Patent ID: 8042529

Claim:
A device for eliminating oil particles from crankcase ventilation gas in an internal combustion engine, wherein the device is located in a flow duct of the crankcase ventilation gas that runs from a crankcase to an induction tract of the internal combustion engine and wherein the device comprises an oil separator in the form of an outlet for the crankcase ventilation gas with a deflection of the flow, causing the oil particles to be deposited on a baffle surface and thus to be eliminated from the crankcase ventilation gas flow, the device comprising: an infeed cross-section lying upstream of the baffle surface when viewed from a flow direction of the crankcase ventilation gas, being sub-divided by at least one structure into a multitude of infeed sub-sections which together function as a flow straightener; the infeed sub-sections comprising openings in the structure and each opening having a center point, with adjacent sub-section openings being separated from each other by a land, wherein a distance between center points of adjacent sub-section openings being at least twice as great as a width of the land between the adjacent sub-section openings; the baffle surface being a solid surface that is devoid of perforations; and the baffle surface being configured on at least one valve body, which lies downstream of the infeed sub-sections when viewed in the flow direction of the crankcase ventilation gas and which is pre-tensioned by a force, the valve body being displaceable in an opening direction in opposition to a pre-tension, as a result of a differential pressure between the crankcase and the induction tract.
