Abstract

L'invention concerne une commande pour le soutènement en taille, comprenant une pluralité de soutènements (boucliers 1-18) et de transmetteurs de forces hydrauliques, un appareil de commande de soutènement central pour la commande sélective d'un bouclier particulier parmi la pluralité de boucliers existants, ainsi qu'une commande (34) pour chaque bouclier et des soupapes de commande hydrauliques à actionnement électro-magnétique (soupape pilote et soupape principale) pour les transmetteurs de forces. Les soupapes de distribution, y compris les soupapes pilote et principale, sont directement affectées, également dans l'espace, à leurs transmetteurs de forces, avec lesquels elles sont en liaison hydraulique sans câblage intermédiaire. Chaque commande de bouclier est reliée aux commandes à soupapes (40), lesquelles sont reliées entre elles par un câble de transmission d'instructions seulement bifilaire. Les instructions sont transmises par un mot code pour les aimants de la soupape de commande correspondante, ce mot code étant transmis en série avec ordre d'actionnement.
