ABSTRACT:
An air supply system for a motor vehicle air brake system incorporating a desiccant type air dryer. The purge capacity of the air dryer is enhanced providing greater water and contaminant removable characteristics for the air dryer. The system incorporates a pressure reducing element and a control system for the system compressor causing air passing through the air dryer to be at a higher pressure than that necessary for charging the system reservoir. The higher pressure air supplied to the air dryer provides greater volumetric capacity for the purge volume of the air dryer. In this way an air dryer purge volume of a given size provides a greater purge capacity.
