Abstract
A turbocharger with an improved suspension mechanism for the actuation ring of a variable nozzle mechanism, for improved maintenance of the geometry of the suspension mechanism in the case of extreme temperature oscillations. The suspension mechanism includes a number of guide rollers () provided between housing part () and nozzle ring () with circumferential grooves () in which the inner circumference of the actuating ring rides. The rollers are formed as one piece together with axial extensions (), which extensions are rotatably seated in appropriate bores in the nozzle ring () and/or in the housing part (). The axial extensions can have diameters which are smaller than or the same as the diameter of the actual roller part.
