摘要： A control valve (CV) is located in a variable displacement compressor that is installed in a refrigerant circuit. The control valve (CV) operates such that the pressure difference between first and second pressure monitoring points (P1, P2) in the refrigerant circuit seeks a predetermined target value. The first pressure monitoring point (P1) is located in a discharge chamber (22) of the compressor. The second pressure monitoring point (P2) is located in a flow pipe (36) that extends from the discharge chamber (22). The static pressure of refrigerant in the discharge chamber is introduced into a control valve (CV) from the first pressure monitoring point (P1). A pressure that includes the static pressure and the dynamic pressure of refrigerant in the flow pipe (36) is introduced into the control valve (CV) from the second pressure monitoring point (P2) . As a result, the displacement of the compressor is reliably controlled without being affected by the thermal load of an evaporator (33).

摘要： A control valve (46) is located in a variable displacement compressor used in a refrigerant circuit. The control valve (46) operates such that the pressure difference (PdH-PdL) between two pressure monitoring points (P1, P2) in the refrigerant circuit seeks a predetermined target value. A controller (81) determines the target value of the pressure difference (Pdh-PdL) in accordance with external information that represents a required cooling performance of the refrigerant circuit. The target value of the pressure difference (PdH-PdL) is represented by the duty ratio of voltage applied to the control valve (46). When the depression degree of the acceleration pedal is greater than a predetermined level, the controller (81) sets a limit value of the duty ratio. The controller (81) changes the duty ratio to the limit value to limit the compressor displacement only when the limit value is set and the duty ratio is greater than the limit value. Therefore, the compressor torque does not hinder quick acceleration of the vehicle. Also, the occasions in which the cooling performance is lowered below a demanded level are minimized while preventing the compressor torque from hindering quick accelerations of the vehicle.

摘要： L'invention concerne une soupape de commande de déplacement (49) améliorée intégrée dans un compresseur à déplacement variable. La soupape de commande (49) comporte un corps de soupape (54) et un solénoïde (52) permettant d'actionner le corps de soupape (54). La bobine (92) du solénoïde (52) est enroulée autour d'une armature de bobine réalisée en résine synthétique isolante. Une plaque de base fait saillie à partir de l'armature de bobine (92). Une paire de plaques conductrices est fixée sur la plaque de base. Chaque plaque présente un bloc de serrage. La bobine présente une paire de fils terminaux. Chaque fil terminal est fixé sur et connecté électriquement à l'un des blocs de serrage. Chaque fil terminal est enroulé autour d'un support formé dans chaque plaque entre l'armature de bobine et le bloc de serrage correspondant. Une diode est fixée sur les supports et est connectée en parallèle à la bobine. Une paire de bornes de la diode est fixée sur les supports correspondants par brasage et sertissage. Les supports empêchent la tension existant dans les fils terminaux d'être appliquée aux jonctions électriques formées entre les fils et les blocs de serrage, ce qui rend la soupape plus fiable.

摘要： A control valve for a variable capacity compressor is provided with a ball valve element 37 to open or shut communication passages (32, 34, 33) for communicating a suction port of a compressor to a crank chamber. The ball valve element 37 is energized to move in a valve shutting direction by a spring force of a compression coil spring 44. The control valve for a variable capacity compressor is provided with a bellows device 40, which drives the ball valve element 37 to move in a valve opening direction being affected by a suction pressure of the compressor. The ball valve element 37 is directly connected to the bellows device 40 with utilizing the ball valve element 37 as an automatic centripetal ball. A valve housing 31 is provided with a hollow tube 49 for introducing a delivery pressure, which is joined to the ball valve element 37 at an end thereof and directly exerts the delivery pressure of the compressor on the ball valve element 37 to move in a valve opening direction. A compression coil spring 50 energizes the ball valve element 37 to move in a valve opening direction through the hollow tube 49 for introducing the delivery pressure.

摘要： A control valve used for a variable displacement compressor comprises a valve housing (45), a valve chamber (46) defined in the valve housing (45), a valve body (43). The valve body (43) is located in the valve chamber (46). A pressure sensing chamber (48) is defined in the valve housing (45). A movable wall (54) is located in the sensing chamber (48) to divide a first pressure chamber (55) and a second pressure chamber (56). The movable wall (54) moves in accordance with the pressure difference between the first pressure chamber (55) and the second pressure chamber (56). A rod (40) transmits the movement of the movable wall (54) to the valve body (43). The pressure directed in the vicinity of the end portion of the rod (40) is the same type pressure directed in the first pressure chamber (55) or in the second pressure chamber (56). An actuator determines the target pressure difference between the two pressure chambers. This permits the displacement of the compressor to be quickly changed.
