Abstract An automatic control of clamping forces in primary nozzle systems of radial turbines. Pressure to an closed annular volume positioned between a turbine housing and an axially adjustable mounting ring is varied to regulate the clamping forces against inlet vanes which form primary nozzles. A controller compares process control data with nozzle position data to detect onset of excessive blow-by, in which case pressure is increased in the closed annular volume to move the mounting rings closer together. The controller also compares expected and actual system data to detect onset of excessive clamping, in which case pressure is increased in the closed annular volume to increase clamping forces.
