PROBLEM TO BE SOLVED: To provide a rotary compressor reduced in manufacturing cost by reducing an excessive compression loss caused by the flow resistance of a refrigerant in a discharge hole of a compression section. SOLUTION: This rotary compressor has compression section comprising a cylindrical cylinder, two end plates for closing both ends of the cylinder, a piston held by an eccentric section of a rotary shaft driven to rotate by a motor, revolving in the cylinder along a cylinder inner wall of the cylinder and forming an operation chamber between the cylinder inner wall and itself and a vane projecting in the operation chamber from the inside of a vane groove of the cylinder and partitioning the operation chamber into a suction chamber and a compression space by abutting on a piston, a sealed compressor casing for storing the compression section, a suction hole arranged in the cylinder and making the suction chamber communicate with the low pressure side of a refrigerating cycle, and the discharge hole arranged in the one end plate and communicating the compression space with the high pressure side of the refrigerating cycle. An auxiliary discharge hole separated from the discharge hole is arranged at the one end plate. COPYRIGHT: (C)2009,JPO&INPIT
