Title: Supercharger cooling means

Abstract

According to the present invention, a rotary blower or supercharger includes a recirculation loop for readmitting pressurized outlet gas back into the rotor chambers, and cooling means for cooling the pressurized outlet gas before it is readmitted into the rotor chambers, thereby providing a supercharger having a lower operating temperature and a higher operating pressure capability. In the preferred embodiment of the present invention, a supercharger includes a housing assembly defining first and second transversely overlapping cylindrical chambers. The housing defines an inlet port for the inflow of an inlet gas, and an outlet port for the outflow of the outlet gas. The supercharger further has first and second meshed, lobed rotors respectively disposed in the chambers for counter rotation about axes substantially coincident with the chamber axes. According to the present invention, the housing further includes a recirculation port and a recirculation flow path for recirculation of a portion of outlet gas flowing out of the outlet port back into cylindrical chamber. The recirculation flow path further including cooling means for cooling of at least a portion of the outlet gas, thereby providing a cooler operating supercharger.
