ABSTRACT:
An air compressor system having an actuator for controlling the energization of the primary and start windings of the compressor motor and the state of a relief valve is disclosed. No power is applied to either of the windings and said valve is closed when the actuator is disposed in the first position. Movement of the actuator to the second position energizes both of the windings and opens the relief valve so that the motor and compressor can reach full speed before a load is applied. When the actuator is released and moved to the third position, the start winding is deenergized and the relief valve is closed to allow an air storage tank to be filled.
