Sealing ring for sealing the gap between the guide vanes of a guide vane assembly of a stationary axial turbo-machine and his rotor

摘要

The ring (10) has a sealing plate (52) e.g. labyrinth seal, provided between two segments of rings (34, 36). The ring (34) is displaceably attached to the ring (36) in a radial direction. The segments adjacent to each other extend in a peripheral direction over guide vanes of a guide vane assembly. One of the rings has a radially open inner groove (66) and another ring has a hook (46) protruded in the radial direction, where the hook engages in the groove according to connection of the groove and a spring.
