特徴とするダイヤフラム式リリーフ弁。 An air intake port is connected to the downstream side of a supercharger disposed in the intake passage of the engine, and an air discharge port is connected to the upstream side of the supercharger, and one end of the shaft is fixed to the diaphragm.The other end of the shaft is connected to the air intake port and the discharge port. A valve body is provided so that the valve can be opened in the direction, and the diaphragm is moved by negative pressure in the intake passage to open the valve, and a part of the air supercharged by the supercharger is bypassed to the upstream side of the supercharger. In the diaphragm type relief valve, the valve body is slidable in the axial direction of the shaft,
In addition, when the diaphragm is displaced, it is engaged with the shaft so that the valve can be opened, and a spring is further provided that closes the valve body, and the diaphragm is displaced and opened by the negative pressure in the intake passage, and the supercharging is performed. The diaphragm type relief valve is characterized in that the valve body is opened by pressing the valve body against the spring force of the spring.
