摘要：
The rotor of each stage of a turbine is surrounded, with a clearance by a fixed ring, formed by a metal ring supporting internally an annular thermal screen, in the form of ceramic segments. Expansions and contractions of the metal ring under the action of air which is supplied thereto in order to control the said clearance are transformed into displacements of radial faces of the ring in contact with radial flanges rigid with the turbine casing and seals serve to ensure fluidtightness of the ring.
