A multi-rotor type compressor (5) including plural compression elements each of which includes a rotor (77,79) eccentrically rotating in a cylinder (69,70) and a vane which is in sliding contact with the outer peripheral surface of the rotor and partitions the inside space of the cylinder into a suck-in space in which a suck-in operation is performed and a compression space in which a compressing operation is performed, and a power save mechanism including an intercommunication path (83) through which the compression space of a compression element is allowed to intercommunicate with the suck-in space of another compression element at a predetermined phase, an interception valve (85,87,89) for intercepting flow of fluid in the intercommunication path, and a check valve (98,99) which is provided in the intercommunication path and allows the fluid to flow therethrough in only one direction. The compression may be equipped in an air conditioner. In addition to the power save mechanism may be provided a compression stop mechanism for stopping a prescribed compression operation to reduce a part of the entire compression work of the compressor. <IMAGE> <IMAGE> |
