ABSTRACT:
A compressor comprises a sealed chamber to which a suction pipe and a discharge pipe are communicated, a motor unit fixed in the sealed chamber and consisting of a stator and a rotor for generating rotating force by electromagnetic interaction between the stator and rotor, and a compression unit sucking, compressing and discharging compressible fluid according regular volume change and opening/closing of valve caused by rotating force of the motor unit, wherein the compression unit is disposed in the rotor to miniaturize and lighten the compressor, to reduce input energy of the motor unit, and to reduce vibration noise.
