Claims

[Scope of utility model registration request]

A positive displacement supercharger that is constantly driven by the internal combustion engine in the intake system from the air cleaner to the internal combustion engine;
The leak passage includes a leak passage for discharging a part of the supercharged air from the supercharger and a throttle valve for regulating intake air to the internal combustion engine, while the leak passage is configured to open and close the leak. In a supercharged internal combustion engine equipped with a leak valve, a piston fitted in one of the two cylinders connected through a fluid passage is attached to a lever on the valve shaft of the throttle valve in the other cylinder. A piston that fits into a cylinder is connected to a lever on the valve shaft of the leak valve so that when the throttle valve opens, the piston in the other cylinder moves and the leak valve closes, and the leak valve is opened. A restricting orifice and a check valve that opens only in the direction from the other cylinder to one cylinder are provided in parallel in the fluid passage connecting the two cylinders. An internal combustion engine with a supercharger.
