Abstract:
1. A device for separating oil particles from blow-by gases of a crankcase ventilation of internal combustion engines, consisting of a source of crankcase ventilation, at least one plate-type base support having several flow tubes, tops of the flow tubes are completely closed off by a cover plate, a tangentially arranged gas/liquid inlet at an upper side of each of the tubes, and a gas/liquid outlet at a bottom opening of each of the flow tubes, wherein the liquid will deposit on the inner wall of the flow tubes, and the gas is centrally surrounded by said liquid as they are discharged from said gas/liquid outlet, wherein a combined rotational and axial flow with a vortex component is generated in the flow tubes, wherein the rotational flow in the individual tubes repeatedly rotates by 360° .
