Slinger arrangement for use with bearing of supercharger
A slinger arrangement whereby the lubricating oil supplied to a bearing of a turbine shaft may be prevented from being sucked through one or more seal rings into a blower when the pressure in the blower becomes negative.
According to one embodiment of the present invention, the slinger consists of a large- and small-diameter sections, and a first seal ring is fitted into a circumferential groove formed in the large diameter section and contacts the lower end of first and second air vent chamber casings which is remote from a fan wheel, the first and second casings being axially spaced apart from each other and cooperating to define an air vent chamber, while a second seal ring is fitted into a circumferential groove formed in the small-diameter section and contacts the lower end of the other air vent chamber casing which is closer to the fan wheel. A circumferential oil throwing groove may be formed in the large-diameter section between the first and second seal rings.
