ABSTRACT:
A vehicle air brake system includes a conventional automotive air compressor operated by the vehicle engine for charging a storage reservoir with compressed air. Air is communicated through an air dryer which cleans and dries the air before it is communicated to the storage reservoir. A governor is responsive to the pressure level in the storage reservoir to generate a pressure control signal in response to the pressure level in the reservoir reaching a predetermined level. The compressor is unloaded by the signal from the governor so that, while it may continue to be operated by the vehicle engine, it does not compress air. The unloading signal also opens the purge valve on the air dryer, which backflows a quantity of air through the air dryer to regenerate the desiccant. A connector is provided to connect the air brake system with an external shop air supply, so that the reservoir may be kept charged while the vehicle is parked so that the vehicle may be moved immediately after the vehicle engine is started. The connector is communicated to the supply or inlet port of a conventional inversion valve, which normally permits communication between the supply and delivery ports thereof. The delivery port of the inversion valve is communicated through the air dryer to the storage reservoir. The inversion valve is responsive to the signal from the governor to terminate communication between the supply and delivery ports, and to vent the delivery port to atmosphere.
