を特徴とする負圧制御弁。[Claims for Utility Model Registration] A valve body 1, a shaft 2 with the valve body 1 attached to one end, a diaphragm 3 attached to the other end of the shaft 2, and a negative pressure chamber 4a formed by the diaphragm 3. Air chamber 4b
The negative pressure chamber 4a has a negative pressure introduction path 4C, and the air chamber 4b has an air introduction path 4d, an air outlet path 4e for controlling the power valve, and an air outlet path 4f for controlling the EGR valve. and a nozzle 4g connected to these air outlet paths 4e and 4f. 4h denotes a housing 4 projecting from the upper and lower walls of the valve body 1, and a spring attached to the negative pressure chamber 4a of the housing 4 to bias the valve body 1 toward the nozzle 4h. 5, and when the negative pressure in the negative pressure chamber 4a is lower than the set pressure of the valve body, the valve body 1 presses against the nozzle 4h, closes the air outlet passage 4f, operates the EGR valve, and closes the air outlet passage 4e. When the negative pressure in the negative pressure chamber 4a is higher than the set pressure, the valve body 1 presses against the nozzle 4g and air is released in the opposite direction from before.
In the negative pressure control valve which closes the outlet passage 4e and opens the air outlet passage 4f, the center of the nozzle 4h is eccentric to the center of the valve body 1 and is set at a position concentric with the center of the nozzle 4g. Pressure control valve.
