Patent ID: 7789076

Claim:
A device for cleaning crankcase gases from a combustion engine comprising: an inlet conduit connectable to a crankcase of a combustion engine; a centrifugal separator, which is adapted to receive a flow of crankcase gases from the crankcase via the inlet conduit and which comprises a rotatable centrifuge rotor for centrifuging the crankcase gases; a drive device, which drives the centrifuge rotor; an outlet conduit, which is adapted to discharge cleaned crankcase gases from the centrifugal separator, the rotary speed of the drive device, and thus the rotary speed of the centrifuge rotor being controllable depending on the gas pressure in the crankcase; and wherein the device further comprises an export conduit, connected to the inlet conduit and adapted to enable discharge of a flow of crankcase gases from the crankcase by-passing the centrifugal separator depending on the gas pressure in the crankcase.
