Abstract

La valve de sécurité de la présente invention comporte, dans un corps de valve 1 un manchon 9, et à l'intérieur de celui-ci un piston 10, ledit manchon étant verrouillé en position ouverte par un dispositif de verrouillage 12 tant que les variations de pression sur lesdits circuits hydrauliques restent dans des limites prédéterminées. Dès qu'il se produit une rupture de canalisation dans le circuit protégé par la valve, le manchon 9 obture la canalisation de sortie 5 et empêche une chute de pression trop rapide.
