Abstract

L'invention concerne une vanne de contrôle de pression pour freinage hydraulique, comprenant une première entrée et une sortie reliées à un premier circuit de pression et une seconde entrée reliée à un second circuit de pression. Selon l'invention, un mécanisme à vanne comprend un siège de vanne 13c dont le passage du liquide d'un premier piston et un organe de vanne 23 retenu normalement en une position prédéterminée dans un corps principal 1 de la vanne de contrôle; un plongeur 20 est disposé avec une surface faisant face au premier piston 16 avec un ressort de contrôle de pression 21 entre eux, son autre surface recevant la pression du liquide dans les entrées 3, 5 et la sortie 4; une vanne à inertie 31, 32 est disposée pour interrompre l'alimentation en liquide vers l'autre surface du plongeur à une décélération prédéterminée. L'invention s'applique notamment à l'industrie automobile.
