Definitions

  • This invention relates to a 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.
  • An air cleaner wherein povision is made for connecting said cleaner to air intake types of various sizes and dimensions is known from document US-A-2 480 379.
  • 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 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 by side 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 the hollow shell 1 to close the aperture 9 and define therewith an air 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.
  • the hollow shell 1 is provided with an annular flange 15 against which there rests a corresponding flange 16 of the cup-shaped element 2, as shown in Figure 1.
  • Each of the two basic elements 1 and 2 is conveniently constructed of thermoplastic material using the normal forming methods for such material. Said two elements can be joined together to form the unit shown in figure 1 by any suitable method, for example by welding, gluing or the like.
  • the sectional elements of the series of elements indicated by 3 are substantially socket-shaped bodies 17 and 18, each of which has a predetermined height which is different from the height of the other and is arranged to be fixed selectively to the hollow shell 1 to close the aperture 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 17 and 18 is fixed to the hollow shell 1 conveniently by an axial tie bolt 20 passing through a hole in the body.
  • each of the socket-shaped bodies 17, 18 is suitably shaped to be able to be housed in the corresponding aperture 11, and for this purpose can have its edge 22 provided with a shoulder 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 the hollow shell 1 to close the aperture 10 provided in the upper wall 7.
  • the connector 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 an edge 26 having an annular 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 three flat surfaces 28 defining an air inlet channel; in contrast, the other two elements have an assembly of walls defining a chamber 29 and a pipe 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 the flange 15 of the hollow 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 the pipe 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 1 and 2 as shown in figure 1. Three of the initially described elements pertaining to one of the three series 3, 4 and 5 are then fixed to this unit.
  • the element of the series 3 is selected to enable a filter 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, the connectors 25 of the elements of this series having different diameters as stated.
  • the element of the series 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).
