Abstract

Clé hydraulique pour le serrage et le desserrage d'organes filetés d'assemblage, tels qu'écrous et boulons, du type comprenant un arbre à section polygonale et une douille adaptable sur une extrémité de cet arbre. L'arbre porte une roue à rochet solidaire en rotation dudit arbre et dont l'actionnement est assuré par un vérin à double effet Il grâce à un cliquet monté entre les extrémités d'un premier jeu de deux leviers parallèles dont une extrémité est articulée sur ledit arbre. Un second jeu de deux leviers parallèles a également une extrémité montée pivotante sur cet arbre tandis que le vérin il pivote par ses extrémités respectivement sur les extrémités opposées des premier et second leviers, de telle sorte qu'au cours du mouvement alternatif du piston du vérin l'arbre et la douille exécutent des mouvements de rotation partielle pour serrer ou desserrer l'organe d'assemblage N engagé dans la douille; un organe de reaction 31 est prévu pour immobiliser la clé pendant son utilisation. Clé destinée notamment aux serrage et desserrage d'organes placés relativement près les uns des autres.
