Abstract

Ce maître-cylindre comporte deux pistons 14, 15. L'alimentation en fluide de l'un des pistons 15 est commandée par un distributeur à retard qui comprend un obturateur 52A commandé par le piston 15 et fermant initialement l'orifice de sortie 32 après que le piston se soit déplacé d'une courte distance. Un plongeur 41 se déplace contre l'action d'un ressort de commande 51 pour ouvrir de nouveau l'alimentation vers l'orifice de sortie au-dessus d'une pression prédéterminée. Ce maître-cylindre est destiné à être utilisé dans un dispositif de freinage à circuit divisé qui comporte des freins à disques et des freins à tambours et dans lequel l'alimentation en fluide des freins à disques est retardée tandis qu'une pression efficace est développée dans les freins à tambours.
