Abstract

L'invention concerne la mecanique. Elle concerne notamment un dispositif de sécurité pour la distribution d'un fluide sous pression pour l'actionnement d'un appareil ou d'une machine caractérisé en ce qu'il est constitué d'un corps 1 comportant un embout amont 2 et un embout aval Il, d'un piston 28 mobile dans le corps et présentant des ouvertures 34 de mise en communication de l'embout amont avec l'embout aval, d'un siège 21 situé en aval du piston et avec lequel celui-ci est susceptible de coopérer pour obturer les ouvertures 34, et des moyens élastiques tendant à écarter le piston du siège. L'invention s'applique, en particulier, aux machines et appareils entraînés par un fluide sous pression.
