Charging device, particularly exhaust gas turbocharger for internal combustion engine of motor vehicle, has variable turbine- or supercharger geometry and blade bearing ring with rotatably mounted guide blades

摘要

The charging device has a variable turbine- or supercharger geometry and a blade bearing ring with rotatably mounted guide blades. An adjustment ring (1) is provided which is connected with the individual guide blades by output contours (2) and with a control equipment by actuation contours (3). The adjusting ring has multiple actuation contours corresponding to the output contours. The output contour and the drive contour are distributedly arranged in a rotationally symmetrical manner.
