Abstract

Frein hydraulique pour véhicules. Il comprend un maître cylindre avec un volume 6 de pression primaire compris dans un alésage 2 du cylindre entre les pistons 3 et 4 relié aux roues arrière et un volume 8 de pression secondaire défini entre le piston 4 et l'extrémité fermée 5 de l'alésage 2 du cylindre relié aux roues avant. Les forces relatives des ressorts 10 et 11 des pistons 3 et 4 sont choisies de manière que le fluide dans le volume secondaire 8 ne puisse être mis sous pression tant qu'une pression prédéterminée ait été établie dans le volume primaire 6. Application aux freins hydrauliques à maître cylindre en tandem.
