Claims

[Scope of utility model registration request]

A filter element with a porous structure for gas-liquid separation is provided in the middle of the blow-by gas passage, and the filter element is rotatably supported by an eccentric shaft, and when the pressure in the blow-by gas passage is not above a predetermined value, the blow-by gas passage is closed. A blow-by gas reducing device for an internal combustion engine, characterized in that the device is located at a position extending across the blow-by gas passage and is configured to be pushed open by the pressure when the pressure in the blow-by gas passage is equal to or higher than a predetermined value.
