Patent ID: 8893688

Claim:
A device for venting a crank space in an internal combustion engine, comprising: a suction device for suction removal of blow-by gases from the crank space, wherein a vacuum is created by the suction device in the crank space; a venting line leading from the crank space to the suction device, one of a throttle device and a pressure-regulating element arranged in the path of the venting line to limit the vacuum created by the suction device in the crank space, and an oil mist separator that is an impacter integrated into one of the throttle device and the pressure-regulating element that is selected; wherein the pressure-regulating element is selected and has one of a spring-loaded throttle valve and an elastic, rotationally symmetrical diaphragm; and wherein the elastic diaphragm is selected and has a conical mandrel which passes through a through-opening in the selected pressure-regulating element when the pressure-regulating element is at least partially closed such that, together with an opening edge of the through-opening, the elastic diaphragm forms a nozzle and is covered at least partially with a nonwoven material for separation of oil mist.
