Abstract

L'invention concerne les commandes des machines à usiner les matériaux. La commande hydraulique faisant l'objet de l'invention est caractérisée en ce qu'elle comporte une chambre 3 remplie de liquide moteur, dont le volume est au moins égal à la quantité de liquide consommée par l'appareil utilisateur 23, et qui est divisée par le piston 4 en deux cavités dont l'une communique avec l'accumulateur 1 par une canalisation 5 comprenant une pompe 2, tandis que l'autre est reliée à la pompe par l'intermédiaire d'une canalisation et d'une valve de retenue 24, et à l'appareil utilisateur, par l'intermédiaire d'un dispositif de fermeture 13. L'invention s'applique notamment aux commandes hydrauliques des presses et des marteaux-pilons.
