Abstract

a. Dispositif de commande du cylindre principal d'une scie mécanique. b. Ce dispositif est caractérisé en ce que sur l'archet est monté un support avec un galet de refoulement coopérant avec l'extrémité conique d'un piston étagé et en ce que la chambre du piston a une forme annulaire et est limitée du côté du ressort réglable par la partie de grand diamètre D2 du piston étagé et de l'autre côté par la partie de petit diamètre D1 de celui-ci qui présente une gorge intermédiaire cylindrique, et en ce qu'il est relié au moyen d'un conduit hydraulique intermédiaire à la chambre du piston de la pompe hydraulique, dont le ressort de piston prend appui sur une coquille d'arrêt percée d'une ouverture dans laquelle passe la tige de limitation de course montée dans le piston de charge. c. Concerne d'une matière très générale les machines-outils et plus particulièrelent les scies à métaux à commande hydraulique.
