Abstract

Valve de frein, insérée dans le circuit hydraulique à centre ouvert d'un véhicule. La valve de frein 1 comporte un tiroir de distribution 8, qui isole l'orifice de sortie 19 vers la canalisation de freinage 20 de la canalisation de retour 16, 17 et le relie à l'orifice d'entrée 14, en fonction de la pression de freinage commandée, ainsi qu'un tiroir de commande, étranglant le circuit à centre ouvert en fonction de sa réduction de charge, pendant la phase d'élévation de la pression dans l'orifice de sortie 19.
