Integrated supercharger and charge-air cooler system

A supercharger system includes 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. The system includes a supercharger inlet housing mounted at the upstream side of the supercharger main housing and a re-circulation line. The re-circulation line provides fluid communication between the downstream side of the supercharger main housing and the supercharger inlet housing. The line includes a flow diverter having first and second portions within the supercharger inlet housing. The first portion defines a first re-circulation flow direction and the second portion defines a second re-circulation flow direction. The second direction may be 45-135 degrees relative to the first recirculation direction.

Supercharger air flow diverter

A supercharger transmission includes a first chamber having timing gears operatively disposed therein. A second chamber has transmission gears operatively disposed therein. An oil fill level is defined in the second chamber. A bearing retention wall is disposed between the first chamber and the second chamber. The bearing retention wall includes a return port to allow fluid communication between the first chamber and the second chamber. The return port is an aperture defined in the bearing retention wall below the oil fill level. The bearing retention wall also includes a crosstalk port to allow fluid communication between the first chamber and the second chamber. The crosstalk port is an aperture defined in the bearing retention wall above the oil fill level.
