Adjustment device for influencing exhaust gas flow parameter at turbine wheel inlet of turbocharger of internal combustion engine of motor vehicle, has guide vane element that is changeable in its upstream and/or downstream flow angles

摘要

The device (30) has a guide vane arrangement (31) provided with a guide vane element (32), and an axial slide (34) arranged within an area of the guide vane arrangement. A flow cross-section of a turbine wheel inlet is adjusted by the axial slide. The guide vane element is changeable in its upstream flow angle and/or its downstream flow angle. The axial slide is arranged in upstream of the guide vane element. The guide vane arrangement is retained in a retaining arrangement of the axial slide.
