ゼルエンジンのブローバイガス還流装置。 A blowby gas recirculation pipe installed in the intake pipe to recirculate the blowby gas in the crankcase into the intake pipe of the engine and having a blowby gas outlet on the pipe wall on the downstream side with respect to the intake flow; a dynamic pressure chamber provided with a dynamic pressure inlet that is formed in a downstream portion adjacent to the blowby gas outlet and substantially directly facing the intake flow; and a partition wall that partitions the blowby gas passage and the dynamic pressure chamber in the blowby gas recirculation pipe. It comprises a piston member that is slidably mounted and controls the opening area of the blow-by gas outlet by the displacement of the pressure-receiving head in the blow-by gas passage, and the piston member receives the pressure of the pressure-receiving head in the blow-by gas passage. A blow-by gas recirculation device for a diesel engine, characterized in that the area is larger than the pressure receiving area of a pressure receiving head in a dynamic pressure chamber of the piston member.
