Abstract: A separation housing houses a rotor with multiple suspension chambers. Each chamber has a radially extending web portion between two rotating discs. An orifice is provided through the radially extending web portion. Another web portion urges gas radially out of the rotor. Passages through the rotating disks permit entry of gas and solid particle mixtures into the suspension chambers at high speed traveling toward each other in a suspension adjacent to the orifice. The web portion that urges gas out of the chamber pulls gas away from the suspension zone. Gas moving through the aperture and into a clean gas chamber pulls gas in the opposite direction. The result is gas in the suspension zone being fixed relative to the rotor or changing direction. Centrifugal force moves solid particles radially out of the chamber.

A rotating means is contained within the air chamber and may be driven to rotate about an axis that extends between the first end and the second end of the chamber. The rotating means applies a centrifugal force to any airborne particles entering the air chamber and throws them radially outwards from the central axis. These particles are then drawn out of the air chamber, via at least one second outlet formed adjacent to a radially outer edge of the rotating means, by a high-velocity outlet stream of the open-ventilation system.

Abstract: In a vehicle (1) adapted to be propelled by means of an internal com-bustion engine (2) crankcase gases coming from the combustion engine are cleaned by means of a centrifugal separator (11). The rotor of the centrifugal separator (11) is driven by means of pressurized air delivered by a compressor (4), e.g. a so called turbo compressor, which is driven by means of the combustion engine. During periods when the compressor (4) delivers pressurized air in an insufficient amount and/or at insufficient pressure the rotor of the centrifugal separator (11) is instead driven by means of pressurized air coming from a container (9) containing so called auxiliary pressurized air. The auxiliary pressurized air may have a substantially larger pressure than the pressurized air normally delivered by the compressor (4). The combustion engine (2) is used also for accomplishing the overpressure of the auxiliary pressurized air in the container (9).
