A pressure sensing member is located in the pressure sensing chamber. A pressure sensing rod is slidably supported by the valve housing. A valve body is accommodated in the valve chamber. An end of the pressure sensing rod is connected to the pressure sensing member and the other end of the pressure sensing rod contacts the valve body. A solenoid chamber is defined in the valve housing. A stationary iron core is located between the valve chamber and the solenoid chamber. A solenoid rod extends through and is slidably supported by the stationary iron core. An urging force applied to the pressure sensing member by an actuator through the solenoid rod corresponds to a target value of the pressure difference.

摘要： A control valve used for a variable displacement compressor comprises a valve housing, a valve chamber defined in the valve housing, a valve body. The valve body is located in the valve chamber. A pressure sensing chamber is defined in the valve housing. A movable wall is located in the sensing chamber to divide a first pressure chamber and a second pressure chamber. The movable wall moves in accordance with the pressure difference between the first pressure chamber and the second pressure chamber. A rod transmits the movement of the movable wall to the valve body. The pressure directed in the vicinity of the end portion of the rod is the same type pressure directed in the first pressure chamber or in the second pressure chamber. An actuator determines the target pressure difference between the two pressure chambers. This permits the displacement of the compressor to be quickly changed.

摘要： A displacement control device comprises a control valve. The control valve controls the pressure in a crank chamber. The control valve includes a valve body, and an electromagnetic actuator. A power source supplies the current to the actuator. A switch device located between the actuator and the power source. A controller determines a target value of the current supplied to the actuator in accordance with an external condition. When the target value is changed to a new value, the controller controls the switching of the switch device such that the current is intermittently supplied from the power source to the actuator before the current is set to the new target value. This permits the displacement of the compressor to be smoothly and rapidly changed.

摘要： A compressor includes a discharge chamber and a retaining passage, which is located downstream of the discharge chamber. A control valve controls the displacement of the compressor in relation to the pressure difference between a first pressure monitoring point in the discharge chamber and a second pressure monitoring point in the retaining passage. A pressure introducing passage connects the retaining passage to the control valve. The pressure introducing passage has an opening to the retaining passage. An inlet member is located in the retaining passage to cover the opening. The inlet member has a pressure introducing port that functions as the second pressure monitoring point. The pressure of the refrigerant in the retaining passage is supplied from the pressure introducing port to the control valve through the pressure introducing passage. The inlet member easily alters the position of the pressure introducing port in the retaining passage.

摘要： Compressor has a driving unit. The driving unit is provided within a crank chamber and decreases the discharge capacity when a control valve opens a control passage to increase the pressure within the crank chamber. The throttle passage delivers oil with the compressed refrigerant to the crank chamber regardless of whether the control valve has opened or closed the control passage. Because the throttle passage may continuously deliver the oil to the crank chamber even when the control valve closes the control passage, the mechanical elements within the crank chamber can be reliably and sufficiently lubricated and the crank chamber is prevented from being in an insufficiently lubricated state.
