Abstract
The guiding device of a turbine has guide vanes which are rotatably mounted in the turbine housing. A sealing sleeve is arranged between the turbine housing and the guide vane stem. The additional axial compression spring ensures that the sealing sleeve is continuously pressed onto the guide vane mating contour, and that the axial gap and also the leakage flow are prevented as a result.
