Abstract

Sécateur hydraulique selon le brevet principal, caractérisé en ce que le piston d'entraînement assujetti à la lame mobile dudit sécateur comporte deux faces de travail opposées de surfaces inégales, soit une face de travail de surface réduite délimitant une chambre en relation constante avec l'arrivée du fluide hydraulique sous pression, et une face de travail opposée de surface plus importante délimitant une seconde chambre susceptible d'être mise en communication, soit avec l'arrivée du fluide, soit avec le retour du fluide, au moyen du distributeur hydraulique; ledit sécateur comportant encore un passage permettant d'établir une communication entre les deux chambres délimitées par le piston d'entraînement, lors que le tiroir distributeur est déplacé dans la position de commande de fermeture des lames.
