A device for separation of oil from the hot gases ( 5 ) that are ventilated out from the crank house of a combustion engine. The separation is accomplished by contacting th gases with a cold wall ( 2 ) where the oil deposits and is then drained away. The wall ( 2 is kept cold by the cold gases ( 4 ) leaving the device which makes the cooling demand small. The leaving gases ( 4 ) are heated by this, so that a higher degree of separation f purification can be accomplished by the use of several similar steps in series.
