Abstract
Description
- This invention relates to an set of sectional elements arranged to form a series of filters for filtering the feed air to the internal combustion engine of an industrial vehicle.
- With the set of elements of the invention it is possible, by changing certain elements of the set, to form filters suitable for use on vehicles having different dimensions and different engines. Different filters can be formed by merely mounting on certain basic elements of the unit other selectable elements which differ from each other only in terms of some dimension, but which can be connected to said basic elements without the need for any special adaptation.
- The sectional element set of the invention is characterised by comprising:
- a hollow shell defined by side walls, an upper wall and a lower wall, said shell having a first aperture in said side wall and a second and a third aperture in said lower and upper wall respectively;
- a series of socket-shaped bodies each of which has a predetermined height which is different from that of the other and is arranged to be selectively fixed to said hollow shell to close said second aperture and to house, together with said hollow shell, an annular shaped air filter element of predetermined height;
- a series of covers each of which is provided with a tubular connector of diameter different from the others, and is arranged to be selectively fixed to said shell to close said third aperture and to be connected to a corresponding pipe for feeding air to the air manifold of said engine;
- a cup-shaped element to be fixed to said hollow shell in order to close said first aperture and to define an air chamber therewith, said cup-shaped element having a height greater than that of said third aperture so that when it is mounted on said hollow shell it defines an air inlet port;
- a series of air entry connector elements, each of which is arranged to be fixed selectively to said air inlet port to define an air entry connector of different dimensions from the others. The invention will be more apparent from the detailed description of one embodiment thereof given hereinafter by way of example with reference to the accompanying drawings in which:
- Figure 1 is a side view of the sectional elements which form part of the element set according to the invention;
- Figure 2 is a partly sectional side view of a filter obtained from the element set of the invention;
- Figure 3 is a plan view of the filter of the preceding figure.
- The set of sectional elements of the invention comprises substantially a pair of basic sectional elements indicated by 1 and 2 and three different series of sectional elements of slightly different dimensions and arranged to be fixed selectively to the two aforesaid basic elements; the sectional elements of the three said series are indicated overall by 3, 4 and 5.
- The
basic element 1 is substantially a hollow shell defined byside walls 6, an upper wall 7 and a lower wall 8. Said walls comprise apertures indicated respectively by 9, 10 and 11, and visible in Figure 1. The other basic element, indicated by 2, is substantially cup-shaped and is arranged to be fixed to thehollow shell 1 to close the aperture 9 and define therewith anair chamber 13. Said element has a height greater than that of the aperture 9 so that when it is mounted on the hollow shell it defines an air inlet port indicated by 14. Conveniently, thehollow shell 1 is provided with anannular flange 15 against which there rests acorresponding flange 16 of the cup-shaped element 2, as shown in Figure 1. Each of the twobasic elements - The sectional elements of the series of elements indicated by 3 are substantially socket-
shaped bodies hollow shell 1 to close theaperture 11 and to house, together with said hollow shell, an annular-shaped air filter of predetermined height. Said filter, indicated by 19, is shown in Figure 2 in which the various sectional elements of the set have been used to form a filter of required dimensions. Each of the socket-shaped bodies hollow shell 1 conveniently by anaxial tie bolt 20 passing through a hole in the body. - Conveniently, the upper edge of each of the socket-
shaped bodies corresponding aperture 11, and for this purpose can have itsedge 22 provided with ashoulder 23. - The sectional elements of the series indicated by 4 are substantially covers 24, each of which is provided with a
tubular connector 24 of diameter different from the other and is arranged to be selectively fixed to thehollow shell 1 to close the aperture 10 provided in the upper wall 7. Theconnector 25 is arranged to be connected to a corresponding pipe (not shown) which feeds air to the engine air manifold. Each of the covers is provided with anedge 26 having anannular groove 27 arranged to cooperate with the annular edge of the aperture 10. - The sectional elements of the series indicated by 5 are actual air entry connector elements and each of them is arranged to be selectively fixed to the
inlet port 14. The shape of each of said connector elements can be slightly different: that of the element shown highest in Figure 1 comprises substantially threeflat surfaces 28 defining an air inlet channel; in contrast, the other two elements have an assembly of walls defining achamber 29 and apipe stub 30 arranged to be connected to an air intake pipe, conveniently to the pipe of a dynamic air intake device the inlet mouth of which is located in known manner above the vehicle cab. - Each of said elements is provided with a
flange 31 arranged to be connected to theflange 15 of thehollow shell 1. The two elements which are lowest in Figure 1 are arranged to be fixed to the hollow shell such that the axis of thepipe stub 30 is horizontal (element in centre) or vertical (element below). - The set of sectional elements of the invention is used to form a filter suitable for a particular application in the following manner.
- A unit is firstly formed consisting of the two
basic elements series 3, 4 and 5 are then fixed to this unit. The element of the series 3 is selected to enable afilter element 19 of a predetermined height to be housed inside the filter. The element of the series 4 is selected according to the defined air throughput to be fed to the engine intake manifold, theconnectors 25 of the elements of this series having different diameters as stated. The element of theseries 5 is selected to adapt the filter to either a static air intake (using the element shown highest in Figure 1) or a dynamic air intake having its inlet into the filter on a horizontal axis or on a vertical axis (using one of the other two elements of the series). - A filter obtained in this manner is shown in Figures 2 and 3. It is apparent that modifications can be made to the present invention but without leaving its scope. In particular, although
series 3, 4 and 5 are shown comprising only a few elements, each of these series can comprise a larger number of elements.
