OIL MIST SEPARATOR

摘要

The invention relates to an oil mist separator (1) for a positive crankcase ventilation system. Said separator comprises a first separator unit (2) with at least one filter body (10) which is arranged in such a way in a blow-by gas path (11) that blow-by gas can pass through said body. The separator is equipped with a second separator unit (3), which is located in a bypass path (18) that bypasses the first separator unit (2). The bypass path (18) can be opened by a bypass valve (4) when a differential pressure in the first separator unit (2) exceeds a predefined value. A particularly cost-effective and efficient design can be obtained if the second separator unit (2) is designed as an impactor separator.
