Abstract

Valve-relais de remorque comportant un double piston d'action et de réaction dont la surface de réaction est divisée en deux sections isolées délimitant une chambre de réaction primaire et une chambre de réaction secondaire. La chambre de réaction secondaire 14 est reliée à la sortie 10 de la valve par un orifice calibré 16. Application de l'invention au freinage des trains-routiers tels que les ensembles tracteur-remorque ou semi-remorque ou tandem double.
