Abstract

Cette barre du type comprenant un cylindre de vérin 1 et un piston 4 est munie d'un dispositif de verrouillage hydraulique composé de deux clapets logés dans le piston 4 et qui isolent les chambre 3 et 5 du cylindre des conduits hydrauliques 6 lorsque ces derniers sont à la bâche. Une navette hydraulique formant poussoir est intercalée entre les deux clapets pour ouvrir mécaniquement l'un de ces clapets lorsque l'autre est ouvert par la pression de commande du vérin.
