DEVICE FOR SEALING BETWEEN TWO ANNULAR WALLS OF AN AIRCRAFT ENGINE

摘要

The invention relates to a sealing device between two annular walls (9, 10) of an aircraft engine, the two walls, radially inner (9) and outer (10) respectively, being engaged coaxially with one another. other around a common axis (X), characterized in that: the outer wall (10) comprises an axial end (15) of substantially U-shaped section parallel to the X axis, the opening of which is oriented axially in one direction, - the inner wall (9) comprises an axial end (11) of substantially U-shaped section parallel to the axis X whose opening is oriented axially in an opposite direction, U-shaped end (15) of the outer wall (10) having a free annular edge (18) axially engaged in the opening of the axial end (11) of the inner wall (9), and the end (11) U-shaped of the inner wall (9) having a free annular edge (14) axially engaged in the opening of the axial end (15) of the outer wall (10), so that said walls define between them an annular gas passage of substantially S-shaped axial section.
