Title (EN) PNEUMATICALLY PILOTED RETAINER VALVE FOR RAIL CARS
(FR) VALVE DE RETENUE À COMMANDE PNEUMATIQUE POUR VÉHICULES FERROVIAIRES
Abstract:
(EN) A pneumatically piloted retainer valve (10) for bottling brake cylinder pressure that can be set and released in response to changes in the brake pipe pressure. Pneumatically piloted retainer valve (26) provides a brake cylinder (BC) pressure retaining function that bottles applied brake cylinder pressure in the brake cylinder when brake pipe pressure is less than a predetermined cut-in pressure. Pneumatically piloted retainer valve includes a retainer valve (10) movable between a reset position, where brake cylinder pressure is in communication with exhaust and a bottle position, wherein brake cylinder pressure is isolated from exhaust. A retainer pilot control valve (40) provides for piloting of the retainer valve in response to a predetermined reduction or threshold increase in brake pipe pressure.
(FR) L'invention concerne une valve de retenue à commande pneumatique (10) destinée à embouteiller une pression de cylindre de frein qui peut être appliquée et libérée en réponse à des changements de pression dans une conduite de frein. Une valve de retenue à commande pneumatique (26) fournit une fonction de retenue de pression de cylindre de frein (BC) qui embouteille une pression de cylindre de frein appliquée dans le cylindre de frein lorsque la pression dans la conduite de frein est inférieure à une pression de coupure prédéterminée. La valve de retenue à commande pneumatique comprend une valve de retenue (10) mobile entre une position de réinitialisation, dans laquelle la pression du cylindre de frein est en communication avec l'échappement, et une position d'embouteillage, dans laquelle la pression du cylindre de frein est isolée de l'échappement. Une valve de commande pilote de retenue (40) assure le pilotage de la valve de retenue en réponse à une réduction ou une augmentation de seuil prédéterminée de la pression de la conduite de frein.
