Abstract
A turbocharger includes a shaft extending between first and second shaft ends. A turbine wheel is coupled to the first shaft end, and a bearing housing defines a bearing housing interior and is disposed about the shaft. A turbine housing defines a turbine housing interior and is disposed about the turbine wheel. A sealing assembly includes a case disposed about the shaft and extending between a first case end proximate to the turbine wheel and a second case end distal from the turbine wheel. The sealing assembly also includes a ring disposed between the shaft and the case such that the ring is unobstructed by the case radially between the shaft and the ring. The sealing assembly further includes a deformable component coupled to the second case end and to the ring, and is moveable with the ring to seal the bearing housing interior and the turbine housing interior.
