ABSTRACT:
An exhaust gas turbine for an exhaust gas turbocharger has a nozzle ring having an inner ring and an outer ring supporting a plurality of guide vanes. The nozzle ring is diagonally supported between a covering ring and the inlet casing, with the outer ring bearing against the covering ring and the inner ring bearing against the inlet casing. The outer ring provides an axial expansion gap with gas inlet casing and a radial expansion gap with the gas outlet casing. The nozzle ring is free to expand into the axial and radial gaps as a result of thermal expansion, without causing stress to the adjacent components.
