Abstract: In the compressor of the present invention, a throttle hole is formed in a connection portion. The throttle hole extends from a control pressure chamber toward the inside of an outer sliding portion. In the compressor, when the pressure in the control pressure chamber is regulated, in addition to respective opening degree adjustments of a high-pressure passage and a low-pressure control valve, a refrigerant gas is discharged from the inside of the control pressure chamber to a swash plate chamber through the throttle hole. Lubricant is discharged from the throttle hole together with the refrigerant gas. Consequently, in the compressor, the lubricant is less easily stored in the control pressure chamber, and lubricant shortage in the swash plate chamber less easily occurs.

Abstract: In a compressor that changes a discharge capacity by using an actuator, a variable displacement swash plate type compressor capable of realizing reduction in manufacture cost is provided.In the compressor of the present invention, a ring groove is formed in a movable body, and the ring groove is provided with an annular member. The annular member has a joint gap formed by a first to a third cutouts, and the third cutout is an aperture. In this compressor, the annular member moves in the ring groove based on a pressure difference between a control pressure chamber and a swash plate chamber. Thereby, in the compressor, a pressure in the control pressure chamber is regulated by regulating a flow of a refrigerant that flows to the swash plate chamber from the control pressure chamber.

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: A variable displacement swash-plate compressor includes an actuator that is configured to change the inclination angle of a swash plate. The actuator includes a movable body that moves along a drive shaft axis. The movable body includes an acting portion that is configured to push the swash plate with the pressure in a control pressure chamber. The swash plate includes a receiving portion that contacts and is pushed by the acting portion. The acting portion and the receiving portion contact each other at an acting position. A bottom dead center associated part for positioning the piston at a bottom dead center is defined on the swash plate. When the inclination angle is minimized, the acting position is located at a position closer to the bottom dead center associated part than the drive shaft axis.

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.

Abstract: In a swash plate type variable displacement compressor, a lug plate includes a cylinder chamber and first and second guide surfaces. Inner peripheral edges of the first and second guide surfaces are defined respectively at parts where the peripheral edge of the cylinder chamber and the guide surfaces overlap with each other. When the inclination angle of a swash plate of the compressor is maximum, first and second guided surfaces and the first and second guide surfaces, respectively are brought into line contact with each other at a first position. At this time, first and second slide contact widths are maximum. When the inclination angle of the swash plate is minimum, the first and second guided surfaces and the first and second guide surfaces, respectively are brought into line contact with each other at a second position. At this time, the first and second slide contact widths are minimum.
