Exhaust gas turbocharger with variable turbine geometry for internal combustion engine has at least one adjusting ring guiding element formed with cut away section so that bearing surface protrudes radially beyond guide element

摘要

The exhaust gas turbocharger with variable turbine geometry for an internal combustion engine includes a guide vane adjusting ring (18) guided in bearings (20) installed on the guide vane support (10). Side guiding elements (24) on the bearings are provided for the adjusting ring, with at least one formed with at least one cut away section in the circumferential direction in such a way that the bearing component forming the bearing surface protrudes outwards beyond the guide element in the radial direction or at least terminates flush with it.
