ABSTRACT:
An improved oil seal is provided for sealing passage of rotatable shaft through an end wall of a bearing housing in a turbomachine or the like, wherein the shaft is rotatably supported within the bearing housing by oil-lubricated bearings. The improved oil seal comprises a slinger rotor mounted on the shaft for rotation therewith. The slinger rotor has an inner surface with an annular cavity and axially extending lands separated from each other by axially extending slots. The cavity and slots define a low velocity zone in which oil is centrifuged out. The slots and cavity so the centrifuged oil flows away from the end wall of the bearing housing. A labyrinth, air seal is disposed between the shaft and end wall.
