Document Type and Number:
Japanese Patent JP7197132
Kind Code:
B2
Abstract:
In a regulator in which a high-pressure fluid introduced from a fuel inlet passes an opening between a valve seat provided at the fuel inlet and a pressure regulating valve body formed with a communication passage to a pressure regulating chamber provided to face a valve-seated seat arranged on the pressure regulating chamber side of the valve seat, a load generated by pressure of pressure-regulated fluid acting on a piston unit joined to the pressure regulating valve body is 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 pressure regulating chamber of the piston unit, and fluid pressure of the pressure regulating chamber is controlled by changing an opening area between the valve-seated seat and the pressure regulating valve body, the valve seat holding the valve-seated seat is installed on an elastic member via a buffer having excellent sliding performance for automatic alignment.
