Abstract
A filter assembly comprises a filter head 10 and a filter housing 12, the filter housing 12 being of substantially square or rectangular cross-section. Coupling means (22, Figure 3 and 26, Figure 5) secure the filter head 10 to the filter housing 12 in a first, operational, position (Figure 1), but also allow for the filter head 10 to be rotated, relative to the filter housing 12, to a second position (Figure 2) wherein the coupling means still secure the two together. The coupling may take the form of a bayonet type connection. The housing 12 preferably contains a filter element or cartridge which is replaced at the end of its working life.
Description
FILTER ARRANGEMENT
This invention relates to a filter arrangement suitable for use in a fuel system for use with a compression ignition combustion engine. In particular, the invention relates to a filter arrangement of the type in which the filter housing is of substantially square or rectangular crosssection.
Filter arrangements in which the filter housing is of square or rectangular cross-section are advantageous in that the filtration area is increased without significantly increasing the overall dimensions of the filter arrangement. The increase in filtration area increases the effective working life of the filter. However, one disadvantage is that it is difficult to assemble the filter arrangement and achieve sufficiently good seals between the filter housing and a filter head to avoid fuel leakage.
According to the present invention there is provided a filter assembly comprising a filter head and a filter housing arranged to be secured to the filter head, the filter housing being of substantially square or rectangular cross-section, and coupling means associated with the filter housing and the filter head for use in securing the filter housing to the filter head, wherein when the filter housing occupies a first position relative to the filter head, the coupling means permits removal of the filter housing from the filter head, the coupling means being arranged to secure the filter housing to the filter head when the filter housing occupies a position angularly displaced from the first position about the axis of the filter housing.
The coupling means conveniently takes the form of a bayonet-type connection including a plurality of first coupling components, for example recesses, provided on the filter housing and a plurality of second coupling components, for example projections, provided on the filter head.
The filter housing may be arranged to carry a filter cartridge which is intended to be replaced at the end of its working life. Alternatively, a filter element may be located within the filter housing, the assembly of the filter housing and filter element being replaced when the filter element becomes clogged.
It will be appreciated that the use of a bayonet-type connection permits relatively simple assembly of the filter arrangement without requiring the use of any specific tools.
The invention will further be described, by way of example, with reference to the accompanying drawings, in which:
Figure 1 is a perspective view of a filter arrangement in accordance with an embodiment;
Figure 2 is a view similar to Figure 1 with the filter housing rotated relative to the filter head;
Figure 3a is a perspective view of part of the filter housing;
Figure 3b is similar to Figure 3a illustrating a modification;
Figures 4a and 4b are diagrams illustrating the operation of the invention;
Figures 5 and 5n illustrate several modifications to the arrangement of
Figure 1;
Figure 6 is a diagrammatic sectional view of a filter arrangement similar to that of Figure 1; and
Figure 7 is a view similar to Figure 3a illustrating an alternative embodiment.
The filter arrangement illustrated in Figures 1 and 2 comprises a filter head 10 to which is secured a filter housing 12. The filter head 10 includes a plurality of inlet and outlet ports 14, some or all of which are connected, in use, to appropriate inlet and outlet lines of an associated fuel system. The filter head 10 further includes a hand primer arrangement 16 for use in priming the filter arrangement, and a mounting bracket 18 for use in securing the filter arrangement in position relative to an associated engine. As described hereinafter, the filter housing 12 is angularly adjustable relative to the filter head 10 in order to secure the filter housing 12 in position, and conveniently the filter head 10 and filter housing 12 are provided with appropriate markings to provide an indication as to when the filter housing 12 occupies a locked or in use position relative to the filter head 10.
Figure 3a illustrates the filter housing 12 removed from the filter head 10. The filter housing 12 is of substantially square cross-sectional shape and is intended to receive, in use, a pleated paper filter member for use in removing contaminants from a flow of fuel through the filter arrangement. An upper part 20 of the filter housing 12 is of increased wall thickness, and first bayonet connector components in the form of recesses 22 are provided in the upper part 20, the recesses being arranged to receive, in use, corresponding bayonet connector components provided on the filter head 10 to secure the filter housing 12 to the filter head 10.
Figure 5 illustrates the filter head 10 with the filter housing 12 removed therefrom, and as illustrated in Figure 5, the filter head 10 includes, at its lower end, a flange 24 of substantially square cross-section having second bayonet connector components in the form of outwardly extending projections 26 located at the apices thereof. Figure 5a illustrates several alternative shapes for the projections 26.
Figures 4a and 4b illustrate, diagrammatically, the technique for assembling the filter arrangement. In Figure 4a, the filter housing 12 is moved to a position in which the flange 24 and projections 26 are introduced into the part of the interior of the filter housing 12 defined by the upper part 20 with the projections 26 located adjacent the corners of the upper part 20. From this position, the filter housing 12 is rotated relative to the filter head 10 by an angle of approximately 45 , such rotation resulting in the introduction of the projections 26 into the recesses 22 to secure the filter housing 12 to the filter head 10. As illustrated in Figure 3a and Figure 5, the recesses 22 and projections 26 are shaped to include ramped regions, cooperation of the ramped regions resulting in the filter housing 12 moving axially relative to the filter head 10 during angular movement of the filter housing 12, such axial movement causing the compression of seals located adjacent the upper end of the filter housing 12 to provide a substantially fluid tight seal between the filter housing 12 and filter head 10. By using appropriately shaped projections 26 and recesses 22, a positive indication can be given the user that the filter housing 12 has reached its fully closed position relative to the filter head 10, and such shaping may also act to reduce the risk of undesirable rotation of the filter housing 12 relative to the filter head 10, in use.
The arrangement illustrated in Figure 3b is similar to that of Figure 3a but differs in that the upper part 20 of the filter housing 12 is shaped to include regions of slightly reduced wall thickness thus reducing wastage.
Figure 6 illustrates a modification in which rather than the upper part 20 being an integral part of the filter housing 12, the part 20 is defined by a separate collar including an inwardly extending lower flange 22a which is engageable with an outwardly extending lip 27 of the filter housing 12, the lip 27 conveniently being defined by the roll produced when securing the lid of the filter housing 12 to the peripheral wall thereof.
As described hereinbefore, the part 20 is provided with recesses 22 which are arranged to receive projections 26 provided on the filter head 10 to secure the filter housing 12 in position. As the filter housing 12 moves towards its operative position, seal 28 provide a substantially fluid tight seal between the filter housing 12 and filter head 10. The seals are conveniently radial seals, thus minimising the effort required to move the housing 12 to its operative position. The upper part of the seal 28 may not be in contact with the lower surface of filter head 10, and in these circumstances, the upper part of the seal 28 is conveniently dished to guide fuel flow and reduce spillage. The seal 28 has the advantage that when the housing 12 is removed from the filter head 10, the seal 28 reduce spillage of fuel from the housing 12. Alternatively, the seal may be located to be compressed in the axial direction between the filter housing and head to form a substantially fluid tight seal. A member 30 is also conveniently trapped between the filter housing 12 and filter head 10, the member 30 acting to resist undesirable relative angular movement of the filter housing 12 and filter head 10. The member 30 may take the form of a helical spring, a formed spring steel fabrication or a rubber fabrication.
As shown in Figure 6, a filter element 32 is located within the filter housing 12, the element 32 being of the type in which fuel flows through a pleated paper filter member 34 in a direction from an outer chamber 36 to an inner chamber 38, the filtered fuel from the inner chamber 38 flowing through an outlet of the filter arrangement, and subsequently flowing to an appropriate high pressure fuel pump.
Although the arrangement illustrated in Figure 6 is of the type in which the filter element 32 and housing 12 are removed and disposed of when the filter member 34 reaches the end of its useful working life, the collar being removed from the housing 12 and located upon the replacement housing, it will be appreciated that the invention is also applicable to an arrangement in which a removable filter cartridge is located within the filter housing 12, only the filter cartridge being replaced when the filter element reaches the end of its useful working life.
Figure 7 illustrates a filter housing 12 similar to that of Figure 3a but which the upper part 20 is provided with outwardly extending projections 26 which are receivable, in use, within recesses provided in a wall which extends downwardly from an appropriate filter head.
Conveniently, the connector components are unevenly spaced around the periphery of the filter housing 12 and head 10 resulting in the filter housing only being capable of being secured to the filter head in one angular position.
It will be appreciated that the invention is applicable to a range of filter arrangements, for example arrangements including water collection chambers either with manual or automatic water drainage arrangements, filter arrangements which do not include a primer arrangement, arrangements including a sedimenter chamber in addition to the filter, and arrangements incorporating electrically powered fuel pumps.
Further, it will be appreciated that the invention is applicable to filter arrangements having filter housings of increased axial length to permit filter elements of increased filtration area to be used.
The invention is also applicable to a filter arrangement of the type in which the filter element is replaced by a sedimenter, thus rather than the fuel being passed through a filter element arranged to collect contaminants carried by the flow of fuel, the filter or sedimenter incorporates appropriate baffle means to define a suitable flow path to permit the separation of contaminants from the flow of fuel under the action of gravity.
