摘要： A control valve includes: a first valve to control a flow rate of refrigerant flowing from a discharge chamber to a control chamber of a compressor; a second valve to control a flow rate of the refrigerant flowing from the control chamber to a suction chamber; a solenoid to generate a drive force in a first valve closing direction and a second valve opening direction; a biasing member to generate a biasing force in an first valve opening direction and a second valve closing direction; and a pressure sensing part to sense a pressure in the suction chamber or the control chamber, and generate a counterforce against the drive force. A state in which both of the first and second valves are open is present during an increase in the current supplied to the solenoid from zero to an upper limit current value, and an increase rate of an opening degree of the first valve is increased during a decrease in the current supplied to the solenoid, a predetermined lower limit current value being an inflection point of the increase.

摘要： A control valve is configured such that a suction pressure, which is used to displace a sub-valve element in a valve opening direction after a main valve has been closed, is varied according to a value of current supplied to a solenoid. A crankcase communication port, which communicates with a crankcase of a compressor, and a suction chamber communication port, which communicates with a suction chamber of the compressor, are provided in a body. A sub-valve chamber whose diameter is larger than that of the main valve hole is formed between the crankcase communication port and a main valve hole, and a sub-valve is placed in the sub-valve chamber.

摘要： In a control valve, the spring load of a spring, which biases a main valve element in a valve opening direction, is regulated, for instance. This allows a range of suction pressures Ps, where a main valve and a sub-valve are simultaneously closed until a sub-valve element is lifted from a sub-valve seat after a main valve element has been seated on a main valve seat, to be set as a deadband. The control valve is configured such that the value of a suction pressure Ps with which to open the sub-valve after the closing of the main valve and the pressure values at which the deadband takes place are set variably by the setting of a value of current supplied to the solenoid.
