ABSTRACT:
In a multicylindrical rotary compressor constituted to be usable by urging an only first vane with respect to a first roller by means of a spring member to switch a first operation mode in which first and second rotary compression elements perform compression works and a second operation mode in which substantially the only first rotary compression element performs the compression work, an object is to reduce generation of collision noises due to collision of the second vane with the second roller at a time when the first operation mode is switched to the second operation mode, and a pressure in a back-pressure chamber of the second vane is discharged on a low-pressure chamber side in a second cylinder in a case where the first operation mode is switched to the second operation mode.
