Abstract

L'invention concerne un dispositif d'accouplement pour des conduites d'alimentation qui sert en particulier à refouler des fluides d'un tracteur routier à une semi-remorque (11) ou inversement. Le tracteur routier et le semi-remorque (11) peuvent accouplés ou désaccouplés au moyen d'une unité d'accouplement (10), laquelle présente une sellette d'attelage (15) dans le cas du tracteur routier et un élément d'appui (22') doté d'un pivot d'attelage (21) dans le cas de la semi-remorque (11). Dans chaque cas, au moins un bloc de raccordement (30, 31), qui comporte plusieurs éléments connecteurs (37, 38, 77, 78), pour raccorder des conduites d'alimentation (33,34,35, 36), est monté en-dessous de la sellette d'attelage (15) et du pivot d'attelage (21). Il est prévu un élément rotatif (20) disposé dans l'élément d'appui et auquel sont fixés ledit au moins un bloc d'accouplement (30, 31) et un dispositif de centrage (25), qui coopère, au moment du raccordement, avec des moyens de centrage dans le cas de la sellette d'attelage (15), de telle sorte que les blocs d'accouplement (30, 31) peuvent être orientés les uns par rapport aux autres, et par conséquent, être reliés. Les conduites d'alimentation (35, 36) partant du bloc d'accouplement (31) dans le cas de la semi-remorque (11) sont guidées par des moyens de liaison (23, 24) dans l'élément rotatif (20) jusqu'aux conduites d'alimentation (35',36') disposées dans la semi-remorque (11). Ledit dispositif d'accouplement destiné à ces conduites d'alimentation, destinées en particulier à assurer l'échange desdits milieux, permet d'obtenir une structure très compacte, laquelle permet un accouplement automatique des conduites d'alimentation lors de l'accouplement de la sellette d'attelage au pivot central.
