Title (EN) SEQUENCING VALVE FOR A BRAKE CYLINDER HAVING AN AUTOMATIC PARKING BRAKE
(FR) SOUPAPE DE SÉQUENCE POUR UN CYLINDRE DE FREIN PRÉSENTANT UN FREIN DE STATIONNEMENT AUTOMATIQUE
Abstract:
(EN) A sequencing valve for an automatic parking brake. The sequencing valve has a housing with a first port for communication with a source of a brake pipe pressure, a second port for communication with an exhaust, and a third port for communication with a brake pipe pressure input of an automatic parking brake. A valve body in the housing is moveable to either isolate the brake pipe pressure from the input to the parking brake, or couple brake pipe pressure to the input so that the parking brake may be released. A pilot is interconnected to the valve body for moving the valve body from the first position to the second position and can be driven by a charging and partial release of brake pipe pressure, charging of brake cylinder pressure, or a pneumatic signal provided by an electrical or a pneumatic control valve.
(FR) La présente invention concerne une soupape de séquence pour un frein de stationnement automatique. La soupape de séquence présente un logement avec un premier orifice pour communiquer avec une source d'une pression de conduite de frein, un deuxième orifice pour communiquer avec un échappement, et un troisième orifice pour communiquer avec une entrée de pression de conduite de frein d'un frein de stationnement automatique. Un corps de soupape dans le logement est déplaçable soit pour isoler la pression de conduite de frein par rapport à l'entrée du frein de stationnement, soit pour accoupler la pression de conduite de frein à l'entrée de telle sorte que le frein de stationnement peut être desserré. Un pilote est raccordé au corps de soupape pour déplacer le corps de soupape de la première position à la seconde position et peut être entraîné par une charge et une libération partielle de la pression de conduite de frein, une charge de la pression de cylindre de frein, ou un signal pneumatique fourni par une soupape de commande électrique ou pneumatique.
