摘要： A motor operated valve includes a feed screw mechanism and a stopper mechanism. The feed screw mechanism includes a guiding part including an external thread portion on an outer surface thereof, and a guided part that is a cylindrical member constituting a rotation shaft of a rotor, and including an internal thread portion, which is engaged with the external thread portion, on an inner surface thereof. The stopper mechanism includes a stopper portion provided on the guided part, and a stopping face formed integrally with the guiding part. When a valve element is driven by the motor to move in a valve closing direction, the stopping face stops the stopper portion to restrict the movement of the rotor in the valve closing direction.

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.

摘要： A control valve according to an exemplary embodiment includes an interlocking mechanism that achieves a first operation and a second operation simultaneously or continuously. In the first operation, a sub-valve is opened by having an actuating rod displaced integrally with a sub-valve element in accordance with the magnitude of solenoidal force. In the second operation, a load, by which to bias a main valve element in a closing direction of a main valve, is increased by displacing the actuating rod relative to the main valve element.
