Abstract
A variable geometry turbine comprises a turbine wheel () supported in a housing for rotation about a turbine axis with an annular inlet passageway () defined between a radial face of a nozzle ring () and a facing wall of the housing (). The nozzle ring is movable along the turbine axis to vary the width of the inlet passageway and has a circumferential array of vanes () that are received in corresponding slots () in the facing wall. A wastegate valve () is provided in a chamber behind the facing wall and gas bypasses the turbine through the chamber to the wastegate port () at high flow rates.
