摘要： A control valve is located in a variable displacement compressor used in a refrigerant circuit. The control valve operates such that the pressure difference between two pressure monitoring points in the refrigerant circuit seeks a predetermined target value. A controller determines the target value of the pressure difference in accordance with external information that represents the required cooling performance. The target value of the pressure difference is represented by a duty ratio applied to the control valve. When the acceleration pedal is pressed beyond a predetermined level, the controller limits the duty ratio. Therefore, the compressor torque does not hinder quick vehicle acceleration. Also, the cooling performance is not lowered unless it is necessary.

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 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.

摘要： A control valve is located in a variable displacement compressor that is installed in a refrigerant circuit. The control valve operates such that the pressure difference between first and second pressure monitoring points in the refrigerant circuit seeks a predetermined target value. The first pressure monitoring point is located in a discharge chamber of the compressor. The second pressure monitoring point is located in a flow pipe that extends from the discharge chamber. The static pressure of refrigerant in the discharge chamber is introduced into a control valve from the first pressure monitoring point. A pressure that includes the static pressure and the dynamic pressure of refrigerant in the flow pipe is introduced into the control valve from the second pressure monitoring point. As a result, the displacement of the compressor is reliably controlled without being affected by the thermal load of an evaporator.

摘要： A control valve is located in a variable displacement compressor incorporated in a refrigerant circuit. The control valve controls the displacement of the compressor in accordance with a pressure difference between a first pressure monitoring point and a second pressure monitoring point, which are located in the refrigerant circuit, such that the pressure difference seeks a predetermined target value. An adjusting valve, which is a variable throttle valve, is located in a section of the refrigerant circuit between the first and second pressure monitoring points. The adjusting valve adjusts the restriction amount of the refrigerant in relation to the refrigerant flow in the refrigerant circuit. The compressor displacement is thus optimally controlled.

摘要： A valve body adjusts opening of a supply passage in response to the position in a valve chamber. A pressure-sensitive member is moved in accordance with the pressure difference between two pressure monitoring points, which are located in an external refrigerant circuit. The movement of the pressure-sensitive member affects the position of the valve body such that the compressor displacement is changed to reduce fluctuations in the pressure difference. A solenoid changes force applied to the valve body so that a set pressure difference, which is a reference value for changing the position of the valve body by the pressure-sensitive member, is changed.

摘要： An air-conditioning system with a refrigerant circulation circuit, which has improved control precision for maintaining a compartment temperature and improved response characteristics. The refrigerant circulation circuit includes a variable displacement type compressor, the discharge capacity of which is controlled by a control valve. The control valve detects a differential pressure between two pressure monitoring points in the refrigerant circulation circuit as an index for estimating the refrigerant discharge capacity of the variable displacement type compressor and performs feedback control of the discharge capacity of the compressor such that the differential pressure converges to a set differential pressure. A controller determines or recomputes the set differential pressure based on information from a mode switching unit or an air-flow-rate switch and instructs the control valve to change the set differential pressure accordingly. The switch information from the mode switching unit or the air-flow-rate switch signals the controller of a sudden change in the cooling load before the occurrence of the change or at the same time as the change occurs.
