Abstract

Installation de freinage à deux conduites (commande du freinage et alimentation) pour remorque, du type comportant une valve-relais disposée dans le circuit de freinage de service entre le réservoir de remorque relié à la conduite d'alimentation. et au moins un cylindre de frein de service. Une deuxième valve-relais d'alimentation 7 du cylindre à ressort 29 est interposée dans le circuit 36, 28 de freinage du cylindre de frein à ressort. Application au freinage d'une remorque par des cylindres de frein à ressort.Two-line brake system (brake control and supply) for a trailer, of the type comprising a relay valve arranged in the service braking circuit between the trailer tank connected to the supply line. and at least one service brake cylinder. A second supply relay valve 7 of the spring cylinder 29 is interposed in the brake circuit 36, 28 of the spring brake cylinder. Application to the braking of a trailer by spring brake cylinders.
