Abstract
L'INVENTION CONCERNE LA COMMANDE HYDRAULIQUE D'UN VERIN. LE DISPOSITIF COMPORTE UN REGULATEUR. LE REGULATEUR EST PILOTE PAR LA PRESSION DANS LA LIGNE III ET IL EST CONCU ET DISPOSE POUR COMMANDER L'ALIMENTATION DES LIGNES DE PRESSION I ET II. UN MOYEN ANTI-RETOUR 13 EST MONTE SUR LA LIGNE II A L'EXTERIEUR DE LA PORTION DE CETTE LIGNE QUI RELIE LE REGULATEUR AU COTE TIGE DU VERIN 1. APPLICATION AU DEBOURRAGE AUTOMATIQUE D'UNE MECHE POUSSEE PAR LE VERIN.
