摘要： A valve includes: a valve housing provided with a primary pressure port and a secondary pressure port; a valve body configured to be driven by a solenoid; a valve seat on which the valve body is seated; and a spring that urges the valve body in a valve opening direction. The valve seat includes a first valve seat and a second valve seat disposed on a radially inner side of the first valve seat. The second valve seat is configured for moving in a direction toward the valve body due to a differential pressure between a primary pressure and a secondary pressure.

摘要： A capacity control valve includes a valve housing formed with a discharge port, a suction port, and first and second control ports, a rod movably arranged in the valve housing and driven by a solenoid, a CS valve configured to control a fluid flow between the first control port and the suction port in accordance with a movement of the rod, and a DC valve configured to control a fluid flow between the second control port and the discharge port in accordance with the movement of the rod. In a non-energization state, the CS valve is closed and the DC valve is closed. As the energization of the solenoid becomes larger, the CS valve transitions from a closed state to an open state and the DC valve transitions from a closed state to an open state.

摘要： A displacement control valve improved in the function of discharging a liquid refrigerant in a control chamber at startup achieves a reduction in startup time and an improvement in operating efficiency during control of a variable displacement compressor simultaneously. An opening area between a third valve section and a third valve seat surface in a control area to control the flow rate or pressure in a working control chamber is set smaller than an area of an auxiliary communicating passage, thereby reducing the minimum area of a Pc-Ps flow path in the control area.
