ABSTRACT:
This device is aimed at solving the problem of varying sealing gaps between a rotatable turbine disc and fixed structure. Axial movement of the turbine disc relative to the fixed casing causes a ring coaxially carried in air bearings on the turbine disc for relative rotation and movement therewith, to operate at least one lever which in turn rotates a shaft. Rotation of the shaft operates further levers to cause seal rings operatively supported thereby, to precisely follow the axial movement of the turbine disc.
