いるチエツク弁。[Claim for Utility Model Registration] A valve that selectively seats on a valve seat cut out at the end of an inlet hole is given a biasing force from a spring from behind the valve seat, which is opposite to the valve seat. In a configuration in which an enclosed chamber communicates with an outlet hole, a damping material is provided between a shaft fixedly installed in the chamber and whose outer periphery is enclosed in the spring, and the valve in the axial direction. The damping material is provided such that one axial end of a thin cylindrical plate is integrally attached to the valve, and the other axial end of the cylindrical member is fitted to the shaft so as to be able to slide in the axial direction. The other end of the cylindrical axial direction is
A check valve having an axial groove provided at each of a plurality of divisions in the circumferential direction of the cylindrical shape, and having an elastic force directed inward in the radial direction at the other end in the axial direction.
