Abstract
The disclosure concerns a venting device for the housing of a rotary machine. The housing has a venting duct leading from the interior of the housing outwardly through a liquid-mist or oil-mist separator. A peeling device is arranged closely adjacent to the peripheral surface of a rotating member of the rotary machine. The peeling device intercepts the boundary layer of mist laden air that is rotating with the peripheral surface and directs the air boundary layer into the venting duct which in turn extends to a liquid or oil-mist separator or filter. The peeling device thus transforms the kinetic energy of the oil laden atmosphere at the peripheral surface of the rotating member into pressure which will drive the oil-mist laden atmosphere through a filter. The peeling device is directed so that it has an entrance opening facing in a direction counter to the direction of rotation of the rotating member so that it will peel off the boundary layer of liquid-mist or oil-mist laden air as the rotating member rotates.
