligkeit des Ansprechverhaltens der Klappe 2 auf einen sich ändernden Luftstrom.
