VARIABLE TURBINE OR COMPRESSOR GEOMETRY FOR AN EXHAUST GAS TURBOCHARGER

摘要

A variable turbine and/or compressor geometry for an exhaust gas turbocharger may include an adjusting ring for simultaneously adjusting a plurality of guide vanes. The adjusting ring may be operatively connected to an articulated lever via a first contact surface and to an associated adjusting lever of the plurality of guide vanes via a second contact surface. The adjusting ring may include, at least in a region of the first contact surface, an additional component which is pressed into the adjusting ring and which increases the first contact surface operatively connected with the articulated lever.
