Abstract

Dispositif d'actionnement hydraulique à entrée numérique comprenant un organe mobile de sortie rappelé vers une position neutre et susceptibles de se déplacer vers l'une ou l'autre de deux positions de travail sous l'action de moyens hydrauliques antagonistes, eux-mêmes contrôlés par des organes de commande de type binaire; pour créer deux positions de travail supplémentaires de l'organe mobile de sortie 10, l'invention prévoit que chacun des moyens d'actionnement se compose de deux surfaces actives (s1 , s'1 ; s2 , s'2 ) agissant successivement sur l'organe de sortie 10, et que la mise sous pression de la première surface soit provoquée par l'un des organes de commande (EV1 , EV2 ) tandis que celle de l'autre surface l'est par l'autre organe de commande à condition que l'organe de sortie air déjà accompli un premier pas de déplacement dans le sens voulu. Application notamment à la commande de vérins hydrauliques à double effet et à deux vitesses de déplacement dans chaque sens.
