摘要： An object of the present invention is to promote oil separation in a sealed container, thereby decreasing the amount of oil discharged to the outside of a compressor. The compressor comprises discharge hole provided at position facing the end surface of a rotor and through which a compressed refrigerant from first and second rotary compression elements is discharged into the sealed container; and a refrigerant flow path which is extended from a space surrounded with a coil end of a stator projecting from the end surface of the rotor to a rotary compression mechanism side to a space of an air gap between the rotor and the stator, to guide the compressed refrigerant discharged through the discharge hole to an electromotive element opposite to the rotary compression mechanism side. The outlet of this refrigerant flow path opposite to the rotary compression mechanism side faces the inner wall surface of the sealed container, and the volume of a space between the inner wall surface of the sealed container and the electromotive element is 1.5 times or more and 15 times or less that of a space between the rotary compression element and the electromotive element.

摘要： 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.
