Abstract

Ce dispositif comprend un robinet de frein 11 qui se compose essentiellement d'une soupape commutatrice 13 et d'une soupape pilote 14. Ce robinet contrôle la pression de freinage pour un frein de remorque 22 et assure également l'alimentation en fluide de pression d'un utilisateur 19. L'orifice de sortie 31 vers le frein de remorque 22 communique avec le retour 28 à travers un point d'étranglement supplémentaire 36. Cette disposition évite l'élévation de la pression du frein de remorque 22 au-delà de la pression de freinage maximale lorsque la pression dans l'orifice de sortie 29 vers l'utilisateur 19 est élevée et elle amortit les chocs de réaction sur la pédale de frein.
