Abstract
A rotary compressor: a casing; a plurality of bearings provided in an internal space of the casing; at least one cylinder provided between the bearings to form a compression space and has a vane slot; a rolling piston accommodated in the compression space to perform an orbiting movement; at least one vane that is slidably inserted into the vane slot of the cylinder, the at least one vane configured to separate the compression space into a suction chamber and a discharge chamber; a discharge cover including a noise reducing space to accommodate refrigerant discharged from the compression space; and a bypass flow path that allows the noise reducing space of the discharge cover to be connected between a sidewall of the vane slot and a side of the vane facing the sidewall.
