TURBINE FOR AN EXHAUST GAS TURBOCHARGER
First Claim
1. A turbine for an exhaust gas turbocharger of a combustion engine, comprising a turbine casing (14) including an installation space (18), a turbine wheel (20) arranged in the installation space (18) so as to be rotatable about an axis of rotation (22) at least one inlet flow duct (38) via which exhaust gas of the combustion engine may be supplied to the turbine wheel (20), a guide vane structure (72) arranged in the inlet flow duct (38) and including vanes which are pivotably supported relative to the turbine casing (14), the vane structure (72) being delimited in the axial direction of the installation space (18) at least partially by at least one wall portion (70) of the turbine (12) which is at least partially overlapping the guide vane structure (72), the wall portion (70) comprising a first wall area (80) which is arranged adjacent the guide vane (72), and which is set back relative to a second wall area (82) of the wall portion (70) adjoining the first wall area (80).

Abstract
In a turbine for exhaust gas turbocharger of a combustion engine with a turbine casing forming an installation space in which a turbine wheel is arranged so as to be rotatable about an axis of rotation and into which exhaust gas of the combustion engine may be supplied via at least one flow duct in which a guide vane structure is arranged, the guide vane structure includes vanes, which are pivotably supported relative to the turbine casing and form an axial inlet nozzle structure adjacent a wall portion of the turbine which extends along the guide vane structure, the wall portion comprising at least a first guide wall area which overlaps the guide vane structure, and which is set back relative to a second guide wall area in which the vanes are pivotably supported and which adjoins the first wall area.
