Abstract
Gases produced by a combustion engine, e.g. crankcase gases, are conducted through a separation chamber formed and surrounded by a centrifugal rotor, by means of which the gases are caused to rotate, so that particles suspended in the gases are separated by means of centrifugal force. The centrifugal rotor is caused to rotate by means of a pressure fluid that is generated by means of the combustion engine.
