Abstract

Le dispositif de maintien se compose d'un ensemble hydraulique d'isolement (2) monté entre les branches d'alimentation d'un vérin (1). Cet ensemble d'isolement (2) comprend un sas (9) présentant à chacun de ses deux orifices un clapet anti-retour dont un clapet primaire (11) en liaison hydraulique avec la chambre de sortie (6) de la tige (7) du vérin (1) monté passant dans le sens vers cette chambre et un clapet de sécurité (13) monté passant dans le même sens, la fermeture de ce dernier étant différée par rapport à celle du clapet primaire (11). Cette invention s'applique au maintien de la tige de tous les vérins notamment sous charge et intéresse les fabricants d'organes hydrauliques, notamment de vérins de levage, ainsi que les utilisateurs.
