Abstract

The present invention relates to a device for venting a crank space in an internal combustion engine (1) having a suction device (5) for sucking out blow-by gases from the crank space (3) and having a venting line (4) which leads from the crank space (3) to the suction device (5) and in the course of which a throttle device (6) or a pressure regulating element (7) is arranged in order to bound a partial pressure which is generated by the suction device (5) in the crank space (3). It is essential to the invention here that an oil mist separator (8) which is embodied as an impactor is integrated into the throttle device (6) or into the pressure regulating element (7).
