Abstract
Official abstract text for this publication.
A variable geometry turbine comprising: a housing; a turbine wheel supported in the housing for rotation; an annular inlet passage defined between respective inlet surfaces defined by an annular nozzle ring and a facing annular shroud; the nozzle ring can vary the size of the inlet passage; a circumferential array of inlet vanes; the shroud covering the opening of a shroud cavity defined by the housing inlet passage and inboard of the shroud, and defining a circumferential array of slots, the slots and shroud cavity being configured to receive said vanes accommodating movement of the nozzle ring; wherein the annular shroud comprises an outer flange, the outer flange defining a circumferential groove for receiving a retaining ring for securing the shroud in the opening of the shroud cavity and defined on an inboard side by a flange wall; wherein an annular flange rim extends axially inboard from said flange wall.
First claim
Opening claim text (preview).
The invention claimed is: 1. A variable geometry turbine comprising: a housing; a turbine wheel supported in the housing for rotation about a turbine axis; an annular inlet passage upstream of said turbine wheel defined between respective inlet surfaces defined by an annular nozzle ring and a facing annular shroud; the annular nozzle ring being axial movable to vary the size of the inlet passage; a circumferential array of inlet vanes supported by the annular nozzle ring a…
