プールをパイロツト圧の作用で切換える方向制御
弁において、上記スプール両端を、上記弁本体に
形成のタンク通路に連通させた作用室に臨ませる
一方、この作用室に隣接してパイロツト室を設け
るとともに、摺動自在にしたプランジヤの一端を
パイロツト室に臨ませ、他端を作用室に臨ませ、
しかも、プランジヤの周囲にスリツトを形成し、
当該プランジヤが作用室からパイロツト室に向か
つて移動したとき、上記スリツトを介して作用室
とパイロツト室とを連通させるとともに、上記作
用室と弁本体に形成のタンク通路とをオリフイス
を介して連通させた方向制御弁。 In a directional control valve in which a spool is installed in the valve body and the spool is switched by the action of pilot pressure, both ends of the spool face an action chamber that communicates with a tank passage formed in the valve body. A pilot chamber is provided adjacent to the pilot chamber, one end of the slidable plunger faces the pilot chamber, the other end faces the action chamber,
Moreover, a slit is formed around the plunger,
When the plunger moves from the action chamber toward the pilot chamber, the action chamber and the pilot chamber are communicated through the slit, and the action chamber and a tank passage formed in the valve body are communicated through an orifice. directional control valve.
