Abstract
An exhaust gas turbocharger has a movable control piston in a turbine casing. The piston is made up of a circular cylindrical body, subjected to exhaust gas pressure, or external pressure and a volute body. The volute body has substantially the cross section of the inlet volute space and adjusts the volume of the latter to the current exhaust gas flow in order to achieve optimum torque variation over the load range of the engine.
