摘要： In a rotary piston compressor and refrigerating equipment employing the rotary piston compressor, the interior of a cylinder chamber is divided into a suction chamber and a compression chamber by a vane which is formed unitarily with a roller. The rotary bushing on the compression chamber side which supports the vane is so arranged as to be moved with a specific pressure, so that a communicating passage for communication between the compression chamber and a space on the discharge side will be opened and closed with the movement of the rotary bushing on the compression chamber side.
