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.

Variable turbine or compressor geometry for an exhaust gas turbocharger

An adjustment ring of a variable turbine geometry of an exhaust gas turbocharger is disclosed. The adjustment ring may include at least a first ring segment and a second ring segment.

Adjustment ring of a variable turbine geometry

An exhaust gas turbocharger may include a turbine housing and a turbine arranged in the turbine housing. The turbine housing may include at least two exhaust gas channels and a partition separating the at least two exhaust gas channels from one another. A wastegate valve may be arranged such that the at least two exhaust gas channels are connectable to a bypass duct bypassing the turbine. The wastegate valve may include a valve body and a valve seat interacting with the valve body. The wastegate valve may be configured such that at least one of a ram supercharging operation and a pulse supercharging operation is activated depending on a degree of opening of the wastegate valve.

Exhaust-gas turbocharger

An exhaust gas turbocharger may include a turbine housing and a turbine. The turbine housing may include at least two exhaust gas channels and a partition. A wastegate valve may be arranged such that the at least two exhaust gas channels are connectable to a bypass duct bypassing the turbine. The wastegate valve may include a hollow valve body and a valve seat interacting with the valve body. The wastegate valve may be configured such that at least one of ram supercharging and pulse supercharging is performed. A connecting opening may be arranged between the at least two exhaust-gas channels. The valve body may have a base region configured to facilitate a discharging of an exhaust-gas steam into the bypass duct and/or an overflowing of one exhaust gas channel through the connecting opening into the other exhaust-gas channel.
