Abstract
A variable geometry turbine comprises a turbine wheel supported in a housing for rotation about a turbine axis. An exhaust gas inlet passageway is defined between a shroud and a wall of a nozzle ring. The shroud is moveable in the axial direction to vary the size of the inlet passageway. The nozzle ring has an array of vanes that extends across the inlet passageway. An array of openings is provided in the shroud for receipt of the array of vanes. The shroud is part of a substantially annular axially moveable sleeve that is slidably disposed on an annular supporting wall. At least one biasing member is disposed between the moveable sleeve and the support and is designed to apply a circumferentially distributed force in the radial direction so as to maintain concentric alignment of the supporting wall and the sleeve.
