Abstract: A rotor is placed on one axial side relative to a passage hole forming portion at an inside of a housing. A differential pressure device is placed on the one axial side relative to the rotor and has a pressure chamber. The housing has: a one-side space that is placed on the one axial side relative to the rotor; and at least one other-side space that is placed on another axial side, which is opposite to the one axial side, relative to the passage hole forming portion. The differential pressure device generates an urging force that urges the rotor against the passage hole forming portion by a differential pressure between a pressure in the pressure chamber and a pressure in the one-side space in a case where a pressure in the at least one other-side space is higher than the pressure in the one-side space.

Abstract: A rotating cylinder type compressor includes: a cylinder having a cylindrical shape and rotating about a central axis; a first rotor and a second rotor each having a cylindrical shape and rotating about an eccentric axis eccentric to the central axis of the cylinder; a shaft; a first vane; and a second vane. The first vane is slidably fitted to a first groove portion defined in the first rotor to define a first compression chamber. The second vane is slidably fitted to a second groove portion defined in the second rotor to define a second compression chamber. The first rotor and the second rotor are arranged in an extending direction of the central axis of the cylinder.

Abstract: A scroll-type compressor includes: a movable scroll including a low-stage movable tooth portion having a spiral shape and protruding from a first side of a movable substrate portion in an axial direction, and a high-stage movable tooth portion having a spiral shape and protruding from a second side of the movable substrate portion in the axial direction; and a shaft arranged to extend through the movable substrate portion and causing the movable scroll to undergo revolution motion. A low-stage compression mechanism and a high-stage movable compression mechanism are provided on opposite sides of the movable substrate portion in the axial direction. The numbers of curling of the low-stage movable tooth portion and the high-stage movable tooth portion are set to be one.
