OIL MIST SEPARATOR

摘要

The invention relates to an oil mist separator (1) for a positive crankcase ventilation system, comprising a first separator unit (2) with at least one filter body (4) which is arranged in such a way in a blow-by gas path (5) that blow-by gas can pass through said body, and comprising a second separator unit (3), which is located in a bypass path (6) that bypasses the first separator unit (2). Said second separator unit has a bypass valve (7) that opens the bypass path (6) when a differential pressure in the first separator unit (2) exceeds a predefined value. An improved service life can be achieved if the second separator unit (3) is designed as an impactor separator.
