PURPOSE:To eliminate complicated piping by providing a check valve between a suction tube and a compression chamber while fixing a differential pressure valve to the peripheral surface of an enclosed vessel and connecting one end of a pressure introducing path between the check valve and the compression chamber and the other end of the path to the differential pressure valve. CONSTITUTION:A check valve B is provided between a suction tube 13 and a compression chamber 8, and fixing a differential pressure valve V to the peripheral surface of an enclosed vessel 1, a path between the compression chamber 8 and the check valve B communicates with the differential pressure valve V through a pressure introducing path 40. Thus because the check valve B can be internally provided in a rotary compressor, complicated piping or the like can be avoided. While because the differential pressure valve V is provided being arranged in a system, an increase of mounting labor hours can be avoided. |
