Claims (1)
換える切換弁とを連結する１対の給排路にそれぞれ介装
された１対のスプールを具え、各スプールはその１端に
他方の給排路内の油圧または上記アクチュエータからこ
のスプールに至る第１の油路内の油圧を受けて、これら
油圧に応じてスプリングによる押圧力に抗して移動する
ことにより上記第１の油路とこのスプールから上記切換
弁に至る第２の油路との連通を断連制御するようにした
ことを特徴とする液圧制御弁。A pair of spools are respectively installed in a pair of supply and discharge passages that connect an actuator and a switching valve that switches supply and discharge of pressure oil to the actuator, and each spool has one end connected to the other supply and discharge passage. or from the first oil path and this spool by moving against the pressing force of the spring according to these oil pressures. A hydraulic control valve characterized in that communication with a second oil passage leading to the switching valve is controlled to be disconnected.
