The pilot/unloader valve is the "brains" of the air compressor, like the pressure switch is on an electric air compressor. It senses the pressure in the tank and is mated to the throttle control assembly. Once the unit is started from 0 PSI, the pilot valve/throttle control valve combo starts in a "load" position and kicks the engine into it's higher, running RPM. Once the compressor reaches its maximum PSI, the pilot valve/throttle control kicks the engine down to its slower, ideling RPM speed and vents the air out of an exhaust port in the pilot valve.
