More Information
Summary:A rotary compressor includes at least one cylinder in which a discharge guide groove is disposed at one side of a vane slot; a roller orbitably provided in the cylinder, and disposed with a hinge groove on an outer circumferential surface thereof; a vane in which one end portion thereof is rotatably inserted into the hinge groove of the roller, and the other end portion thereof is slidably inserted into the vane slot of the cylinder; and a plurality of bearing plates that seals both side surfaces of the cylinder, and at least one side of which is disposed with a discharge port to communicate with the discharge guide groove. The discharge port communicates with a refrigerant residual space defined between the vane slot and the discharge guide groove. Refrigerant in the refrigerant residual space may be discharged even after the roller passes through the discharge guide groove.
