The purge piston moves in response to air pressure causing the purge valve to open to atmosphere and partially closing off the supply of air from the compressor this will be. Some air dryers incorporate a pressure governor which outputs a control order to an air compressor outside the air dryer or to a drain valve in the air dryer based on the air pressure received from an air tank for storing dry air and maintains the pressure in the air tank within a prescribed range refer to patent literature 1 for example. The governor unloads the compressor by allowing air pressure to fill the line leading to the compressor unloader mechanism. Repair or replace as needed.
