摘要： An air drying system for a vehicle including a membrane air dryer is provided. The air dryer is supplied with a stream of compressed air that has a low and constant concentration of oil vapor. A coalescing filter element may be used to maintain the oil vapor concentration. The filtered material may be discharged from the coalescing filter by a pressure swing drain valve, which discharges the filtered material upon unloading of the compressor.

Apparatus (60) for the separation of a fluid into permeate and retentate portions comprises a plurality of transverse sheet membrane wafers (10), vessel means (61) providing a first port (68) for receiving the fluid, a second port (69) for withdrawing the retentate and a third port (70) for withdrawing the permeate, means for compressing (74) the plurality of wafers in axial alignment, and permeate chamber means (72) within said vessel, separate from the feedstream and the retentate by the means for compressing (74) and peripheral support means (11). Separate methods are also provided for the manufacture of the wafers as well as for the separation of fluid feedstreams into permeate and retentate portions. A method of the latter type includes the steps of feeding the fluid into a module containing a plurality of semipermeable membrane sleeves arranged chord-wise in parallel alignment and oriented perpendicularly with respect to the longitudinal axis of the module; providing separate chambers for the permeate, communicating with the interior of the sleeves, and for said retentate, communicating with the areas between the membrane sleeves; and removing the permeate and retentate from the module.

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.
