An integrated bearing system with journal and thrust bearings is incorporated in a single unit centrally pinned to the bearing housing and having integral thrust surface and journal surface lubrication grooves in combination with turbine and compressor wheel thrust surfaces. The bearing employs a first aperture substantially equidistant from the ends to engage the locating pin to prevent rotation of the bearing within the bearing case bore, while allowing the bearing to be free to symmetrically wobble within the bearing case bore.

An engine exhaust gas system includes a conduit for transferring exhaust gas, and a butterfly valve within the conduit for controlling communication of exhaust gas through the conduit. The butterfly valve is mounted on a shaft for pivoting relative to the conduit. The shaft is supported on a bushing in a transverse bore. Leakage through the clearance between the bushing and the shaft acts upon the transverse face of a washer which is freely slidable on the shaft, urging the latter into engagement with a retaining ring carried on the housing to effect sealing of the clearance. As the pressure of exhaust gases increases, the washer is urged more forcefully against the retaining ring, thereby improving the effectiveness of the seal.
