Abstract
An exhaust gas turbocharger having rotor runners disposed in roller bearings protects the roller bearings from shocks and vibrations by a pressure-oil-filled oil film damper. By a shut-off device arranged in the main lubricating oil duct, the lubricating oil supply of the roller bearings is shut off when the rotor runners are stopped. However, the pressure oil supply of the oil film damper remains operative so that the oil film damper retains its operability.
