摘要： A charging system used for supplying compressed air to a destination includes a compressor for generating the compressed air and a reservoir capable of being alternately discharged and recharged with the compressed air. A supply line fluidly connects the compressor, the reservoir, and the destination. A control valve positioned along the supply line is used in controlling flow of the compressed air from the charging system to the destination. A first branch line and a second branch line are positioned between the reservoir and the supply line. A check valve is positioned along the first branch line that when opened allows the compressed air to flow out of the reservoir into the supply line and when closed prohibits the compressed air from flowing into or out of the reservoir. A pressure protection valve is positioned along the second branch that opens to allow the compressed air to flow into the reservoir when the pressure in the supply line is above a threshold pressure.

摘要： An oil separator for use in a vehicle air system includes a recycling valve for removing coalesced oil. The recycling valve may include a piston movable in a cylinder in response to a control air pressure to open the recycling valve and thus drain coalesced oil from a sump under the influence of residual air pressure in the sump. The separator may include a fixture for mounting the separator to a vehicle, including a plurality of ports extending from an inlet port for directing air into the cartridge with a combined flow area at least equal to the flow area of the inlet port. The plurality of ports preferably extend at a right angle to the direction of flow of air through the inlet port. A safety relief valve on the separator releases air when the pressure exceeds a predetermined pressure.

摘要： A method and apparatus for mounting an air dryer to a commercial vehicle is provided. The end caps of the membrane air dryer are used to retain the membrane air dryer core and attach the membrane air dryer to the surface of the air supply reservoir. Bosses can be welded to the external surface of the air supply reservoir, which can then be used to mount the membrane air dryer by bolting the end caps to the bosses. The method and apparatus can be applied to two or three tank air supply reservoir systems. A disengagement tank may be included within the air dryer system, in place of a coalescing filter, to reduce the amount of moisture that reaches the membrane air dryer core.

摘要： An air dryer and reservoir assembly for providing compressed air from an air compressor (20) on a heavy motor vehicle which includes an air dryer (14) connected to receive compressed air from the air compressor (20) and a secondary reservoir (12) for storing compressed air which passes through the air dryer (14), with the air dryer (14) and the secondary reservoir (12) being securely attached to a housing (16) to form an air dryer reservoir module (10). A primary reservoir (18) for storing compressed air from the air dryer (14) is located remote from the air dryer reservoir module (10). Components located within the housing (16) control air flow between the air dryer (14) and the primary and secondary reservoirs (18,12) and also monitor the pneumatic brake system circuits fed by the primary and secondary reservoirs (18,12). In the event of a failure of either of the pneumatic brake system circuits speed of the vehicle is limited.

摘要： An automatic slack adjuster for a vehicle braking system includes a yoke assembly which is pivotally mounted on the adjuster body and in which is adapted to be connected to a push rod actuated by a fluid pressure actuator. The yoke assembly includes a recess having an entrance which is adapted to receive the end of the push rod. An adapter member is threaded on the end of the push rod received in the recess, and a U-shaped connector penetrates the body of the yoke to engage a circumferentially extending groove on the adapter, to thereby define a nonthrust transmitting connection between the yoke and the push rod. The yoke assembly defines a pair of thrust receiving surfaces which circumscribe the entrance to the recess, and a thrust washer slidable on the push rod is held at a thrust transmitting engagement with one of the thrust receiving surfaces by a nut which is threaded on the end of the push rod. The adapter is stepped to define larger and smaller surfaces with a shoulder therebetween which is adapted to engage the other thrust transmitting surface. Consequently, braking thrust is exerted on the yoke assembly through the push rod, the thrust washer, and the one thrust receiving surface, but if the thrust washer is moved out of thrust-transmitting engagement with the one surface, thrust may be transmitted to the other surface through the shoulder.

摘要： A purge exhaust processor includes an inlet chamber, a sump chamber, a selectively charged surface in the inlet chamber, and an orifice. The inlet chamber receives purge exhaust including at least one of air, water vapor, oil aerosol, and water aerosol.
