Abstract (en)
[origin: EP1350925A2] The seal device has a heat-elastic inner ring (3) fitted to the blade foot (14) of a turbine blade (1) provided with a dovetail seal (4) cooperating with a labyrinth (5) of the rotor (17). The cooling flow through the turbine blade communicates with a flow channel provided by a bore (15) extending through the inner ring to the dovetail seal, leading to a further flow channel provided by a radial bore (7) or a diagonal bore.
