Abstract
An air compressor system having an unloader valve which is directly mechanically activated by an air compressor motor's centrifugal mechanism to allow the motor to reach a predetermined speed before a load is applied is disclosed. The unloader valve is mounted directly on an end flange of the motor and communicates with an outlet conduit of the air compressor to allow the compressed air from the air compressor to vent to atmosphere until the motor reaches the predetermined speed.
