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 drive-shaft-parallel line segment is defined that contains the acting position and connects a proximal end of the acting portion and a proximal end of the receiving portion to each other, while extending in parallel with the drive shaft axis. The drive-shaft-parallel line segment is shorter when the inclination angle of the swash plate is maximized than when the inclination angle is minimized.

Abstract: Provided is a compressor, in which discharge capacity is changed by an actuator, exhibiting high controllability while realizing reduction in size. In the compressor, a movable body includes a rear wall, a circumferential wall, and a coupling mechanism. The coupling mechanism includes a first arm provided with a first pulling point and a second arm provided with a second pulling point. In the compressor, when the inclination angle of a swash plate is increased, the movable body pulls the swash plate via the first and second arms. At this time, in the compressor, pulling force can be applied at two points, i.e., at the first pulling point and the second pulling point. Consequently, in the compressor, even when the size of the rear wall and the circumferential wall is increased, the rigidity of the first and second arms can be made lower.

Abstract: A variable displacement swash plate compressor includes a control pressure chamber and a displacement control valve that controls the pressure of the control pressure chamber. The displacement control valve includes an electromagnetic solenoid, a driving force transmission member, a valve body, and a pressure sensing mechanism. An accommodation chamber accommodates the pressure sensing. A valve chamber accommodates the valve body having a valve opening degree determined by an urging force applied to the valve body through the driving force transmission member and by an urging force applied to the valve body by the expansion and contraction of the pressure sensing mechanism. The valve body and the pressure sensing mechanism form a valve unit. When the electromagnetic solenoid is deactivated, the pressure of the accommodation chamber acts on a back surface of the pressure sensing mechanism so that a force in the open direction is applied to the valve unit.

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.
