るばねを係装して成る圧力補償付流量制御弁。 It has a valve body formed by integrally fixing the mutually facing side surfaces of two main body members by friction welding, and a connecting screw for piping threading is opened on both opposing sides through the fixed part of the valve body. An inflow hole and an outflow hole are provided for the fluid, and one main body member of the valve body is provided with a projecting protrusion in the center of the side surface to which it is fixed, and the valve body is connected to the outflow hole and extends into the protrusion. A side surface that is provided with a bottomed sliding hole and a communication hole that communicates with an annular groove formed by recessing the inner periphery of the sliding hole and opens on the outer surface of the convex portion, and that is fixed to the other main body member of the valve body. A concave part that accommodates the convex part of one main body member with a gap on the side and can form a fluid flow path is connected to the inflow hole to form a depression, and the sliding hole of one main body member A cylindrical pressure compensating spool with a restriction hole for controlling fluid constriction in a through-hole is slidably inserted into the through-hole, and a hole opening on the cylindrical outer surface of the pressure compensating spool and a hole on the inner circumference of the sliding hole are inserted into the cylindrical pressure compensating spool. The annular groove forms a variable throttle part whose opening area changes as the pressure compensation spool slides in the axial direction. A pressure-compensated flow control valve equipped with a spring that applies spring force in the increasing direction.
