Claims

[Scope of utility model registration request]

In an internal combustion engine in which an intake pipe is connected via a turbocharger and a throttle valve, an upstream chamber of the throttle valve;
A bypass passage that communicates between the downstream chambers and can supply bypass air, a first chamber that is separated by a diaphragm and that can introduce negative intake pressure during idling, and a first chamber that is interposed in the bypass passage. a control valve having a second chamber, which closes the bypass passage by a pressing force constantly acting on the diaphragm, and opens the bypass passage by introducing negative pressure into the first chamber; An idle-up device for a supercharged internal combustion engine, comprising a pressure introduction passage communicating between a first chamber.
