Abstract
A supercharger for an internal combustion engine having an internal reservoir adapted to receive a supply of lubricating oil. An oil slinger is mounted on the impeller shaft for rotation therewith that extends into the reservoir for collecting and slinging lubricating oil onto the supercharger bearings, shafts and the drive and impeller gears. A baffle assembly is carried by the interior of the supercharger housing for controlling the volume and flow of lubricating oil onto said gears and bearings and directing oil flow therefrom back into said reservoir to prevent excessive lubrication buildup on the gears and the deleterious effects that result therefrom.
