Patent ID: 8328520

Claim:
A turbocharger with variable turbine geometry (VTG) comprising: a turbine housing with a feed passage for exhaust gases; a turbine rotor, which is rotatably mounted in the turbine housing; and a guide vane cascade, which encloses the turbine rotor radially on the outside, which has a vane bearing ring, which has a multiplicity of guide vanes, each of which has a vane shaft which is mounted in the vane bearing ring, which has an adjusting ring which is in functional communication with the guide vanes via associated vane levers which are fastened by one of their ends on the vane shafts, wherein each vane lever on the other end has a lever head which can be brought into engagement with an associated engagement recess of the adjusting ring, the adjusting ring having an outer peripheral surface, a front face and an end face, the front face facing the vane bearing ring, the end face being opposite the front face and facing away from the vane bearing ring, and which has a stop at least for adjustment of the minimum throughflow between adjacent guide vanes, the stop having an inner end and an outer end, the inner end facing an axis of rotation of the turbine rotor, the outer end being opposite the inner end and facing away from the axis of rotation of the turbine rotor, the stop having a stop body and a projection extending radially outwardly from the stop body, wherein the stop is formed as a separate component which can be fixed in the guide vane cascade and wherein the stop is fixed against rotation on the vane bearing ring and wherein a portion of the projection engages in a slot of the adjusting ring, and wherein at least a substantial portion of the stop body, the projection and the lever heads are located on the end face side of the adjusting ring.
