Abstract
Circuit hydraulique de freinage d'un véhicule comprenant au moins un cylindre hydraulique 24 relié à une timonerie de frein, et un dispositif qui commande l'alimentation de ce cylindre en fluide hydraulique sous pression. Il comporte une première soupape 38 de détente qui règle la pression à laquelle le fluide est introduit dans le cylindre 24, sur le côté du piston 25 opposé à celui soumis à la force d'un ressort 27 de serrage des freins, et une seconde soupape 34 de détente qui alimente le cylindre 24 en fluide sous pression, sur le côté du piston 25 soumis à la force du ressort. Domaine d'application : tramways, etc.
