Title (EN) A CONTROL VALVE AND METHOD FOR OPERATING A CONTROL VALVE FOR A RAIL CAR BRAKE SYSTEM
(FR) SOUPAPE DE COMMANDE ET PROCÉDÉ DE FONCTIONNEMENT D'UNE SOUPAPE DE COMMANDE POUR UN SYSTÈME DE FREINAGE DE VÉHICULE FERROVIAIRE
Abstract:
(EN) A control valve includes a diaphragm with a flow path with a predetermined cross-section from a brake pipe to a first side of the diaphragm and another flow path having another predetermined cross-section from a second side of the diaphragm to atmosphere. A dump valve prevents flow from the brake pipe to atmosphere. A method for operating a control valve includes supplying brake pipe air to a first side of a diaphragm through a flow path having a predetermined cross-section and permitting or preventing reference air flow to atmosphere through another flow path having another predetermined cross-section. The method further includes supplying reference air to a dump valve that prevents brake pipe air flow to atmosphere.
(FR) L'invention concerne une soupape de commande qui comprend une membrane ayant un trajet d'écoulement ayant une section transversale prédéterminée d'un tuyau de frein vers un premier côté de la membrane et un autre trajet d'écoulement comportant une autre section transversale prédéterminée d'un second côté de la membrane vers l'atmosphère. Une soupape de décharge empêche l'écoulement provenant du tuyau de frein vers l'atmosphère. Un procédé de fonctionnement d'une soupape de commande consiste à fournir de l'air de tuyau de frein à un premier côté d'une membrane par l'intermédiaire d'un trajet d'écoulement comportant une section transversale prédéterminée et à permettre ou à empêcher un écoulement d'air de référence vers l'atmosphère par l'intermédiaire d'un autre trajet d'écoulement comportant une autre section transversale prédéterminée. Le procédé consiste en outre à fournir de l'air de référence à une soupape de décharge qui empêche un écoulement d'air de tuyau de frein vers l'atmosphère.
