<P>PROBLEM TO BE SOLVED: To easily and inexpensively achieve a control valve capable of securing a blocking function of working fluid when not operated and capable of adjusting flowing quantity of the working fluid when operated. <P>SOLUTION: The control valve 50 has a motor 130 attached to a body 70, a valve body 106 adjusting the opening of the valve part, an operating rod 134 supporting the valve body 106 in an axial direction, a drive unit 102 arranged between the motor 130 and the operating rod 134, converting the rotation force of the motor 130 to the parallel advancing force in the axial direction of the operating rod 134, and transmitting driving force in an opening/closing direction to the valve body 106 via the operating rod 134, and a spring 114 biasing the valve body 106 in a valve closing direction. The drive unit 102 receives the biasing force of the spring 114 via the valve body 106 and the operating rod 134 and thereby moves in a direction allowing the operating rod 134 to move in the valve closing direction, in the case the energization to the motor 130 is blocked when opening the valve body 106. <P>COPYRIGHT: (C)2013,JPO&INPIT |
