Abstract
A regulator may include an inlet from which a high-pressure fluid is introduced, a valve seat provided at the inlet, and a pressure regulating valve body. The fluid may pass an opening between the valve seat and the valve body formed with a communication passage to a pressure regulating chamber. A load generated by pressure of pressure-regulated fluid acting on a piston unit joined to the valve body may be balanced with a load by a pressure regulating spring in an atmosphere chamber provided coaxially in parallel with the pressure regulating chamber on an opposite side of the piston unit. Fluid pressure of the pressure regulating chamber may be controlled by changing an opening area between a valve-seated seat and the valve body. The valve seat holding the valve-seated seat may be installed on an elastic member via a buffer having a sliding performance.
