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: Provided is a compressor, in which the inclination angle of a swash plate is changed by an actuator, ensuring stability on a product-by-product basis while realizing reduction in size. In the compressor, when pressure in a control pressure chamber increases, a movable body moves toward a flange. At this time, the movable body pulls the opposite end side of a swash plate rearward in a swash plate chamber via first and second pulling arms. A link mechanism permits increase of the inclination angle of the swash plate until reaching a maximum value. When the pressure in the control pressure chamber reaches a required control pressure, a rear wall of the movable body which has moved rearward in the swash plate chamber abuts a front face of the flange. This makes it possible in this compressor to restrict the maximum value of the inclination angle of the swash plate.

Abstract: A variable displacement swash plate type compressor includes a rotary shaft, a swash plate, and an actuator, which changes the inclination angle of the swash plate. The actuator includes a partition body and a movable body, which moves in a direction along the rotational axis of the rotary shaft. The movable body includes a guide surface, which changes the inclination angle of the swash plate, and a sliding portion, which slides on the rotary shaft or on the partition body. When viewed from a direction that is perpendicular to the direction in which the rotational axis of the rotary shaft extends and perpendicular to a first direction, the guide surface is configured such that a perpendicular line or a normal line to the guide surface intersects with the rotational axis of the rotary shaft in a zone surrounded by the sliding portion.

Abstract: An inclination angle of a swash plate of a swash plate type variable displacement compressor is rapidly changed to the maximum when electric current is supplied to an electromagnetic solenoid and therefore the compressor is operated at the maximum displacement. When a second valve body is opened, a first valve body is closed; when the second valve body is closed, a valve opening of the first valve body is controlled. Under the circumstance that electric current is supplied to the electromagnetic solenoid and an instruction for operating the compressor at the maximum displacement is issued, when the first valve body is closed, the second valve body is opened. In addition to supply of refrigerant gas from a discharge chamber to a control pressure chamber through a first supply passage, refrigerant gas is supplied from the discharge chamber to the control pressure chamber through a second supply passage.
