Abstract

The invention provides a direction switching valve which has one inflow port and two outflow paths, is structured such as to carry out a switching of a direction (a flow path) by selectively opening and closing two outflow ports on the basis of a rotation drive source such as a stepping motor or the like, can fully open both the two outflow ports, and can achieve a speedup of a flow path switching and an energy saving. Two control valves (20A, 20B) having a pilot type valve mode are arranged between an inflow port (10) and two outflow ports (11, 12),a seesaw type oscillating arm (50) serving as an inverse drive mechanism driving the two control valves (20A, 20B) so as to open and close in an inverse direction to each other is provided between these two control valves (20A, 20B) and a stepping motor (15), and these two control valves (20A, 20B) (the outflow ports 11 and 12) can be both fully opened by stopping the seesaw type oscillating arm (50) at a specific rotational position (a horizontal position).
