Abstract
A serviceable filtering oil removal cartridge for use in a compressed air assembly of a vehicle air brake system includes a housing having a first end and a second end. A filtering element is disposed within the housing for agglomerating and removing oil from compressed air entering the oil removal cartridge. A load plate is disposed within the housing for supporting the filtering element. The load plate includes a connecting portion dimensioned to allow the oil removal cartridge to be removed and installed as a single unit. The connecting portion is preferably a threaded annulus. A thermal vent can be included, wherein pressure is released from the oil removal cartridge upon reaching a threshold temperature.
Claims47
A compressed air system for an air brake assembly comprising:
- a compressor for generating pressurized air for use in operating the air brake system;
- a serviceable oil removal cartridge disposed, downstream from the compressor for filtering oil from the pressurized air, the oil removal cartridge having an outer housing enclosing a filtering element and a load plate for supporting the filtering element, the load plate including a connecting portion dimensioned to allow the oil removal cartridge to be removed and installed as a single unit;
- and
- an air dryer disposed downstream from the oil removal cartridge for removing water from the pressurized air.
A disposable filtering oil removal cartridge for use in a compressed air system of a vehicle air brake system comprising:
- a housing having a first end and a second end and having an air inlet and air outlet;
- a fibrous filtering element disposed within the housing between the air inlet and air outlet for agglomerating and removing oil from the compressed air entering the oil removal cartridge, wherein said filtering element has an elongated surface parallel to the flow of air entering the inlet of the housing along which the compressed air may pass and a width perpendicular to said inlet air flow through which the compressed air passes to reach the air outlet;
- and
- a load plate disposed within the housing for supporting the filtering element within the housing, the load plate including a connecting portion dimensioned to allow the oil removal cartridge to be removed and installed as a single unit.
A method for installing and removing an oil removal cartridge for a compressed air system of a vehicle air brake system comprising the steps of:
- providing a housing;
- mounting a filtering element on a load plate disposed within the housing;
- providing a threaded annulus in the load plate, the threaded annulus defining a passage;
- threadably engaging the threaded annulus of the load plate with a threaded member of a body assembly;
- and
- threadably disengaging the threaded annulus of the load plate from the threaded member of the body assembly when the oil removal cartridge needs to be replaced.
An oil removal cartridge comprising:
- a housing including an air inlet and an air outlet and a threaded annulus for securing the cartridge onto another threaded member;
- and
- a filtering element disposed within the housing between the inlet and outlet, wherein said filtering element is a fibrous material and includes an elongated surface parallel to the flow of air entering the inlet of the housing along which the compressed air may pass and a width perpendicular to said inlet air flow through which the compressed air passes to reach the air outlet.
A compressed air system comprising:
- (a) a compressor for generating compressed air;
- (b) a removable oil removal cartridge disposed downstream from the compressor for agglomerating and removing oil vapor entrenched in the compressed air, wherein the oil removal cartridge comprises:
- (i) a housing including an air inlet and an air outlet and a threaded annulus for securing the cartridge onto another threaded member;
- and
- (ii) a filtering element disposed within the housing between the inlet and outlet, wherein said filtering element is a fibrous material and includes an elongated surface parallel to the flow of air entering the inlet of the housing along which the compressed air may pass and a width perpendicular to said inlet air flow through which the compressed air passes to reach the air outlet;
- and
- (c) an air dryer disposed downstream from the oil removal cartridge for removing water from the compressed air.
An oil removal cartridge comprising:
- a housing;
- and
- a thermal vent, including a plug that releases air pressure from within the housing once a threshold at a predetermined temperature.
A thermal vent for an oil removal cartridge comprising:
- a housing;
- and
- a plug associated with the housing, wherein said plug releases air pressure from within the housing once a threshold temperature is reached.
A pressure release plug for an oil filter, wherein said plug melts at a predetermined temperature thereby releasing pressure from within the oil filter.
