Abstract

Cylindre à ressort, et notamment cylindre de frein à ressort pour véhicules routiers, comportant un accumulateur d'énergie à ressort encastré entre le fond et le piston du cylindre. Le fond 1 est muni d'une rainure spirale 3 pour le logement de la dernière spire 4 d'un ressort à extrémités ouvertes. La rainure commence à son point bas 7 par une butée pour la partie << morte>> de la dernière spire 4 du ressort, puis se poursuit sur une circonférence correspondant au rayon du ressort 6, et en fonction du pas de la dernière spire 4, jusqu'à une zone admissible pour l'application de la force excentrique exercée par le ressort 6.
