Abstract
A seal for reducing a fluid flow around tips of rotating blades of a turbine includes a plurality of diaphragms disposed in succession and providing an outer support for a radial arrangement of static blades disposed alternatingly with the rotating blades in an axial direction. An outer seal has axial and radial supports. The radial support includes a ring held in position by a key and a circumferential extension of the ring. The key and the circumferential extension have a clearance so as to allow a relative radial movement between the ring and a part of a casing or the plurality of diaphragms and providing a pressure sealing face and support in the axial direction.
