Abstract (en)
The turbine i.e. high-pressure partial turbine (20), has an inner housing (23) arranged around a rotatably supported rotor (22) and an outer housing (3) e.g. pot-shaped housing, arranged around the inner housing. The inner housing has an inner housing upper part (34) and an inner housing lower part. A shrink collar (4) is provided for compressing the inner housing upper and lower parts. A seal (9) is arranged on the collar, and seals a gap between the collar and outer housing. A segment (8) is provided before the collar. A blading region is provided between the rotor and inner housing.
