ABSTRACT:
A rotary compressor comprising a cylindrical stator, a rotor rotatably mounted within the stator defining a number of stator chambers, a plurality of gas-blocking vanes equiangularly disposed between the inner peripheral surface of the stator and the outer surface of the rotor, wherein the outer peripheral surface of the rotor is formed with a plurality of wavy compressive surfaces and the center line of said vanes are not aligned with the center of the rotor so as to make the pressure angle between the vanes and the rotor approach 0.degree. during the performance of the compression work, so that the frictional resistance formed between the rotor and the vanes will be reduced to the minimum.
