Abstract

L’invention concerne un actionneur hydraulique comprenant une pompe (12) volumétrique à débit variable, un organe (20) permettant de faire varier en continu le débit de la pompe (12), l’organe (20) étant actionné par un vérin (40) alimenté par un premier distributeur (48) commandé en fonction d’un ordre de déplacement de l’actionneur (10). Selon l’invention, l’actionneur (10) comprend un deuxième distributeur (60) commandé en fonction d’une pression de sortie (P) de la pompe (12), le deuxième distributeur (60) comprenant deux positions, l’une (60a) dite repos obtenue tant que la pression de sortie (P) de la pompe (12) est inférieure à une pression prédéterminée et transmettant la sortie du premier distributeur (48) au vérin double effet (40) et l’autre (60b) dite active, transmettant la pression de sortie (P) de la pompe (12) au vérin (40) de façon à réduire la pression de sortie (P) de la pompe (12).
