Abstract: A variable displacement swash compressor includes a housing, a drive shaft, a swash plate, a link mechanism, a piston, a conversion mechanism, an actuator, and a control mechanism. The swash plate is rotatable together with the drive shaft in a swash plate chamber. The conversion mechanism reciprocates the piston in a cylinder bore. The actuator is operative to change the inclination angle of the swash plate. The actuator is rotatable integrally with the drive shaft. The actuator includes a partitioning body, a movable body, and a control pressure chamber. The control mechanism changes the pressure of the control pressure chamber to move the movable body. The movable body and the link mechanism are located at opposite sides of the swash plate.

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: 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.

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.

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.

Abstract: A compressor includes two rotors opposed to each other in an axial direction, and a vane contacting the rotors. 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.
