構成したことを特徴とする圧力制御弁。(1) A diaphragm for use in automobiles having a booster in the engine intake system, which separates a first pressure chamber to which positive or negative pressure generated in the intake system is applied and an atmospheric chamber into which atmospheric air is introduced. , when the positive pressure is applied above a specified value,
The valve body that contacts the valve seat, which is the communication hole between the atmospheric chamber and the second pressure chamber located adjacent to it via the partition, opens according to the displacement of the diaphragm, and operates using negative pressure as a control signal. In a pressure control valve that controls the actuator by introducing atmospheric air into a control pressure chamber or a control pressure passage of an actuator, a hemispherical valve body is brought into contact with the valve seat by a spring, and a convex portion is formed on the valve body or diaphragm side. The protrusion and the opposing diaphragm or valve body are arranged at a certain distance apart without being connected, and when the diaphragm is displaced, the valve body resists the spring force through the protrusion. A pressure control valve characterized in that it is configured to open by pressing the button.
