  • Patent number: 9714646
    Abstract: A capacity control valve includes: intake-side passages connecting an intake chamber that takes in fluid and a control chamber; a pressure-sensitive chamber formed midway along the intake-side passages; a liquid-refrigerant discharge valve that receives the pressure of the control chamber to open and close the intake-side passages; a pressure-sensitive body placed in the pressure-sensitive chamber, which extends to apply a biasing force to the liquid-refrigerant discharge valve in the direction of closing the valve, while contracting as the ambient pressure increases; and a solenoid that applies an electromagnetic drive force to control the main valve; wherein the pressure-sensitive body is supported on one side by the driving rod of the solenoid in a manner permitting relative motion, while connected on the other side to the liquid-refrigerant discharge valve, wherein the discharge valve structure and discharge flow passages for discharging liquid refrigerant are simplified.

  • Patent number: 9181937
    Abstract: A displacement control valve includes an electromagnetic solenoid, a drive force transmitting body actuated, and a pressure sensitive portion having a pressure sensitive body that selectively extends and contracts in the movement direction of the drive force transmitting body in correspondence with pressure in a pressure sensitive chamber. A first valve body is arranged in the pressure sensitive body to adjust the cross-sectional area of an outlet passage. A second valve body is connected to the drive force transmitting body to adjust the cross-sectional area of a supply passage. The pressure sensitive body is movable in the movement direction of the drive force transmitting body in the pressure sensitive chamber. The pressure sensitive chamber is configured to communicate with the control pressure chamber. The pressure sensitive body is urged by the pressure in the control pressure chamber in the direction in which the first valve body closes.

  • Patent number: 9132714
    Abstract: A capacity control valve for increasing the ability to drain liquid refrigerant from a control chamber during startup of a variable-capacity compressor without changing the control valve characteristics has a spring acting in the direction of valve opening provided between an adapter and a free end of a pressure-sensitive body in the extension and contraction direction thereof and having an annular seat surface, and a third valve part having an annular engaging surface for opening and closing a suction-side passage by engaging and disengaging with the seat surface of the adapter.
