特徴とするエアバイパスバルブ。 A valve connected to an air bypass passage that communicates the upstream side of the turbocharger with the downstream side of the turbocharger and the upstream side of the throttle valve in an engine equipped with a turbocharger, a diaphragm that opens and closes the valve, and a diaphragm that opens and closes the valve. and a first chamber formed on the side of the throttle valve and into which boost pressure downstream of the throttle valve is introduced, and the air bypass valve operates the diaphragm by the boost pressure to open the valve,
A second chamber is formed on the other side of the diaphragm, and a passage is provided in the second chamber, which is separated from the air bypass passage and introduces supercharging pressure downstream of the turbocharger and upstream of the throttle valve. An air bypass valve featuring:
