Claims (1)
ールが移動するとともに、そのスプールの移動量
に応じて当該アクチユエータの戻り側通路の開度
を制御するカウンターバランス弁において、上記
パイロツト室内に臨ませたスプール端に小径部を
形成し、この小径部にキヤツプ状にしたガイド部
材を摺動自在にかぶせるとともに、このガイド部
材と小径部とのかん合すき間を十分ん小さくする
一方、このかん合すき間を通過した油をタンクに
導く構成にしたカウンターバランス弁。 The spool moves under the action of the pilot pressure in the pilot chamber, and in the counterbalance valve that controls the opening of the return side passage of the actuator according to the amount of movement of the spool, a counterbalance valve is installed at the end of the spool facing into the pilot chamber. A small diameter portion is formed, and a cap-shaped guide member is slidably covered over this small diameter portion, and the engagement gap between this guide member and the small diameter portion is made sufficiently small, and the oil passing through this engagement gap is A counterbalance valve configured to lead the water to the tank.
