Claims

[Scope of utility model registration request]

In a pressure fluid circuit having two main circuits for supplying and discharging pressure fluid to and from an actuator, the two main circuits are fitted and fixed into connecting body inner holes, and one of the main circuits is connected to the first hole and the second main circuit. A fixed sleeve having a sleeve inner hole that communicates with the fixed sleeve through the hole, and a fluid pressure in the other main circuit that is slidably fitted into the sleeve inner hole of the fixed sleeve and applied to the fixed sleeve. a movable sleeve having an end in contact with a locking portion and an end portion that opens and closes the second hole, a valve seat portion is formed, and fluid pressure in the one main circuit acts through the first hole; A pressure control valve comprising a main valve having a small-diameter head abutting a valve seat portion and forming a pilot chamber on which fluid pressure in the other main circuit acts via a restriction and is controlled by a pilot valve.
