Abstract
An oil separator for the gases of the crankcase ventilating system of an internal-combustion engine has a filter element through which the breathing gases flow and from which the separated oil is returned via an oil return into the oil tank 4. The blow-by gases, from which the oil was removed, are supplied to the air intake system of the internal-combustion engine. A vacuum generator is provided which generates a specified constant vacuum for the sucking-off of the blow-by gases. In addition, an air oil removal element that separates the oil has microfibers which are made of fiber glass material.
