Turbine for exhaust gas turbocharger of internal combustion engine, has gap having first length portion extending in axial direction and which is smaller than the second length portion of gap, adjoining and extending in axial direction

摘要

The turbine (10) has a guide element (30) for deriving exhaust gas, and an adjusting device (32) having a sliding control element (34) displaceable in axial direction of turbine wheel (16) relative to guide element between closed position (Xmin) and release position (Xmax). The control element covers guide element in release position and releases guide element in closed position, while forming a gap (46) between the elements. The first length portion (50) of gap, extending in axial direction is smaller than second length portion (52) of gap, adjoining and extending in axial direction.
