Abstract (en)
[origin: EP2071142A1] The casing (10) has radial arms (16) for connecting a radial inner wall (12) and a radial outer wall (14), and a cylindrical envelope (18) connected to a downstream end of the inner wall. The envelope delimits a hub cavity (38) with the inner wall and an exhaust gas flow space with the outer wall. The envelope has an upstream end with an annular radial part (26) extending towards interior of a turbomachine. The radial part has an inner end comprising an annular edge (28) that co-operates by radial sliding with the inner wall in a sealed manner.
