ABSTRACT:
An air compressor includes a chassis that supports thereon a motor, a transmission set, and a plurality of extendible barrels. The transmission set includes a clutch that is operatively coupled to the motor through a belt. Two eccentric rotation members are respectively arranged on opposite sides of and coupled to the clutch. Each eccentric rotation member is coupled to a crank arm, which has a moving end connected to the extendible barrel. The extendible barrel is provided with an air inlet port and an air outlet port. When the motor is set in operation, the transmission set drives the extendible barrels to move carry out reciprocal and axial compression to delivery compressed air. The present invention features easy maintenance and can carry out a noise-free operation.
