Abstract
A rotary compressor provided that may include a casing, a cylinder, a roller, and at least one vane slidably inserted into the roller, and the roller may have at least one bypass passage through which spaces on both sides of a contact point based on a rotational direction of the roller communicate with each other. Through the at least one bypass passage, residual refrigerant remaining in a compression space even after a discharge stroke may be bypassed to a suction chamber, thereby minimizing the refrigerant remaining in the compression space after the discharge stroke. Also, loss due to overcompression in a residual space may be suppressed or prevented while reducing suction loss due to the introduction of overcompressed high-pressure refrigerant by the bypassing the refrigerant in the residual space toward a suction side in advance.
