<P>PROBLEM TO BE SOLVED: To provide a directional control valve performing a quick and energy-saving switching of a flow path, the valve which has one inlet and two outlets, switches a direction (flow path) by opening and closing the two outlets selectively by a rotary driving source such as a stepping motor, and also can fully open both of the two outlets. <P>SOLUTION: The two control valves 20A and 20B having a pilot type valve shape are arranged between the inlet 10 and the two outlets 11 and 12, and a see-saw type swinging arm 50 are equipped between the two control valves 20A and 20B, and a stepping motor, as a reverse driving mechanism driving the two control valves 20A and 20B to be opened and closed mutually reversely. Both of the two control valves 20A and 20B (outlets 11 and 12) can be fully opened when the see-saw type swinging arm 50 is stopped in a specified turning position (horizontal position). <P>COPYRIGHT: (C)2013,JPO&INPIT |
