Adjustable Turbine Nozzle Ring
The cast turbine guide vanes of the adjustable turbine nozzle ring (510.000)
have the same profile as the fixed nozzle ring in order to benefit from the
advantages of low vibration and good flow characteristics.
Adjustment Device
The principal components of the adjustment device are the two spindle
drives (511.001) which are responsible for converting the rotational motion of
the servomotors (512.020) to a linear motion for adjustment of the VTA.
