還流装置。 In a blow-by gas recirculation system for an internal combustion engine, the blow-by gas recirculation system for an internal combustion engine is equipped with a flow control valve in a passage communicating between a space inside a cylinder head cover and the inside of an intake passage that generates negative pressure. An auxiliary passage that receives negative pressure is provided, and an auxiliary flow control valve is installed in the auxiliary passage, and the auxiliary flow control valve opens when the pressure difference between the upstream side of the flow control valve and the upstream side of the auxiliary flow control valve exceeds a predetermined value. A blow-by gas recirculation device for an internal combustion engine, characterized in that a pressure valve for valving is installed in an auxiliary passage upstream of the auxiliary flow rate control valve.
