Patent ID: 7717101

Claim:
A centrifugal oil mist separator device integrated into an axially hollow shaft ( 1 , 101 ), wherein the shaft ( 1 , 101 ) is provided with radial oil mist inlet openings ( 9 , 106 ) for oil mist to be fed into the axially hollow space of the shaft ( 1 , 101 ) at the first end, and on the second end for draining with a radial oil discharge channel ( 13 , 112 ) for oil separated as a liquid phase on the one hand and an axial gas discharge channel ( 5 , 113 ) for the oil mist stream remaining after the liquid component has been separated on the other hand, a centrifugal oil mist pre-separator is connected upstream from the radial oil mist inlet openings ( 9 , 106 ) as a pre-separator ( 8 ) connected fixedly to the shaft ( 1 , 101 ), and a spiral flow generating device ( 6 , 108 ) is provided as the final separator within the axially hollow space of the shaft ( 1 , 101 ).
