Abstract (en)

Device for ventilating a crankcase of an internal combustion engine comprises an arrangement for separating oil from the outgoing air which consists of a spinning wheel (108) with blades and an air outlet connector (118). The radial blades of the spinning wheel extend in the spinning wheel axial direction in the direction of the air outlet connector. The inlet opening of the air outlet connector is arranged at least approximately coaxially to the spinning wheel and the opening plane is at least approximately parallel to the spinning wheel plane. The inlet-side end region of the air outlet connector encloses a flow gap (120) with the blade edges on the air outlet connector side. Preferred Features: The gap has a width of 0.5-3, preferably about 1 mm. The spinning wheel is driven directly as a function of engine speed.
