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: A swash plate type variable displacement compressor according to the present invention includes a housing having a suction chamber, a discharge chamber, a swash plate chamber, and a plurality of cylinder bores, a drive shaft, a swash plate, a link mechanism, a plurality of pistons reciprocally received in the respective cylinder bores, a conversion mechanism, an actuator that changes the inclination angle of the swash plate, and a control mechanism that controls the actuator. The link mechanism disposed between the drive shaft and the swash plate allows a change in inclination angle of the swash plate with respect to a plane extending perpendicularly to the axis of rotation of the drive shaft. The conversion mechanism converts the rotation of the swash plate into reciprocal movement of the pistons in the cylinder bores with a stroke length according to the inclination angle of the swash plate.

Abstract: A swash plate type variable displacement compressor includes a collection and supply mechanism. The collection and supply mechanism has collection passages, supply passages, an annular space, an inlet port, and an outlet port. The inlet port is communicable with a working collection passage of the collection passages. The outlet port is communicable with a working supply passage of the supply passages. When the inclination angle of the swash plate is maximum, residual refrigerant gas in a compression chamber of collection phase is collected through the working collection passage and the collected refrigerant gas is supplied to a compression chamber of supply phase. On the other hand, when the inclination angle is less than the maximum, residual refrigerant gas is supplied no more into the supply-phase compression chamber.

Abstract: A compressor includes a rotary shaft, a housing in which a suction port through which a suction fluid is drawn in and a discharge port through which a compression fluid is discharged are formed, and that houses the rotary shaft, and compression chambers. The suction fluid is drawn into the compression chambers. Respective volumes of the compression chambers are periodically changed with rotation of the rotary shaft. The phases of volume changes of the compression chambers are mutually shifted. The compressor includes a communication mechanism switched between a communicating state in which the compression chambers communicate with each other, and a non-communicating state in which the compression chambers do not communicate with each other.

While the vane is moved in the axial direction with rotation of the rotors, the vane is restricted from rotating by a vane groove. The compressor includes compression chambers in which suction and compression of fluid are performed with rotation of the rotors, and a communication mechanism switched between a communicating state in which the compression chambers communicate with each other, and a non-communicating state in which the compression chambers do not communicate with each other.
