する開閉弁。An operating shaft is attached to a valve housing provided with a fluid supply path so as to be movable in an axial direction, and a valve body provided on the operating shaft faces the supply path, and a valve seat provided on the supply path. The valve body is biased from the upstream side by a spring to resiliently seat the valve body, thereby blocking the supply path, and the valve body is moved away from the valve seat portion by advancing and retracting the operating shaft, thereby causing the valve body to be seated elastically. An on-off valve that communicates a supply path, characterized in that a piston is provided on the outer periphery of the operating shaft, and upstream fluid pressure is applied to the piston in a direction opposite to that of the valve body. .
