Abstract

L'invention concerne un passage tournant (10) sans interruption, de structure simple, à durée de vie élevée et à faible résistance, pour câbles, flexibles ou similaires. Ledit passage tournant présente un boîtier comportant deux parties de boîtier (12A; 12B) pouvant tourner autour d'un axe de rotation relativement l'une à l'autre et définit un espace de réception (13A; 13B) sensiblement cylindrique autour de l'axe de rotation (A). A l'intérieur de l'espace de réception s'étendent sans interruption une ou plusieurs lignes (ou un ou plusieurs conduits) avec deux brins (14A, 14B) coudés autour de l'axe de rotation (A) ainsi qu'un coude de renvoi (15) reliant lesdits brins (14A, 14B), lequel s'étend de manière courbe autour de l'axe de rotation (A) et cintré sensiblement en U autour d'un axe de renvoi perpendiculaire à l'axe de rotation. Le boîtier présente une paroi extérieure (16A, 16B) cylindrique. La paroi extérieure (16A, 16B) cylindrique prédéfinit la courbure des brins (14A, 14B) et du coude de renvoi (15) autour de l'axe de rotation (A) et est formée, au moins sur un segment axial correspondant, par respectivement une des parties de boîtier (12A; 12B).
