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), including an integral purge volume (34), 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). A pressure equalizing mechanism (57) is disposed between the primary reservoir (18) and the secondary reservoir (12) for keeping pressure in the two reservoirs (12,18) equal. 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).

[ What is claimed is:] [1.] An air supply system for a heavy motor vehicle brake system comprising:a compressor for supplying compressed air;an air dryer connected to receive compressed air from said air compressor including a desiccant bed through which the compressed air can flow to provide a clean and dry compressed air source for operating the brake system;a secondary reservoir;a housing connecting said air dryer and said secondary reservoir together as a unitary module;a primary reservoir located away from said secondary reservoir;control components disposed in said housing for controlling air flow from said air compressor through said air dryer for charging said primary reservoir and said secondary reservoir with compressed air;a purge volume formed integral with said secondary reservoir; and,said control components also control air flow from said purge volume through said air dryer desiccant bed to atmosphere to purge said air dryer.
