The compressed air will go to the inlet port (15) for the air dryer (8). The dry compressed air goes to the reservoir (18) for the air supply. The air pressure in reservoir (18) will eventually reach the pressure setting of the governor (2) .
The compressed air will flow from reservoir (18) to the supply port of the governor (4). Governor (2) will allow the compressed air to pass from the reservoir (18) through the governor (2) .
The compressed air will flow from the delivery port (3) of the governor (2) to the unloader port (14) of the air compressor (5). The compressed air will activate the unloader system of the air compressor (5). The discharge valve (10) of the air compressor (5) will be closed. The inlet valve (9) of the air compressor (5) will close.
When the air pressure in the air reservoir (18) drops to the minimum pressure setting of the governor (2), the governor (2) will no longer allow the compressed air to pass through the governor (2). The governor (2) will release the compressed air that is in the line between the delivery port (3) for the governor (2) and the control port (16) for the air dryer (8). This will close the air dryer purge valve.
The compressed air between the unloader port (14) for the air compressor (5) and the delivery port (3) of the governor (2) will be released through the exhaust port (1) for the governor (2). After unloading, the unloader piston returns the leaf valve to the loaded position. This seals the unloader port.
The compression of air will resume.
