Abstract
Abstract The invention relates to an apparatus ( 10 ) for purifying gas while bleeding a crank housing, said apparatus ( 10 ) comprising a housing ( 12 ) inside which a separator chamber ( 14 ) is provided, a rotor arrangement with a rotor shaft ( 32 ) that is rotatably mounted in the housing and a centrifugal rotor ( 39 ) located in the separator chamber ( 14 ), and a fluid driving device ( 64 ) for driving the rotor shaft ( 32 ) by means of a driving fluid, the driving device ( 64 ) being disposed in a driving chamber ( 60 ) that is separated from the separator chamber ( 14 ) by means of a housing partition ( 16 ), and the rotor shaft ( 32 ) extending through a breakthrough in the housing partition ( 16 ). In the case of this device, it is provided that a labyrinth-type seal ( 70 ) is provided in the zone of the breakthrough in order to seal the driving chamber ( 60 ) from the separator chamber ( 14 ).
