To create a seal between two components (1, 2) whilst allowing a limited relative rotation of the components about a predetermined axis (4), a bellows (11) is used, comprising two tubular end sections (51, 52), these sections being rigid and sealed to respective zones of one and the other of said components (1, 2), and an intermediate tubular section (53), between said tubular end sections (51, 52), capable of deforming under torsion about said axis (4), through an amplitude at least equal to said limited amplitude. This eliminates all risk of leaks between the two components. <IMAGE> |
