<p>The present invention relates to a control valve capable of operating a main valve and a sub-valve by a single solenoid, and obtaining large flow when the sub-valve is opened. A control valve (1) comprises: a body (5) having a main path to connect a discharge chamber with a crank chamber, and a sub-path to connect the crank chamber with a suction chamber; a power element (6) to receive the suction pressure of a main valve prepared in the main path, a sub-valve prepared in the sub-path, and the suction chamber, and to generate a driving force in the valve opening direction of the main valve corresponding to the size of the suction pressure; and a solenoid (3) to generate a driving force in the valve closing direction of the main valve corresponding to the amount of the supplied current. Moreover, the power element (6), the main valve, the sub-valve, and the solenoid (3) are arranged in order on one end of the body (5), and a forced valve opening device to forcibly open a valve of the sub-valve by using a driving force of the solenoid (3) is provided additionally.</p> |
