Abstract

Moteur (10) d’axe longitudinal (X-X’) comprenant un premier élément de rotor (12), un deuxième élément de rotor (16), un premier arbre d’entrainement (14) relié à un compresseur et un organe d’étanchéité (20) disposé axialement entre les deux éléments de rotors (12, 16). L’organe d’étanchéité (20) comprend un disque d’étanchéité (22) comprenant une première portion de fixation (22b) fixée aux deux éléments de rotor (12, 16), et au moins un élément élastiquement déformable (26, 28) fixé à une deuxième portion de fixation (22d) du disque d’étanchéité, ledit élément élastiquement déformable (26, 28) portant au moins deux éléments d’étanchéité (28, 29) respectivement en contact avec le premier arbre d’entraînement (14) et avec le deuxième élément de rotor (16).
