Abstract
An oil separation device for separating oil from a gas stream for ventilating a crankcase of a combustion engine may include an inflow side and an outflow side. The inflow side can be fluidically connected to the crankcase of the combustion engine and may receive the gas stream laden with oil. The outflow side can be fluidically connected to an intake tract of the combustion engine and may receive the gas stream substantially purged of oil. The device may include a first control member for varying a first flow cross section of the gas stream and controlled by a gas pressure in the crankcase. The device may have a second control member for varying a second flow cross section of the gas stream positioned downstream of the first flow cross section, wherein the second control member is controlled by a vacuum in the intake tract of the combustion engine.
