ABSTRACT:
A radial-flow exhaust gas turbocharger turbine includes a row of individually adjustable guide vanes, each guide vane mounted on a rotatable shalt supported in the turbine casing. A chord of each guide vane is not greater that a largest diameter of the shaft on which the guide vane is mounted. When viewed in the axial direction, a profile of each vane lies completely within a radially outer contour of the associated shaft. This permits the design of a one-piece adjustable unit formed of a guide vane, a rotatable shaft, and a pivoting lever. The adjustable unit can be inserted into the casing or removed from the casing as a single unit to facilitate installation and maintenance.
