Radial-flow exhaust gas turbocharger turbine with adjustable guide vanes

摘要

In a radial-flow exhaust turbocharger turbine with a row of individually adjustable guide vanes (18), said guide vanes can be turned by means of an adjusting shaft (19) supported in a casing (14). Each adjusting shaft (19) is actuated by means of a pivoting lever (21). In each case two adjacent pivoting levers (21) are coupled by means of a connecting element (24). The connecting elements have a pivot (25) at their point of attachment to the pivoting lever. The distance (A) between the pivots (25) of a connecting element corresponds to the center distance (B) between two adjacent adjusting shafts (19). As a result, all the pivoting levers perform the same angular movement.
