AXIS DRIVEN CENTRIFUGAL BREATHER Russian patent published in 2017 - IPC F02C7/06 

FIELD: mechanical engineering.

SUBSTANCE: bearing is placed inside the impeller, its inner holder is coaxially mounted on a formed in the housing of the impeller cylindrical finger. The outer bearing holder is fixed relative to the impeller. On either side of the bearing inside the impeller, isolated from its running parts of the chamber are formed, one of which on the inlet side of the impeller, communicated through formed in the blades of the radial channels to the channel outlet of separated oil, and the other chamber facing the rear side of the impeller, through axial and radial channels made inside the finger, it communicates with the oil inlet channel to the support bearing.
