Abstract
PURPOSE: To prevent insufficient sealing in a case where the rectangular accuracy between the operating plunger, input valve seat and exhaust valve seat by connecting the valve member to the operating plunger in a swingable manner.
CONSTITUTION: When a knob 18 is pulled up, a seal projection 28 on the upper surface of a valve member 20 is seated on an input valve seat 14, to interrupt the communication between an input port 11 and a valve chest 10 and connect the valve chest 10 to the atmosphere through an exhaust port 13. Since a play gap is provided at the connected part of the valve member 20 and the operating plunger 17, the valve member 20 freely swings with respect to the operating plunger 17 so that entire periphery of the seal projection 28 on the upper surface of the valve member comes into contact with the input valve seat 14. Accordingly, the spring force of a pressure governing spring 30 acts uniformly on the entire periphery of the contact surface between the seal projection 28 and the input valve seat 14, and hence no insufficient sealing occurs.
