Claim Text:
1. A supercharger system comprising: a supercharger main housing enclosing one or more active components for moving air from an upstream side to a downstream side of the supercharger main housing; a supercharger inlet housing mounted at the upstream side of the supercharger main housing; a re-circulation line that provides fluid communication between the downstream side of the supercharger main housing and the supercharger inlet housing; and the supercharger system including multiple operating positions including an open operating position and a closed operating position; wherein in the open operating position recirculation air is allowed to flow through the re-circulation line from the downstream side of the supercharger main housing to the supercharger inlet housing, and in the closed operating position recirculation air is prevented from flowing through the re-circulation line; and a flow diverter being positioned within the supercharger inlet housing, the flow diverter remaining stationary throughout action of the multiple operating positions of the supercharger system such that the flow diverter has a constant configuration, location, and direction between conditions of the open and closed operating positions, the flow diverter having first and second portions within the supercharger inlet housing, the first portion defining a first re-circulation flow direction and the second portion defining a second re-circulation flow direction, the second re-circulation flow direction being angled relative to the first recirculation flow direction, the second portion being located at an outlet end of the re-circulation line, the second re-circulation flow direction maintaining a fixed orientation relative to a main flow direction through the supercharger inlet housing at the location of the outlet end of the re-circulation line as the supercharger system is moved between the open and closed operating positions, wherein the flow diverter includes a flow turning surface that provides a curved transition between the first and second portions such that recirculation air immediately exiting the second portion of the flow diverter has the same flow orientation as naturally aspirated air entering the supercharger.
