Abstract (en)
[origin: EP2696039A1] The stage has a guide vane assembly comprising a guide vane with a radially inner guide vane root. A brush-type sealing ring element is supported on the guide vane root by a spoke-type centering. The centering comprises circumferential grooves (2.1, 2.2) for receiving an inner wall (1.2). The inner wall has a front surface (1.4) facing a groove inner surface of the circumferential grooves. An edge (1.5) is fixed adjacent to the inner surface. A rounded portion i.e. radius (R), is formed between the front surface and the edge. The inner wall is provided with a radial groove.
