OIL SEPARATOR FOR VEHICLE AIR SYSTEM

摘要

An oil separator (10) for use in a vehicle air system includes a recycling valve (30) for removing coalesced oil. The recycling valve (30) may include a piston (78) movable in a cylinder in response to a control air pressure to open the recycling valve and thus drain coalesced oil from a sump (70) 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 (50) for directing air into the cartridge (42) 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 (55) on the separator releases air when the pressure exceeds a predetermined pressure.
