PURPOSE:To save the space by forming a path communicating between a suction chamber and a compression chamber in a casing and a housing while fixing the casing of an opening/closing valve integrally to the outside of the housing. CONSTITUTION:A casing 14 of a first opening/closing valve 2 is fixed above an upper housing 12 while a casing 15 of an opening/closing valve 3 is fixed to the side section of a housing 7 or one side section of a housing 11. A suction path 21 and a delivery path 22 communicating with respective ports 19, 20 are formed in the upper housing 12 of the housing body 11 and the casing 14. Since piping is not required for the communication path, the space can be saved.
