- the sealing blades are preferably one-sided, that is attached to only one sealing segment. So that their free ends always rest against the contact surfaces of adjacent sealing segments, they are in particular elastically deformable or flexible and in particular curved.
- the respective sealing lamellae extend transversely to the flow direction of a working medium flowing in the turbine or
- the respective sealing lamellae are at an angle of less than 90 ° from flat surfaces of the relevant side wall sections or sealing side wall sections. This leads to a particularly suitable elastic deformability of the slats, if two sealing segments of the arrangement tion during assembly are assembled and thereby get the sealing blades biased on the contact surfaces of the adjacent sealing segment to concern. A compression of the sealing blades is thus avoided.
- the sealing lamellae are arched towards their free end.
- the sealing element is designed as a honeycomb construction.
