Abstract

L'invention concerne une vanne pour des tuyaux flexibles sous pression pour empêcher l'échappement d'un fluide sous pression lors de la rupture du tuyau après la vanne. Selon l'invention, elle comprend un piston 7 mobile dans un cylindre 6 contre l'action d'un ressort de compression 8, ce piston, lors d'une contre-pression dépassant la force du ressort, étant maintenu vers l'arrière pour établir une connexion principale à travers la vanne, et quand la contre-pression cesse, il est déplacé par le ressort de compression vers une autre position fermant la connexion principale à travers la vanne L'invention s'applique notamment aux tuyaux d'air comprimé, de vapeur ou de liquides sous pression.
