摘要： A purge valve for use with an air drying system is provided. The valve includes a housing or body, a piston disposed within the body, and a valve in communication with the piston. The respective geometries of the piston body and the valve define a circumferential cavity between and around the piston body and the valve. A sealing means is disposed within the circumferential cavity for forming a seal between the valve and the body. A plurality of guide members attached to or formed integrally with the valve provide positional stability to the valve within the body and provide enhanced airflow in, through, and around the valve.

摘要： An improved system and method for mounting an air dryer is provided. The improved system and method employs a single centralized special fitting that secures the air dryer manifold to a reservoir. The bore in which the fitting is disposed is used to communicate air from the reservoir to the air dryer in order to purge the desiccant in the air dryer. The mounting assembly includes anti-rotational mechanisms which prevent the air dryer from rotating about its axis. The mounting assembly may also include a reservoir and a mounting bracket for the reservoir which uses less than 75 percent of a truck mounting rail height.

摘要： An air charging arrangement for an air brake system of a vehicle driven by an internal combustion engine. The arrangement includes a hydraulic motor for driving an air compressor, which is mounted to the vehicle at a location that is thermally isolated from the engine. The arrangement may also include an air compressor controller that places the air compressor in a non-operating state when air pressure in an air reservoir is at or above a predetermined amount. In one embodiment, the air compressor is self-lubricated and air cooled.

摘要： A drain valve for a vehicle compressed air system, which separates dirt, water, debris and other relatively heavy objects from a compressed air stream. The drain valve includes a sump with a tangential inlet. The tangential inlet creates a vortex within the sump that collects relatively heavy objects at the bottom of the sump and allows the compressed air to exit the drain valve through an outlet port located at the top of the drain valve. A pressure actuated valve and drain port allows for the water to be discharged from the drain valve while retaining the pneumatic signal.

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.
