造。[Scope of Claim for Utility Model Registration] 1. A cylindrical spool that can slide on the inner surface protrusion of the cylindrical ring is provided, and a check spring chamber and a pressure compensating spring are separated by a partition wall inside the cylindrical spool. The chamber is partitioned, and the cylindrical ring is provided with an inlet that communicates with the flow rate setting throttle valve and an outlet that communicates with the outlet during control, and the cylindrical spool is A pressure compensation structure for a flow rate regulating valve, characterized in that an inlet/outlet hole corresponding to the inlet and a throttle hole corresponding to the outlet are open. 2. The pressure compensation structure for a flow rate regulating valve according to claim 1, wherein the cylindrical spool has a small hole that opens at the fully closed position of the throttle hole or at a position that overlaps the throttle hole.
