  • Patent number: 9228576
    Abstract: A compressor includes an actuator. The actuator is arranged in a swash plate chamber, while being rotational integrally with a drive shaft. With reference to the swash plate, the actuator is located in a region in which a first cylinder bore is located. The actuator includes a rotation body fixed to the drive shaft, a movable body, and a control pressure chamber. A link mechanism is located between the drive shaft and the swash plate. As the inclination angle of the swash plate is changed, the link mechanism moves the top dead center position of a first head by a greater amount than the top dead center position of a second head.

  • Publication number: 20150285234
    Abstract: A swash plate type variable displacement compressor includes a housing in which a suction chamber, a discharge chamber, a swash plate chamber, and a cylinder bore are formed, a drive shaft, a swash plate, an actuator, and a control mechanism that controls the actuator. A pressure regulation chamber is formed in the housing. The actuator includes a control pressure chamber. The control mechanism includes a control passage that connects together the discharge chamber, the pressure regulation chamber, and the control pressure chamber, and a control valve that, by adjusting the degree of opening of the control passage, changes the pressure in the control pressure chamber to allow the movable body to move. Refrigerant in the discharge chamber flows into the control pressure chamber via the pressure regulation chamber. The pressure regulation chamber functions as a muffler that reduces the pulsation of the refrigerant.

    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.

  • Publication number: 20150260175
    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.
