    摘要: A displacement control valve for a variable displacement compressor. The displacement control valve includes a drive force transmission body, a pressure sensitive chamber, an internal passage, and a valve body. The valve body includes an annular seal which is contactable with a valve seat surface facing toward the first valve body. The drive force transmission body includes a drive rod and a valve body structure having a shaft passage and forming the first valve body. The drive rod is fitted to the shaft passage and coupled to the valve body structure so as to form a gap passage between an outer surface of the drive rod and a wall surface of the shaft passage. The internal passage includes a recess arranged radially inward from the annular seal, the shaft passage, and the gap passage. The gap passage is in direct communication with the recess.

    摘要: 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.

    摘要: A capacity control valve in which a valve opening degree can be favorably adjusted is provided. A capacity control valve includes a valve housing (10) provided with a suction port (11) through which a suction fluid of suction pressure (Ps) passes, and a control port (12) through which a control fluid of control pressure (Pc) passes, a valve element (51) configured to be driven by a solenoid (80), a spring (85) that biases the valve element (51) in the direction opposite to the driving direction by the solenoid (80), and a CS valve (50) formed by a CS valve seat (10a) and the valve element (51) and configured for opening and closing a communication between the control port (12) and the suction port (11) by movement of the valve element (51). The control pressure (Pc) is controlled by opening and closing the CS valve (50), and the capacity control valve further includes a pressure receiving portion (51d) to which force in accordance with discharge pressure (Pd) is applied in the axial direction of the valve element (51) .

    摘要: The object of the present invention is to significantly improve a function for discharging a liquid refrigerant in a control chamber at the time of start-up of a variable capacity compressor by moving a center post and increasing the area of a passage for discharging the liquid refrigerant when discharging the liquid refrigerant.
    The present invention is characterized by including: a first valve chamber formed in the middle of the discharge-side passages 31, 32, 33; suction-side passages for providing communication between a suction chamber for sucking the fluid and the control chamber; a second valve chamber 36 and a third valve chamber 38 formed in the middle of the suction-side passages; a solenoid 60 for exerting an electromagnetic driving force for controlling a valving element 40, and in which a suction-side passage opening/closing means has a third valve portion 43 for opening and closing the suction-side passages 33, 32, 34 by receiving the pressure of the control chamber in the third valve chamber 38, and a second valve portion 42 for opening and closing the suction-side passages by receiving the electromagnetic driving force in the second valve chamber 36, and a center post 64 which is a constituent member of the solenoid is provided movably in the axial direction in such a manner that one end face thereof is opposed to the second valve portion 42, and the center post 64 is driven to the direction away from the second valve portion 42 and controlled so that the distance between the second valve portion 42 is increased when discharging the liquid refrigerant.
