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. At least one of the two coupling portions includes a load receiving portion. The load receiving portion is configured to receive bending load that is applied from the swash plate to the double-headed piston and acts toward an inner side in the radial direction. The load receiving portion is separated from the wall surface of the cylinder bore when load applied to the double-headed piston is less than a specific threshold value. The load receiving portion abuts against the inner wall of the cylinder bore and receives the bending load when the load applied to the double-headed piston is greater than the specific threshold value.

Abstract: A variable displacement swash-plate compressor includes an actuator that changes 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 pushes the swash plate. 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 drive shaft and the acting position are viewed from a direction that is perpendicular to a top dead center plane containing the top dead center associated part and the drive shaft axis, the acting position is defined at a position overlapping with the drive shaft regardless of the inclination angle.

Abstract: A mobile body and a swash plate are coupled to each other via a columnar coupling pin provided on an outer peripheral part of the swash plate. An insertion hole through which the coupling pin is passed is formed in the swash plate. The insertion hole has a guide surface for guiding the coupling pin and for changing the inclination angle of the swash plate following movement of a mobile body to the axial direction of a rotation shaft. The guide surface has a flat surface part which is inclined to a moving direction of the mobile body. The flat surface part is set such that a perpendicular line of the flat surface part and an axial line of the rotation shaft cross in a region surrounded by a sliding part, viewed from a direction orthogonal to both an axial direction of the rotation shaft and a first direction.

Abstract: A fourth pin that slides on a rotary shaft is provided to a swash plate. A guiding surface for guiding the fourth pin is provided to the rotary shaft. The fourth pin is guided by the guiding surface, the swash plate is supported by the rotary shaft via the fourth pin, and a force having a component in a direction orthogonal to the direction of movement of a movable body acting on the swash plate is thereby reduced. Accordingly, there is a reduction in the force, which has a component in a direction orthogonal to the direction of movement of the movable body, acting on a coupling section of the movable body via a third pin from the swash plate. As a result, when the inclination of the swash plate is changed, unwanted tilting of the movable body relative to the direction of movement is suppressed.

Abstract: The valve body has a first valve part and a second valve part. The first valve part has an end surface seal part that is brought into contact with a seat part of a first valve seat part and closes a bleed passage. The second valve part has an external surface seal part that enters the second valve hole and closes the supply passage. When the opening degree of the first valve part is maximum, the seal length of the external surface seal part along the moving direction of the valve body is shorter than the distance between the end surface seal part and the seat part along the moving direction of the valve body.

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.
