Abstract

L'invention concerne un dispositif à énergie hydraulique (100) qui comprend un équipement auxiliaire de pression (140) et un générateur de limitation de flux (120) raccordé audit équipement auxiliaire de pression (140). Le générateur de limitation de flux (120) comprend : un réservoir de stockage de fluide comportant un orifice d'admission de fluide et un orifice d'évacuation de fluide ; un piston générateur de limitation de flux (123) coulissant de manière hermétique dans le réservoir de stockage de fluide ; une tige de traction (135) raccordée entre ledit équipement (140) et ledit piston (123). Ladite tige (135) transfère la force d'action produite par l'équipement auxiliaire de pression (140) au piston générateur de limitation de flux (123) de façon à le faire coulisser, ce qui déverse ainsi le fluide dans ledit réservoir à partir de l'orifice d'évacuation de fluide et génère la puissance hydraulique.
