Abstract
Cette invention concerne une valve de commande comportant des valves élémentaires réunies en un bloc de commandé 10. Ces valves sont actionnées au moyen d'un arbre à cames 14, 16, 18 par l'intermédiaire d'un levier 15, 17, 20. L'arbre à cames porte au moins une came additionnelle 28, 36, 37 calée sur lui et soumise à l'effet d'un dispositif de rappel ramenant automatiquement l'arbre à cames en position de repos quand on relâche le levier. Cette valve, utilisable en particulier pour un soutènement hydraulique marchant dans les exploitations minières, fournit ainsi une commande d'homme mort.
