Abstract

L'invention concerne des procédés pour régler avec précision et sans inconvénient la longueur d'un dispositif d'entraînement automatique à une longueur désirée, afinde permettre la manipulation télescopique d'un tuyau d'aspiration par le dispositif automatique (B). Le réglage d'une rallonge de tuyau d'aspiration à une longueur désirée peut être effectué de manière rapide et précise, et cette longueur maintenue de façon stable contre les chocs extérieurs. Cette opération de réglage s'effectue par une opération simple de commutation réalisable avec un seul doigt. Dans une forme de réalisation, un mécanisme de couplage par engrenage assurant l'extension ou l'escamotage de la rallonge de tuyau d'aspiration au moyen d'un pignon (10) et d'un engrenage à crémaillère (6) est mis en oeuvre avec le dispositif d'entraînement automatique. Dans une autre forme de réalisation, un mécanisme de couplage par vis assurant l'extension ou l'escamotage de la rallonge de tuyau d'aspiration au moyen d'une tige filetée (2) et d'une vis creuse est mis en oeuvre avec le dispositif d'entraînement automatique.
