<p>A control valve includes a common body (504), a valve element (541) for regulating the opening degree of a proportional valve (51) by moving toward and away from a valve hole (520), a valve element (533), having a valve hole (528), for opening and closing a valve (571) by moving toward and away from a valve hole (524), a valve element (542) for regulating the opening degree of a valve (572) by moving toward and away from the valve hole (528), the valve element (542) being provided in such a manner as to be integrally displaceable relative to the valve element (541), springs (544), which biases the valve element (533) in a valve closing direction of the valve (571) and in an opening direction of the valve (572), and structured such that the valve (571) functions as a check valve, a motor unit (102) for electrically controlling the opening degrees of the first proportional valve (51), the valve (571) and the valve (572), and a valve actuating member (134) for transmitting the drive force, which acts in opening and closing directions of each valve, to the valve element (541), the valve actuating member (134) being driven by the motor unit (102) in a direction of axis line.</p> |
