摘要： A valve housing of the control valve (30) has a communication passage between the suction port (14) and the crank chamber (3) of the compressor. The control valve (30) consists of a ball valve element (38) which opens and closes according to suction pressure Ps acting on the diaphragm (45). If the suction pressure decreases below the reference pressure (Pss) the two correction springs (54,55) close the valve by moving the valve stem (40) against the valve seat (39). The spring force of the correction spring (55) is dependent on the external air temperature and consists of shape memory alloy (SMA).

摘要： A valve housing has a communication passage communicating a suction port of the compressor with a crank chamber of the compressor. A valve element opens and closes the communication passage, and a spring member resiliently biases the valve element toward the closed position. A pressure actuated unit moves the valve element toward the open position by a suction pressure of the compressor. The spring member includes a spring made of a temperature responsive material. The spring decreases in its resilient force in an opening direction of the valve element with increase of an outer-air temperature. The spring member has a primary spring made of an ordinary resilient material for resiliently biasing the valve element toward the closed position and a correction spring made of a material having a temperature positive characteristic. The correction spring provides a correction spring force smaller than a primary force of the primary spring in the opposite direction to the primary force. The combined spring force of the primary spring and the correction spring acting on the valve element.

摘要： A control valve for a variable displacement type compressor includes a movable body (43) supported by the housing (38) such that the movable body (43) moves in the housing (38). The movable body (43) includes a first valve hole (46) that forms part of a bleed passage (30). A first valve body (41) adjusts the opening of the first valve hole (46). The first valve body (41) abuts against the movable body (43) such that the first valve hole (46) is closed. A second valve hole (49) extends in the housing (38) and forms part of a supply passage (31). A second valve body (48) adjusts the opening of the second valve hole (49). The second valve body (48) is movable integrally with the movable body (43). When the movable body (43) is located at an initial position, the second valve body (48) closes the second valve hole (49). However, when the first valve body (41) separates the movable body (43) from the initial position while abutting against the movable body (43), the second valve body (48) is moved to open the second valve hole (49). In this control valve, the first valve hole (46) and the second valve hole (49) are never open at the same time. Furthermore, the control valve controls the compressor displacement with high accuracy and an responsiveness.

摘要： A variable displacement compressor the displacement of which is externally controlled is provided. A pressure sensing chamber (63) of a displacement control valve (60) is connected to a suction chamber (38) by an outlet passage (50). A bellows (66), located in the pressure sensing chamber expands and contracts in accordance with the pressure. A valve is used to control the pressure of a crank chamber (15). The valve body (72) is moved by the bellows (66) to open and close the displacement control passage (48,49). Highly pressurized gas from the discharge chamber (39) is supplied to the pressure sensing chamber (63) through an inlet passage (59). The gas in the pressure sensing chamber (63) is released to the suction chamber (38) through the outlet passage (50). An electromagnetic valve (51) is located in the outlet passage (50) to regulate the flow of refrigerant gas from the sensing chamber (63). The outlet passage (50) also includes a bypass passage (50a). The bypass passage (50a) bypasses the electromagnetic valve (51) and constantly communicates the pressure sensing chamber (63) with the suction chamber (38).
