The seal according to the invention comprises two sealing components of circular shape, and substantially concentric, namely: a static sealing component (1) and a dynamic sealing component (4), these two elements being connected to each other by an impermeable diaphragm (14). The component (4) comprises an envelope (5) forming an annular seat containing an elastically deformable annular support (7), against which is clamped a reaction ring (8). The invention makes it possible in particular to centre the support (7) on the reaction ring (8). <IMAGE> |
