Abstract: With known devices for separating oil in the crank housing ventilator, oil is collected on a refined gas side of a filter, which in operation of an internal combustion engine, often cannot drain off. In this manner, the liquid level increases, so that the filter is increasingly clogged by the oil. Finally, the oil is carried away from a gas stream. In this manner, the oil use of the internal combustion engine greatly increases. With the device of the present invention, the oil collected on the refined gas side is collected in a liquid storage unit (10), whereby the liquid storage unit (10) is protected from the stream, so that the gas stream can not carry away oil any longer. The device includes a support body (9), which is impermeable to the stream by means of a cut-off wall (23), in order to prevent a carrying-off of the oil.
