Title (EN) BRAKE CYLINDER MAINTAINING VALVE WITH IMPROVED PRESSURE REGULATION
(FR) CYLINDRE RÉCEPTEUR MAINTENANT UNE SOUPAPE AVEC UNE RÉGULATION DE PRESSION AMÉLIORÉE
Abstract:
(EN) A brake cylinder maintaining system that combines a brake cylinder maintaining check valve and a quick service limiting valve into a single unit to have lower hysteresis, and thus more precise BCM regulation pressure and a smaller pressure offset. The check valve and quick service valve are coupled to provide a single system having multiple valve seats for selective communication between quick service pressure and brake cylinder pressure on one hand, and between a brake cylinder maintaining pressure and brake cylinder pressure on the other hand.
(FR) L'invention concerne un système de maintien de cylindre récepteur qui combine un cylindre récepteur maintenant un clapet de non-retour et une soupape régulatrice de service rapide en une seule unité afin d'avoir une plus faible hystérésis, et, ainsi, une pression de régulation de BCM plus précise et un décalage de pression plus petit. Le clapet de non-retour et la soupape de service rapide sont raccordés pour fournir un système unique ayant de multiples sièges de soupape pour une communication sélective entre la pression de service rapide et la pression de cylindre récepteur, d'une part, et entre une pression de maintien de cylindre récepteur et une pression de cylindre récepteur, d'autre part.
