Title:
SUPERCHARGER ASSEMBLY WITH ROTOR END FACE SEAL AND METHOD OF MANUFACTURING A SUPERCHARGER ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2014/004141
Kind Code:
A3
Abstract:
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.
