    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 control valve of a variable displacement compressor is disclosed. The control valve includes a valve housing, a valve body, a valve opening spring, an electromagnetic actuator, and an urging plate. The valve housing has a valve chamber that forms a part of a supply passage. The valve body can selectively contact and separate from a valve seat in the valve chamber. The valve opening spring urges the valve body away from the valve seat. The electromagnetic actuator changes electromagnetic urging force acting on the movable iron core through control of externally supplied current. In a state where the electromagnetic actuator is not energized and the valve body is held at a position separated from the valve seat by the urging force of the valve opening spring, the urging plate deforms in such a manner as to urge the valve body toward the valve seat when the temperature of the urging plate reaches a predetermined temperature. The urging force of the urging plate when the temperature reaches the predetermined temperature is set to be greater than the urging force of the valve opening spring in a state where the electromagnetic actuator is not energized.

    摘要： A control valve used in a variable displacement compressor includes a valve chamber (46), a valve body (43) and a pressure sensing chamber (48). A pressure sensing ball is movably located in the pressure sensing chamber (48) and divides the pressure sensing chamber (48) into a first pressure chamber (55) and a second pressure chamber (56). First and second pressure monitoring points (P1, P2) are located in a refrigerant circuit. The first pressure chamber (55) is exposed to the pressure at the first pressure monitoring point (P1). The second pressure chamber (56) is exposed to the pressure at the second pressure monitoring point (P2). The ball is displaced based on the pressure difference between the first pressure chamber (55) and the second pressure chamber (56). The position of the valve body (43) is determined based on the position of the pressure sensing member (54).

    摘要： An object of the capacity control valve (1) is to provide a constant, stable control of the pressure load without fluctuations. Also another object is to improve an energy efficiency of the drive torque of the rotary shaft by means of a control of the pressure load. In this arrangement, the solenoid coil section (S) controls as a reference value of pressure load which is calculated by taking a sum of a pressure differential between the discharge pressure (Pd) and the pressure in the control chamber (Pc), multiplied by the area (S1) of the open passage of the first valve seat (10), and a pressure differential between the pressure in the control chamber (Pc) and the suction pressure (Ps), multiplied by the area (S2) of the open passage of the second valve seat (11).
