Abstract (en)
[origin: WO2004105955A1] The invention relates to a device for separating oil from crankcase ventilation gases of an internal combustion engine, comprising at least two oil separation elements in the form of cyclones, said elements being traversed by the crankcase ventilation gases. Said cyclones are connected in parallel. The device is equipped with a control valve that divides the volumetric flow of the crankcase ventilation gases into at least two volumetric sub-flows, depending on the size of the volumetric flow, and conducts said sub-flows to at least two oil separation elements. A control piston releases or seals the access of the gas to the first cyclone or to an additional cyclone according to the dynamic pressure of the crankcase gas.
