<P>PROBLEM TO BE SOLVED: To provide a blowby gas recirculation device adaptive to blowby gas having large pulsation. <P>SOLUTION: A plurality of reed valves having different opening/closing characteristics are disposed in series along a flowing direction of blowby gas on an upstream side of a labyrinth structure 601 for separating lubricating oil contained in flowing blowby gas from blowby gas. A valve element 603 of the reed valve acts as the labyrinth structure 601 and removes the lubricating oil from blowby gas. Further, the reed valves of a plurality of stages repress pulsation of blowby gas flowing in the labyrinth structure 601. <P>COPYRIGHT: (C)2013,JPO&INPIT |
