Definitions
- the present invention relates to a vehicle air dryer and in particular to a vehicle air dryer desiccant cartridge.
- the provision of air drying apparatus in vehicle air systems is well known.
- the air dryer apparatus is typically positioned intermediate an air source, for example a compressor, and a reservoir.
- the air dryer includes a desiccant material, for example a moisture adsorbing material such as silica gel, which removes moisture from the air supplied by the compressor so as to prevent said moisture being deposited downstream in the vehicle air system where it may over time damage components of the air system.
- a desiccant material for example a moisture adsorbing material such as silica gel, which removes moisture from the air supplied by the compressor so as to prevent said moisture being deposited downstream in the vehicle air system where it may over time damage components of the air system.
- a desiccant material for example a moisture adsorbing material such as silica gel, which removes moisture from the air supplied by the compressor so as to prevent said moisture being deposited downstream in the vehicle air system where it may over time damage components of the air system.
- the air dryer is periodically purged to atmosphere with dry
- the desiccant material is typically provided in a removable canister, hereinafter referred to as a cartridge, which is releasably attached to the air dryer.
- the cartridge is periodically replaced so as to take into account degradation in the performance of the desiccant material over time.
- the air supplied by the compressor includes a mist of very fine oil droplets.
- the oil droplets are generated from the lubricating oil present in the compressor by the reciprocating action of the compressor.
- the oil mist typically passes through the air dryer and is subsequently deposited in the reservoir or further downstream in vehicle air system. While oil deposited in this manner is much less likely to damage air system components in the same manner as moisture, its deposit may lead over time to such problems as, for example, the constriction of narrow passageways in air system components and the degradation of elastomeric seals. It is an object of the present invention to provide an improved air dryer which seeks to prevent the transmission of oil therethrough.
- an air dryer desiccant cartridge comprising a base having an inlet and an outlet, a casing comiected to the base to define a cavity therebetween, wherein the cavity contains a filter and a desiccant, the filter being arranged upstream of the desiccant such that during normal operation of the cartridge fluid flow entering the cartridge through the inlet passes through the filter and then on to the desiccant before reaching the outlet, and during purging of the cartridge purge flow entering the outlet passes through the desiccant before reaching the filter, wherein further the cartridge includes a valve operable to permit a portion of the purge flow to bypass the filter.
- valve ensures that all of the fluid entering the cartridge during normal operation is routed through the filter before reaching the desiccant, while permitting the purge flow to be split such that a portion of the purge flow is directed through the filter in reverse direction, while the remainder of the purge flow bypasses the filter.
- the valve preferably includes a valve member which is urged to a closed position, thereby preventing the flow of fluid through the valve, by fluid flow entering the cartridge through the inlet.
- the valve member may take the form of a flexible member.
- the flexible member may be provided with a proximal portion fixed to a feature of the cartridge, and a movable distal portion.
- the flexible member may be positioned in a lower region of the cartridge between the filter and the base.
- the valve may comprise a flow passage having a movable valve member contained therein.
- the cartridge may further include a sump associated with the filter.
- the sump serves to collect liquid removed from incoming airflow entering the cartridge.
- the sump is located in the vicinity of the valve such that purge flow directed through the valve entrains any liquid contained in the sump.
- the desiccant container may be substantially cylindrical.
- the container may be at least partially received with the annulus of the filter.
- the container may comprise a first portion having a diameter less than that of the annulus and a second portion having a diameter greater than that of the annulus.
- the transitional portion of the container between the first and second portions may define a seat configured to receive the filter.
- a base member for a desiccant cartridge comprising an upper portion configured to receive a filter of a desiccant cartridge, and a lower portion adapted to rest against a base of a desiccant cartridge, the lower portion further including a flow passage and a blocking means operable to open and close said flow passage.
- the upper portion of the base member is provided with a seat configured to receive and support the filter.
- the seat may be provided with one or more engagement features which, in use, serve to locate the filter relative to the base member.
- the engagement features may comprise one or more projections.
- the aforementioned projections may take the form of one or more sprung fingers. Additionally, the seat may be contoured.
- the base member may preferably be manufactured from a plastics material by an injection moulding operation.
- the flexible rib or skirt may advantageously be co-moulded with the base member.
- Figure 6b shows a perspective view of a seat of the valve of figure 6a
- FIG 1 shows a cross-sectional view of a desiccant cartridge, generally designated 10, which is constructed in accordance with the present invention.
- the cartridge 10 includes a base member 12, a casing 14 and an inner cup 16.
- the base member 12 is provided with a central aperture 18 surrounded by a plurality of secondary apertures 20.
- the central aperture 18 is threaded in order that the cartridge 10 as a whole can be screw fitted to a complementary threaded spigot of an air dryer housing.
- the base member 12 is further provided with an annular seal mount 22 which carries an elastomeric seal 24.
- the seal 24 ensures that, in use, the cartridge 10 fits in a leak tight manner to an air dryer housing.
- the seat member 50 is shown in greater detail in figure 2a and comprises an annular base 58 having an upstanding wall 60 at an inner edge thereof.
- the outer edge of the base 58 is provided with a plurality of upstanding fingers 62 each having a projection 64 at their distal end.
- the annular base 58 is substantially flat, however it will be appreciated that the base may be configured so as to assist in the location and positioning of the filter 38 with respect thereto.
- the base 58 may be provided with one or more features, such as projections, which interengage with complementary features of the filter 38.
- the base 58 may be contoured, for example having a concave or convex shape, to assist with the location and positioning of the filter 38.
- the seat member 51 is shown with the fingers 62, however these may optionally be omitted.
- the cartridge 10 is attached to the body of an air dryer apparatus (not shown) such that incoming moist air (indicated by arrow 84) and oil mist (indicated by arrow 86) from a compressor is directed into the cartridge 10 through the secondary apertures 20.
- the moist air and oil mist is directed between the base 28 of the cup 16 to the filter 38.
- Upon passing through the filter material 78 a significant proportion of any oil mist is removed from the air flow.
- the filter material 78 acts to remove the oil mist by coalescing the individual droplets forming the mist into larger droplets which are not carried by the air stream passing through the filter material 78.
- FIG. 6a and 6b shows the drain valve 168 in greater detail.
- the valve 168 includes an inlet 170 in fluid communication with the sump 166 and an outlet 172 in fluid communication with the first portion 158 of the inlet chamber 146. Between the inlet 170 and outlet 172 there is provided a valve chamber 174 containing a valve member 176 which, in the embodiment shown, is substantially spherical. The chamber is further provided with a seat 178 for the valve member 176 surrounding the inlet 170, and a plurality of bypass channels 180 adjacent the outlet 172.
- the valve member 176 is movable longitudinally within the valve chamber 174 as indicated by arrow 182.
- FIG 8 This second instance is illustrated in figure 8 by arrows 208.
- the liquid from the sump 166 is delivered to the port 204 and thereafter vented to atmosphere through a vent port (not shown) of the air dryer body 188.
- the regeneration flow of dry air is split between the filter element 154 and the drain valve 168.
- the portion passing through the filter element 154 entrains any liquid or particulate matter retained by the material of the filter element 154.
- the portion of the regeneration flow which passes through the drain valve 168 entrains any liquid retained in the sump 166.
