A relay valve (10) for a compressed-air brake system of a commercial vehicle comprises a control piston (14) arranged in a housing (12) and being axially movable by means of a control pressure supplied from a control port (20); a valve means (24) comprising a valve body (28) being axially movable by means of an axial movement of said control piston (14), wherein said valve body (28) controls fluid connection between a supply port (26) and an outlet port (22); and a movement limiting mechanism (38) configured to limit an axial movement range of said control piston (14) if required.

    Une valve-relais (10) pour un système de frein à air comprimé d'un véhicule utilitaire comprend un piston de commande (14) agencé dans un boîtier (12) et axialement mobile au moyen d'une pression de commande fournie à partir d'un orifice de commande (20); un moyen formant valve (24) comprenant un corps de valve (28) axialement mobile au moyen d'un mouvement axial dudit piston de commande (14), ledit corps de valve (28) commandant un raccordement de fluides entre un orifice d'alimentation (26) et un orifice de sortie (22); et un mécanisme de limitation de mouvement (38) configuré pour limiter une plage de mouvement axial dudit piston de commande (14) si nécessaire.
