新案登録請求の範囲第１項記載の速度調節弁。[Scope of Claim for Utility Model Registration] 1. A housing that has supply and discharge ports connected to a working fluid flow path formed at both ends, and houses a flow hole structure in which a flow hole that communicates the both supply and discharge ports is formed through the housing. By forming a horizontal hole passing through the communication hole at right angles in the communication hole structure, and fitting into the horizontal hole a spool that changes the amount of blocking of the communication hole by moving in the axial direction. A spool valve is configured, and a threaded rod connected to the spool is screwed into a threaded hole formed on the side surface of the housing so as to be rotatably protruded to the outside, without passing through the communication hole in the housing. In the communication space that communicates both the supply and discharge ports, an elastic piece for checking is installed, which allows only flow from one of the supply and discharge ports to the other supply and discharge port with elastic deformation due to fluid pressure. Features a speed regulating valve. 2. The speed regulating valve according to claim 1, wherein the spool is provided with an inclined surface whose radial dimension gradually changes on the outer periphery of the spool.
