SUPERCHARGER ASSEMBLY WITH ROTOR END FACE SEAL AND METHOD OF MANUFACTURING A SUPERCHARGER ASSEMBLY

A supercharger assembly has a rotor housing defining a chamber. A rotor is within the chamber and has an end with an end face. A seal has a seal face adjacent the end face. The seal face and the end face have complex topographies configured to be complementary to define a gap therebetween. The compl...

Zusammenfassung:	A supercharger assembly has a rotor housing defining a chamber. A rotor is within the chamber and has an end with an end face. A seal has a seal face adjacent the end face. The seal face and the end face have complex topographies configured to be complementary to define a gap therebetween. The complex topographies can be, but are not limited to, interfitting concentric annular channels. The gap functions as a tortuous flow path to inhibit fluid flow past the end face. A method of manufacturing a supercharger assembly is also provided. L'invention concerne un ensemble compresseur d'alimentation comprenant un carter de rotor définissant une chambre. Un rotor est situé à l'intérieur de la chambre et comprend une extrémité présentant une face d'extrémité. Un joint d'étanchéité comprend une face d'étanchéité adjacente à la face d'extrémité. La face d'étanchéité et la face d'extrémité présentent des topographies complexes conçues de manière à être complémentaires afin de définir un espace entre elles. Les topographies complexes peuvent être, de façon non limitative, des canaux annulaires concentriques encastrables. L'espace fonctionne comme un trajet d'écoulement tortueux permettant d'empêcher l'écoulement de fluide devant la face d'extrémité. L'invention concerne également un procédé de fabrication d'un ensemble compresseur d'alimentation.
