ABSTRACT:
In a rotary compressor having a motor element and a compression element contained in a sealing case, an oil separating device for separating lubricating oil from an oil-containing refrigerant is attached on the rotor of the motor element. The oil separating device has a circular plate having a diameter substantially equal to the outer diameter of the rotor, wherein a channel-like recess projecting toward the rotor is formed in the circular plate at a position deviated from its central portion; the lower surface of the channel-like recess is adapted to be firmly connected to the upper surface of the rotor, and an aperture is formed at the central portion so that the discharge tube is loosely inserted in the aperture.
