Abstract
The seal prevents any particles absorbed by the turbo jet engine from sliding between the upper surface of the disk (1) of the high pressure turbine and the labyrinth (2) secured to the latter. This seal includes a body (5C) placed in a cavity (6) of the labyrinth (2) and a lip (5L) resting on the upper surface (1AM) of the disk (1) so that on stopping there is a small space (6) between the labyrinth (2) and the seal (5). Application for all aircraft turbo jet engines. FIG. 2.
