Beschreibung
Zusammenfassung:	The invention relates to a railway braking system (1) comprising a first pneumatic distribution device (51) formed by a first distributor provided with a single inlet opening (54a,b) connected to a source for supplying pneumatic pressure mediums (73) and with a single outlet opening (55a,b) connected to a parking brake chamber (25) in order to optionally supply a parking brake (7) with a second pneumatic pressure medium so as to place said brake in either of inoperative and operative configurations, and a second pneumatic distribution device (61) formed by a second distributor provided with a single inlet opening (64a,b) connected to said supply source and with a single outlet opening (65a,b) connected to a service pressure chamber (13) in order to supply a service brake (6) with a third pneumatic pressure medium of which the pressure value is predetermined, so as to apply a predetermined braking force when said parking brake is in the operative configuration thereof. L'invention concerne un système de freinage ferroviaire (1) comportant un premier dispositif de distribution pneumatique (51) formé par un premier distributeur pourvu d'un unique orifice d'entrée (54a,b) connecté à une source d'alimentation en agents de pression pneumatique (73) et d'un unique orifice de sortie (55a,b) connecté à une chambre de frein de parking (25) afin d'alimenter ou non un frein de parking (7) avec un deuxième agent de pression pneumatique pour le mettre respectivement dans des configurations de repos et de travail, et un second dispositif de distribution pneumatique (61) formé par un second distributeur pourvu d'un unique orifice d'entrée (64a,b) connecté à ladite source d'alimentation et d'un unique orifice de sortie (65a,b) connecté à une chambre de pression de service (13) afin d'alimenter un frein de service (6) avec un troisième agent de pression pneumatique dont la valeur de pression est déterminée, de sorte à appliquer un effort de freinage déterminé lorsque ledit frein de parking est dans sa configuration de travail.
