Abstract: A variable displacement swash plate type compressor includes discharge passages through which refrigerant gas in a discharge passage is discharged. The discharge passages converge on downstream sides in the flowing direction of the refrigerant. A restrictor is provided in one of the discharge passages. The restrictor is used in the discharge passage to define first and second pressure monitoring points. Specifically, the first pressure monitoring point is located in the discharge passage on the upstream side of the restrictor in the flowing direction of refrigerant gas, and the second pressure monitoring point is located in the discharge passage on the downstream side of the restrictor.

Abstract: A variable displacement swash plate type compressor includes an actuator having a movable body and a control pressure chamber. An acting portion capable of pressing a swash plate by the pressure in the control pressure chamber is formed at the movable body, and an acted portion that abuts on and is pressed by the acting portion is formed at the swash plate. The acting portion abuts on the acted portion at an operative position, which moves in accordance with the change of an inclination angle of the swash plate. A top-dead-center corresponding portion is defined in the swash plate, and the operative position when the inclination angle is maximum is closer to the top-dead-center corresponding portion as compared to the operative position when the inclination angle is minimum.

Abstract: In a swash plate type variable displacement compressor, a rear housing has a pressure regulation chamber into which a rear end of a drive shaft body, a projection of a second cylinder block, a second sliding bearing, and a rear end of a second support member project. In the compressor, when a drive shaft is rotated, heat is generated in the drive shaft body, the projection, the second sliding bearing, and the second support member to heat the refrigerant gas in the pressure regulation chamber. Accordingly, in the compressor, temperature of the refrigerant gas in the pressure regulation chamber is hard to drop. Therefore, the pressure of the refrigerant gas flowing from the pressure regulation chamber to the pressure control chamber is varied quickly and a movable body is preferably moved with the pressure in the pressure control chamber.

Abstract: A double-headed piston type swash plate compressor includes a rotation shaft, a housing, a swash plate, two cylinder bores, a double-headed piston, and two shoes. The double-headed piston includes two shoe holders, a neck, two heads, and two coupling portions. Each of the coupling portions includes an outer portion and an inner portion. A direction orthogonal to both of an opposing direction of the inner portion and the outer portion and the axial direction of the double-headed piston is referred to as a widthwise direction. The neck is larger in the widthwise direction than in the opposing direction so that the neck is deformable in the opposing direction. Each of the two coupling portions has a width that is less than or equal to a width of the neck. The inner portion includes a narrow portion. The narrow portion is at least partially located closer to the head than the shoe holder in the inner portion. The two coupling portions are deformable in the widthwise direction when the swash plate applies load to the double-headed piston.

Abstract: A compressor includes an actuator that is configured to change the inclination angle of a swash plate. A movable body, which is part of the actuator, has a primary acting portion and a secondary acting portion. The swash plate has a primary receiving portion and a secondary receiving portion. When the inclination angle of the swash plate is maximized, the primary acting portion contacts the primary receiving portion to push the swash plate. When the inclination angle of the swash plate is minimized, the secondary acting portion contacts the secondary receiving portion to push the swash plate.

Abstract: In the compressor of the present invention, guide surfaces are formed on a lug plate and guided surfaces are formed on swash plate arms. The guide surfaces and the guided surfaces are respectively in linear contact with one another at a first abutment position when an inclination angle is maximum and are in linear contact with one another at a second abutment position when the inclination angle is minimum. The guide surfaces are formed such that portions between the first abutment position and the second abutment position are convex toward the guided surfaces. In the compressor, a contact angle at the first abutment position can be made large, and a contact angle at the second abutment position can be made small.
