Railway applications - Braking - Relay valves
This document is applicable to relay valves designated to control the brake cylinder pressure of compressed air brakes fitted to railway vehicles, in association with an air brake distributor valve or other control device. It covers one stage relay valves and relay valves adjusting the brake cylinder pressure in response to a change in vehicle speed or load that is either continuously variable or in two or more stages, i.e. empty – loaded.
Relay valves operating with other pressures, in particular the brake pipe pressure, are not included.
This document specifies the requirements for the design, manufacture and testing of relay valves.
Bahnanwendungen - Bremse - Relaisventile
Dieses Dokument ist anzuwenden für Relaisventile, die zur Steuerung des Bremszylinderdrucks von Druckluftbremsen in Eisenbahnfahrzeugen in Verbindung mit einem Druckluftbremsensteuerventil oder einem anderen Steuergerät bestimmt sind. Es umfasst einstufige Relaisventile und Relaisventile, die den Bremszylinderdruck in Abhängigkeit von einer Änderung der Fahrzeuggeschwindigkeit oder last anpassen, die entweder stufenlos oder in zwei oder mehr Stufen, d. h. leer — beladen, variabel ist.
Relaisventile, die mit anderen Betriebsdrücken, insbesondere dem Druck in der Hauptluftleitung, arbeiten, werden nicht berücksichtigt.
Dieses Dokument legt die Anforderungen für die Konstruktion, die Herstellung und die Prüfung von Relaisventilen fest.
Applications ferroviaires - Freinage - Relais pneumatiques
Le présent document s'applique aux relais pneumatiques conçus pour commander la pression au cylindre de frein des freins à air comprimé montés sur des véhicules ferroviaires, conjointement avec un distributeur de frein à air ou un autre dispositif de commande. Il s'applique aux relais pneumatiques à un étage de pression et aux relais pneumatiques qui régulent la pression au cylindre de frein en fonction des variations de la vitesse ou de la charge du véhicule, soit de manière continue, soit par deux étages de pression ou plus, comme les relais vide/chargé.
Les relais pneumatiques fonctionnant avec d'autres pressions, notamment la pression de conduite générale, ne sont pas inclus.
Le présent document spécifie les exigences relatives à la conception, à la fabrication et aux essais des relais pneumatiques.
Železniške naprave - Zavore - Ventili za kontrolo tlaka (vključuje dopolnilo A1)
Ta dokument se uporablja za ventile za kontrolo tlaka, namenjene nadzoru tlaka v zavornem valju pnevmatskih zavor, nameščenih na železniških vozilih, v povezavi s krmilnim ventilom zračne zavore ali drugo krmilno napravo. Zajema enostopenjske ventile za kontrolo tlaka in ventile za prilagajanje tlaka v zavornem valju kot odziv na spremembo hitrosti vozila ali obremenitev, ki je bodisi zvezno spremenljiva bodisi v dveh ali več stopnjah (tj. prazno – natovorjeno).
Ventili za kontrolo tlaka, ki delujejo z drugimi tlaki, zlasti s tlakom v zavornem vodu, niso vključeni.
Ta dokument določa zahteve za načrtovanje, izdelavo in preskušanje ventilov za kontrolo tlaka.
