Abstract (en)
[origin: CA3060182A1] The invention relates to a sealing device for use between a rotor part and a stator part, comprising at least one abradable coating (46) interacting with at least two upstream and downstream rubbing strips. Axially upstream of the rubbing strips, the sealing device comprises a circumferential wall (54) which extends radially beyond the free axial sealing surface upstream (48a) of the coating (46), in order to release the circulating gas at the free end of the upstream rubbing strip.
