摘要： An electromagnetic control valve which is capable of controlling with small electromagnetic force is provided. In such electromagnetic control valve, a pressure-sensitivity control mechanism is provided in a space leading to the suction side of the compressor such that the pressure-sensitivity control mechanism faces to the crankcase pressure introducing opening of the valve main body. This pressure-sensitivity control mechanism is formed by a piston which comes into contact with the bottom surface of the valve rod. The differential pressure between the crankcase pressure and the suction pressure of the compressor is detected by the piston. Upon receipt of detection signals from a temperature sensor and a pressure sensor and an external signal, the pressure-sensitivity control mechanism adjusts the flow of refrigerant from the discharge side (high-pressure side) to the crankcase side of the compressor. Thus, the differential pressure can be controlled.

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 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： 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 CV detects a differential pressure Δt 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 CM and performs feedback control of the discharge capacity of the compressor such that the differential pressure converges to a set differential pressure. A controller 70 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 70 of a sudden change in the cooling load before the occurrence of the change or at the same time as the change occurs.

摘要： A control valve (50) controls the displacement of a variable displacement type compressor. The compressor includes a crank chamber (5), suction chamber (21), a bleed passage (27), and a supply passage (28). The control valve has a supply side valve (V2), a transmission rod (80), and a relief side valve (V1). The transmission rod (80) connects the relief side valve (V1) with the supply side valve (V2). The relief side valve (V1) includes a passage chamber (53) constituting part of the bleed passage (27). The passage chamber (53) is separated into a first area (53a), which is connected to the crank chamber (5), and a lower area (53b), which is connected to the suction chamber (21). A pressure sensing member (60) moves the relief side valve body (61) in accordance with the pressure in the upper area (53a). The effective pressure receiving area (A) of the sensing member (60) is substantially equal to the cross sectional area (B) of the passage chamber (53) that is sealed by Lhe relief side valve body (61).

摘要： A displacement control device comprises a control valve. The control valve controls the pressure in a crank chamber. The control valve includes a valve body (44), and an electromagnetic actuator (42). A power source (G) supplies the current to the actuator (42). A switch device (40) located between the actuator (42) and the power source (G). A controller (37) determines a target value of the current supplied to the actuator (42) in accordance with an external condition. When the target value is changed to a new value, the controller (37) controls the switching of the switch device such that the current is intermittently supplied from the power source to the actuator before the current is set to the new target value. This permits the displacement of the compressor to be smoothly and rapidly changed.
