Abstract

La présente invention concerne une suspension pour des outils interchangeables à commande hydraulique. L'outil est rapporté sur le bras porte-outils de la machine en même temps que sont réalisées les connexions permettant sa commande. Pour cela le fluide sous pression est amené à l'outil par l'intermédiaire d'une conduite de pression 5 prévue dans la pièce de raccordement du bras porte-outils, d'une soupape 3 actionnée en fonction du déplacement du boulon 2 de ladite pièce de raccordement, d'un alésage 10 prévu dans ledit boulon 2 qui communique avec un canal annulaire il prévu dans l'ouverture de la fouche 1 entourant le boulon 2, et par l'intermédiaire d'un canal prévu dans le boulon qui assure le montage pivotant de l'outil. Ensuite, le fluide de pression est renvoyé vers un réservoir collecteur. L'invention s'applique aux outils interchangeables des dragues hydrauliques.
