Abstract:
One of the components (15), opposite a labyrinth seal (12), is arranged sliding on a conical interface (18) of its support (7, 19) and constructed from a material with different thermal expansions, so as to reduce the clearance with the component face to face (13, 14), at steady state, at high temperature. The sealing surface (25) may be assured by a circulation of oil.
