摘要： A control valve controls the displacement of a variable displacement compressor. The control valve includes a first valve body for adjusting the pressure in a crank chamber, a pressure sensing member, which is displaced in accordance with the pressure difference between two pressure points located in a refrigerant circuit to move the first valve body, an electromagnetic actuator for urging the pressure sensing member, and a second valve body, which is operably coupled to the pressure sensing member. The second valve body adjusts the opening degree of a discharge passage of the refrigerant circuit in accordance with the displacement of the pressure sensing member. Therefore, compared to a case where the first and second valve bodies are independently arranged in the compressor, the number of parts are reduced, which reduces the manufacturing cost.

摘要： A torque limiting mechanism for transmitting power from an external drive source to the drive shat of a compressor. A pulley, which is coupled to the external drive source, has elastic members. A hub, which is attached to the drive shaft, has engaging portions. A coupler member is located between the pulley and the hub. The coupler member is engaged with the elastic members and with the engaging portions such that power is transmitted from the pulley to the hub. The urging members urge the coupler member such that the coupler member is disengaged from the engaging portions. When power is transmitted from the pulley to the hub, the elastic members maintain the coupler engaged with the elastic members and the engaging portions. When load generated due to power transmission exceeds a predetermined level, the elastic members are deformed such that the coupler member is disengaged from the elastic members. When disengaged from the elastic members, the coupler member is disengaged from the engaging portions.

摘要： An electromagnetic displacement control valve in a clutchless type variable displacement compressor is disclosed. The control valve includes a valve body, an electromagnetic driving device, a buffer spring, and an urging spring. The electromagnetic driving device drives the valve body toward a position for closing the valve hole. The buffer spring urges the valve body toward the position for closing the valve hole. The urging spring urges the valve body in a direction away from the position for closing the valve hole against an elastic urging force of the buffer spring. In a state where no current is supplied to the electromagnetic driving device, the valve body is capable of moving in a direction away from the position for closing the valve hole against the elastic urging force of the buffer spring.

摘要： A control valve for a clutch type variable displacement compressor includes a liquid-discharge passage for connecting a second port in communication with a control-pressure chamber of the compressor to a third port in communication with the suction-pressure region of the compressor. Opening and closing the liquid-discharge passage are controlled by movement of a pressure-sensing member of a pressure-sensing mechanism. The pressure-sensing member is placed such that the liquid-discharge passage is opened while pressure equalization inside the compressor at a stop of the compressor is maintained in starting the compressor from its stop state. The pressure-sensing member is moved in a direction which causes the liquid-discharge passage to be closed when a pressure in the suction-pressure region is lowered and reaches a predetermined pressure as the compressor is started.

摘要： A displacement control valve includes a reciprocation body which has a valve body. The reciprocation body includes a first shaft portion that has the valve body and a second shaft portion that is coaxial with the first shaft portion and inserted in a valve hole. The first shaft portion is located adjacent to a solenoid. The second shaft portion is connected to a pressure sensing mechanism. The second shaft portion and the valve hole define a flow path in which refrigerant freely flows. A throttle portion is formed between the first and second shaft portions and coaxial with the first and second shaft portions. Diameter of an end of the throttle portion adjacent to the second shaft portion is set larger than that of the second shaft portion adjacent to the throttle. Flow rate of the refrigerant in the flow path is suppressed by the throttle portion.

摘要： A displacement control valve for a variable displacement compressor includes a valve hole partially forming a supply passage or a bleed passage of the compressor and a valve body having a cross-sectional area changed portion that is movable into and out of the valve hole. The cross-sectional area changed portion has a minimum cross-sectional area portion and a maximum cross-sectional area portion. The cross-sectional area changed portion is shaped so that the cross-sectional area of the cross-sectional area changed portion increases from the minimum cross-sectional area portion to the maximum cross-sectional area portion. The minimum cross-sectional area portion initially enters into the valve hole when the cross-sectional area changed portion is moved into the valve hole. The maximum cross-sectional area portion is movable into the valve hole. The valve hole is closed when the maximum cross-sectional area portion is positioned in the valve hole.
