Title: Gas seal vanes of variable nozzle turbine

Abstract

In association with an engine described here, a turbocharger for supplying compressed air to the engine comprising: an exhaust gas driven turbine rotatably mounted to a shaft and having a compressor impeller thereon; a compressor housing having an inlet and an outlet and enclosing the compressor impeller; a center housing including bearing means for rotatably supporting the shaft; a turbine housing including an inlet and an outlet, the turbine housing forming a volute therein for directing exhaust gas from the engine through an annular passage to the turbine; a flange member mounted between the center housing and the turbine housing and having a recess therein defining a radially inner and outer surface, the surfaces being aligned axially, spaced radially apart and facing each other; a generally annularly shaped unison ring of slots therein and at least three equally spaced roller members rotatably mounted thereto, the rollers engageable with the inner surface during periods of relatively low exhaust gas temperature and engageable with the outer surface during periods of relatively high exhaust gas temperatures; a generally annular nozzle ring of vanes pivotably mounted thereto, each of the vanes having a vane arm which is engageable within a slot in the unisonmore » ring; a spring means for biasing vanes against the turbine housing; and means for preventing rotation of the nozzle ring.« less
