摘要

The present invention relates to compression based engine boosting systems, and, more particularly, to a supercharger configuration for higher pressure applications.

主权项

1. A boost system for an engine comprising:
a supercharger housing including a rotor cavity and gear case; an input drive shaft that is configured to be driven by the engine, the input drive shaft being at least partially housed within the gear case of the housing; a first rotor drive shaft at least partially housed within the rotor cavity of the housing; a second rotor drive shaft at least partially housed within the rotor cavity of the housing; a gear assembly that transfers torque between the input drive shaft and the first and second rotor drive shafts at least partially housed within the gear case of the housing; a first ring seal located on the first rotor shaft in the rotor cavity adjacent the gear case; a second ring seal located on the second rotor shaft in the rotor cavity adjacent the gear case; a first annular oil seal located on the first rotor shaft between the first ring seal and the gear case; a second annular oil seal located on the second rotor shaft between the second ring seal and the gear case; a first air vent pathway located between the first annular oil seal and the first ring; and a second air vent pathway located between the second annular oil seal and the second ring.
