Title
(DE) ANHÄNGERSTEUERVENTIL FÜR EINE DRUCKLUFTBREMSANLAGE
(EN) TRAILER CONTROL VALVE FOR A COMPRESSED AIR BRAKING SYSTEM
(FR) VALVE DE COMMANDE DE REMORQUE POUR UN SYSTÈME DE FREIN À AIR COMPRIMÉ
Abstract
(DE)
Die Erfindung betrifft ein Anhängersteuerventil (1) für eine Druckluftbremsanlage mit einer Abrisssicherungs-Ventileinrichtung (2), die einen in einer Längsbohrung (20) längsbeweglichen Schaltkolben (21) aufweist, wobei der Schaltkolben (21) eine erste Kolbenwirkfläche (31) aufweist, die mit einem Steuerdruck beaufschlagbar ist, sowie mit einem mit dem Schaltkolben (21) verbundenen Drosselkolben (25). Hiervon ausgehend wird ein hinsichtlich seines Aufbaus vereinfachtes Anhängersteuerventil angegeben. Hierzu ist vorgesehen, dass der Schaltkolben (21) eine zweite Kolbenwirkfläche (32) aufweist, die mit einem Vorratsdruck beaufschlagbar ist, wobei die erste und die zweite Kolbenwirkfläche (31, 32) einander entgegen gerichtete Betätigungskräfte auf den Schaltkolben (21) ausüben, und die zweite Kolbenwirkfläche (32) einen größeren Durchmesser aufweist als der Drosselkolben (25).
(EN)
The invention relates to a trailer control valve (1) for a compressed air braking system having a breakaway safeguard valve device (2), which has a control piston (21) that can move longitudinally in a longitudinal bore (20), the control piston (21) having a first piston effective area (31) to which a control pressure can be applied, and also having a throttling piston (25) connected to the control piston (21). On this basis, a trailer control valve with a simplified structure is specified. To this end, provision is made for the control piston (21) to have a second piston effective area (32) to which a supply pressure can be applied, wherein the first and the second piston effective areas (31, 32) exert mutually oppositely directed actuating forces on the control piston (21), and the second piston effective area (32) has a larger diameter than the throttling piston (25).
(FR)
L'invention concerne une valve de commande de remorque (1) pour un système de frein à air comprimé comprenant un dispositif de valve de protection contre le détachement (2) qui présente un piston de commutation (21) longitudinalement mobile dans un alésage longitudinal (20), le piston de commutation (21) présentant une surface active (31) qui peut être soumise à une pression de commande, ainsi qu'un piston d'étranglement (25) relié au piston de commutation (21). Partant de là, l'invention fournit une valve de commande de remorque simplifiée du point de vue de sa structure. Selon l'invention, le piston de commutation (21) présente une deuxième surface active (32) qui peut être soumise à une pression de réserve, la première et la deuxième surface active (31, 32) exerçant sur le piston de commutation (21) des forces d'actionnement dirigées l'une contre l'autre, et la deuxième surface active (32) présente un diamètre plus grand que le piston d'étranglement (25).
