An exhaust gas turbocharger for an internal combustion engine is described, in the turbine housing of which there is arranged upstream of the turbine wheel a turbine guide wheel which is mounted rotatably relative to the turbine wheel. In order to be able to improve the response of the internal combustion engine after a positive load change without any impairment of the overall efficiency of the internal combustion engine, it is proposed to provide at least one braking device which reduces the speed of the turbine guide apparatus in higher load.
