Claims

[Scope of utility model registration request]

A Uniis gate valve is provided in the bypass passage to the supercharger turbine of the exhaust system, and the actuator of the waste gate valve has a control chamber on one side of the diaphragm to which boost pressure is supplied from the boost pressure passage of the intake system, and the like. In an internal engine with a supercharger, which has a chamber that is open to the atmosphere on one side, and in which a spring is applied to the diaphragm, a pressure camosulator is provided in the middle of the boost pressure passage, and the pressure camosulator is connected to the The supercharging chamber into which supercharging pressure is introduced, the pressure regulating chamber supplying all of the adjusted pressure to the above-mentioned actuator control chamber, the atmospheric pressure chamber and the standard atmospheric pressure chamber are sequentially polymerized, and the supercharging pressure chamber and the pressure regulating chamber are A diaphragm having a small hole is provided to partition the chamber, and an on-off valve is provided between the pressure adjustment chamber and the atmospheric pressure chamber, which opens and closes by the displacement of the bellows and diaphragm of the standard atmospheric pressure chamber. Features: Boost pressure control device for internal combustion engines with a supercharger.
