Abstract

L'invention concerne un joint tournant comportant une première (7, 8) et une seconde (7, 8) parties mobiles l'une par rapport à l'autre autour d'un axe de rotation (A). Les première et seconde parties mobiles (7, 8) comportent chacune une zone d'interface (30) présentant une pluralité d'éléments en saillie et en retrait de formes complémentaires, les éléments en saillie et en retrait de l'une des parties (7, 8) s'imbriquant avec les éléments en saillie et en retrait de l'autre partie (7, 8) de manière à former des chambres de décompression à volume croissant, les zones d'interfaces étant situées à distance l'une de l'autre sans frottement entre elles.
