Abstract (en)
The guide vane ring (1) has several rotatable guide vanes (2) with an inner ring (4) for radial inner stabilization of the guide vanes having a seal carrier (6). The seal carrier is arranged radially and inwardly with respect to the inner ring. A spring-like sealing element (58) with an annular C-shaped section, is arranged between an inner ring portion and a seal support portion, so that the inner ring and the seal carrier are clamped to each other. An independent claim is included for turbomachine.
