Abstract

Le circuit comprend : - une pompe (4) ; - au moins un moteur hydraulique (6) ; et - au moins un distributeur proportionnel (20) comprenant un tiroir mobile, le distributeur étant configuré pour faire varier un débit de fluide fourni par la pompe entre des valeurs non nulles proportionnelles à un déplacement du tiroir, le circuit étant configuré pour que la pompe alimente le distributeur en fluide et que le distributeur commande un mouvement du moteur au moyen du débit de fluide.
