摘要： A valve housing of the control valve has a communication passage communicating a suction port of the compressor with a crank chamber of the compressor. A main valve is provided in the valve housing for opening and closing the communication passage. A spring member resiliently biases the main valve toward its closed position. A pressure actuated unit moves the main valve toward the open position by receiving a suction pressure of the compressor. A flow adjustment valve is disposed in the valve housing for adjusting an open degree of a leak passage and receives the discharge pressure exerting a force on the flow adjustment valve toward its closed position. The flow adjustment valve increases a leak flow rate of a fluid flowing from a discharge port of the compressor to a crank chamber through a leak passage when the compressor provides a lower discharge pressure. A correction spring is disposed between the main valve and the flow adjustment valve. The correction spring resiliently biases a valve element of the main valve toward the open position and increases in spring force with transfer of a valve element of the flow adjustment valve toward its closed position.

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.

First and second pressure monitoring points are located in a refrigerant circuit. The first pressure chamber is exposed to the pressure at the first pressure monitoring point. The second pressure chamber is exposed to the pressure at the second pressure monitoring point. The ball is displaced based on the pressure difference between the first pressure chamber and the second pressure chamber.

摘要： A variable displacement compressor has a housing, a drive shaft, a rotor, a swash plate, a piston and a decelerating mechanism. The housing includes a cylinder bore and supports the drive shaft. The rotor is secured to the drive shaft. The swash plate is operatively connected to the rotor and the drive shaft so as to rotate therewith and varies its inclination angle relative to the drive shaft. The piston is connected to the swash plate so as to reciprocate in the cylinder bore with rotation of the swash plate. A stroke of the piston varies in accordance with the inclination angle of the swash plate. The deceleration mechanism between the rotor and the swash plate decelerates the inclination speed of the swash plate in a range from a near maximum inclination angle to the maximum inclination angle when the swash plate inclines to increase the stroke of the piston.

摘要： A first bleed passage and a second bleed passage each connect a crank chamber of a compressor with a suction chamber of the compressor. A first supply passage and a second supply passage each connect the crank chamber with a discharge chamber of the compressor. A first control valve adjusts the opening size of the first supply passage in response to the pressure in the suction chamber. A second control valve includes a ball valve and an electromagnetic actuator. The ball valve adjusts the opening size of the second supply passage and the opening size of the first bleed passage. The electromagnetic actuator moves the ball valve. The ball valve is moved to a first position and to a second position. At the first position, the ball valve closes the second supply passage and opens the first bleed passage. At the second position, the ball valve opens the second supply passage and closes the first bleed passage. A displacement control device, which includes the first and second control valves, readily and reliably changes the displacement of the compressor.

摘要： A control apparatus that promptly increases the displacement of a compressor after the compressor is started while liquefied refrigerant is lingering in an external circuit. The control apparatus includes a restricting passage. The restricting passage is located in a first pressure introduction passage, through which the pressure of the first pressure monitoring point flows to the control valve. The restricting passage decreases the pressure of refrigerant that flows through the passage. When the compressor is started while liquefied refrigerant is lingering in the external circuit and the pressure of the first pressure monitoring point is abruptly increased, the restricting passage reduces the increase of the pressure that is detected by the control valve. Therefore, the displacement of the compressor is promptly increased.
