[Problem to be solved] A control valve for a variable displacement compressor including a pressure reduction unit maintains an operation safety thereof. [Solution] A control valve (1) includes a valve driving body (30) having one end supported by a first guide hole (73) to be slid and provided with a main valve body (32) for opening and closing a main valve while contacting and separating from a main valve hole (18) and an opposite end disposed in a pressure chamber (56) and provided with a sliding part (86) supported by a second guide hole (74) to be slid; a power element (6) having one end fixed to a valve driving body (30), for detecting a suction pressure (Ps) of a suction chamber and applying a force in a valve opening direction to the valve driving body (30) if the suction pressure (Ps) is lower than a preset pressure; a transmission rod (58) operatively connected to the valve driving body (30); and a solenoid (3) for applying a solenoid force in a valve closing direction corresponding to the preset pressure to the valve driving body (30) through the transmission rod (58). |
