Abstract

Cette soupape de modulation pour frein hydraulique est intercalée entre le maître-cylindre et le cylindre de frein. En cas d'un blocage de roue elle interrompt la liaison hydraulique ou pneumatique vers le cylindre de frein de roue et abaisse la pression de freinage régnant dans ce cylindre L'organe d'arrêt 3 est réalisé, dans sa partie située à l'opposé de la membrane 6, sous forme d'un piston d'arrêt 31 muni circonférentiellement de plusieurs évidements 311 au niveau du fût de piston pour dégager et obturer les connexions 111, 112 du maître-cylindre HZ et du cylindre de frein de roue RZ, tandis que sa partie 32 entre le piston d'arrêt 31 et la nervure de piston 33 est amincie.
