Abstract

La présente invention concerne une machine de construction formant drague. Cette machine comportant un essieu pendulaire 1 ainsi que deux cylindres de blocage 4 associés audit essieu, se caractérise en ce que chaque cylindre comprend une soupape d'arrêt qui se feutre par la purge d'une conduite de commande 9 et par l'application d'une bille soumise à l'action d'un ressort de rappel 10 contre le siège 12 de ladite soupape. Au-dessus du siege 12 est prévue une membrane 13 dont la surface, par rapport à la pression de commande dans la conduite 9 permet de déterminer la pression hydraulique dans la cavité du cylindre 4. L'invention donne une meilleure assise aux dragues.
