Abstract: A centrifugal supercharger is provided. One embodiment of the supercharger comprises a two-piece housing wherein a parting area is substantially aligned with a rotational axis of a drive or impeller shaft. Another embodiment comprises a sleeve, or intermediate member disposed substantially between the housing and a bearing assembly(s) located within the supercharger housing. Another embodiment comprises a disengagement device located between the supercharger impeller and the engine. The disengagement device allows selective disengagement of the impeller from the engine. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained therein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

Abstract: A centrifugal blower is provided which incorporates a self-contained air cooling system. The blower includes a drive assembly connected to a drive motor and disposed within a housing having inlet and outlet apertures. A centrifugal compressor is connected to the drive assembly and disposed exteriorly to the housing adjacent to the outlet apertures. Rotation of a drive pulley, including a fan, by the drive motor causes air to enter the housing through the inlet apertures, flow over components of the drive assembly, and exit through the outlet apertures. A spindle assembly having a rigid bearing arrangement is also provided. One or more bearing elements are disposed at opposite ends of a spacer and between a shaft and housing of the spindle assembly. Such rigid pre-loaded bearing arrangement eliminates “unloading” concerns, and allows load sharing between bearing elements.
