ABSTRACT:
The invention relates to a device (1), for the ventilation of the crankcase (20) of an internal combustion engine (2), with a breather tube (3), running from the crankcase (20) to an inlet manifold (22) on the internal combustion engine (2), in the course of which an oil-mist separator (30) is arranged. The novel device is characterized in that in the course of the breather line (3), a pump device is arranged, by means of which a reduced pressure may be generated in the crankcase (20) relative to ambient pressure.
