Patent Images
1. A method for attaching a turbocharger end housing (2, 5) to a turbocharger bearing housing (3), the method comprising:
- (a) identifying complementary contact surfaces between the end housing and the bearing housing,(b) applying a flow/able sealing material to at least one of said complementary surfaces,(c) drying or curing the sealing material to form a dried or cured solidified coating, and(d) assembling the turbocharger such that the coating forms a gas barrier.

Abstract
To prevent escape of exhaust gas and soot from a turbocharger, a heat resistant sealing material is applied to a contact surface between a turbocharger bearing housing and center housing, and cured or dried to form a thin solidified coating. The end housing is then assembled to the bearing housing, whereby the coating provides a gas and soot seal between the bearing housing and end housing. The inventive seal could however also be used to seal the connection between two turbine stages, or any parts attached to a turbocharger end housing and subject to pressure.
