ROTARY COMPRESSOR

A rotary compressor: a casing; a plurality of bearings provided in an internal space of the casing; at least one cylinder that is provided between the bearings to form a compression space and has a vane slot; a rolling piston that is 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 and, along with the rolling piston, separates the compression space into a suction chamber and a discharge chamber; a discharge cover that comes with 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, so that the refrigerant discharged to the noise reducing space is supplied to the side of the vane. Accordingly, the refrigerant discharged via the discharge port is supplied to the side of the vane through the bypass flow path before released to the casing, thereby applying uniform force to opposite ends of the vane.
