Abstract

Invention concernant une commande hydraulique. Cylindre oléo-pneumatique de commande à deux chambres séparées par une paroi percée d'ouvertures calibrées. Dans l'une des chambres se déplace un piston avec tige, commandé pneumatiquement, qui chasse de l'huile dans l'autre chambre au travers desdites ouvertures, en gouvernant le déplacement du piston Sa tige porte un obturateur à position longitudinale réglable qui vient obturer une partie desdites ouvertures, de manière à ralentir l'avance du piston. Application à la commande d'outils devant être entraînés avec une vitesse d'approche rapide et une vitesse de travail lente.
