Title (EN) VALVE SYSTEM AND METHOD FOR CONTROLLING THE SAME
(FR) SYSTÈME DE CLAPET ET PROCÉDÉ DE COMMANDE ASSOCIÉ
Abstract:
(EN) A valve system includes an isolation check valve delivering pneumatic fluid as a supply pressure, a double-check valve adapted to deliver a braking demand control signal of the pneumatic fluid based on a higher of a first braking demand in a first pneumatic braking circuit and a second braking demand in a second pneumatic braking circuit, and a control module. The control module is adapted to receive the supply pressure as a control module supply pressure of the pneumatic fluid, receive a control module control pressure of the pneumatic fluid based on the braking demand control signal, and deliver a control module delivery pressure of the pneumatic fluid based on the control module supply pressure and the control module control pressure. A tractor protection module delivers the pneumatic fluid at the control module delivery pressure based on a trailer park brake pressure of the pneumatic fluid.
(FR) L'invention concerne un système de clapet comprenant un clapet anti-retour d'isolement distribuant un fluide pneumatique en tant que pression d'alimentation, un double clapet anti-retour conçu pour émettre un signal de commande de demande de freinage du fluide pneumatique sur la base d'une demande de freinage supérieure entre une première demande de freinage dans un premier circuit de freinage pneumatique et une seconde demande de freinage dans un second circuit de freinage pneumatique, et un module de commande. Le module de commande est conçu pour recevoir la pression d'alimentation en tant que pression d'alimentation de module de commande du fluide pneumatique, recevoir une pression de commande de module de commande du fluide pneumatique sur la base du signal de commande de demande de freinage et délivrer une pression de distribution de module de commande du fluide pneumatique sur la base de la pression d'alimentation de module de commande et de la pression de commande de module de commande. Un module de protection de tracteur distribue le fluide pneumatique à la pression de distribution de module de commande sur la base d'une pression de frein de stationnement de remorque du fluide pneumatique.
