Abstract

a. Appareil à vérin hydraulique. b. Appareil caractérisé par un tiroir 8 à deux positions pour commuter le vérin hydraulique 1 à double effort et régler la pression du fluide hydraulique dans le sens du travail du vérin pour être au moins supérieure à un seuil et communiquer au piston 30 du vérin une énergie cinétique supérieure à une valeur donnée. c. L'invention s'applique à l'entraînement d'un dispositif servant à frapper ou à déformer une pièce.at. Device with hydraulic cylinder. b. Device characterized by a slide 8 with two positions for switching the hydraulic cylinder 1 with double effort and adjusting the pressure of the hydraulic fluid in the working direction of the cylinder to be at least greater than a threshold and to impart kinetic energy to the piston 30 of the cylinder greater than a given value. vs. The invention applies to the drive of a device used to strike or deform a part.
