切換弁。 A pair of electromagnetically driven pilot valves 13, 14
In a pilot type directional control valve in which the main valve 2 is switched between a plurality of positions by opening/closing control, and the direction of fluid supply is switched by this switching arrangement, a pair of plungers 7, 9 connected to the pair of pilot valves 13, 14 are provided. A shift mechanism 21, 21a, 22, 23 is provided with a pair of cam portions 21b, 21c for switching between a locked position and an unlocked position of the pilot valves 13, 14, and both plungers 7, 9 are provided. The cam action relationship between both cam portions 21b and 21c provides a first cam action that switches both plungers to the unlocked position, and second and third cam actions that switch only one plunger to the locked position.
The switching lever 21a is set between the two cam portions 21b and 21 and is operated to switch to three switching positions P 0 , P 1 , and P 2 that provide the first to third cam actions.
A pilot type directional control valve characterized in that it is connected to c.
