Abstract
The cap plate has an axially recessed region with a shoulder. The gas guiding ring half shells have a respective projecting rib. A retaining ring consisting of two retaining ring halves abuts with its first leg in the shoulder and is connected by means of fillister head screws to the cap plate. The gas guiding ring half shells are positioned with respect to the cap plate with clearance fit in the radial and axial direction. The ribs have a spacing in the peripheral direction at the separation place of the gas guiding ring half shells in order to form gaps. At the same location, the first leg of the retaining ring halves is interrupted for the formation of recesses aligned with the gaps. Fixing wedges are inserted in the region of the gaps and of the recesses and are screwed to the cap plate. These fixing wedges transfer the tangential forces from the gas guiding ring half shells to the retaining ring halves.
