Abstract

L'invention a pour objet un dispositif pyrotechnique d'obturation d'une canalisation. Le dispositif d'obturation d'une canalisation se caractérise en ce qu'il comporte un vérin pyrotechnique, deux pièces situées de part et d'autre de ladite canalisation et un système de mise à feu du moyen pyrotechnique de commande dudit vérin. lesdites pièces étant associées audit vérin de façon telle que la mise à feu dudit moyen de commande du vérin projette lesdites pièces l'une à l'encontre de l'autre, de façon à obturer ladite canalisation par écrasement entre ces dernières. Selon l'invention, l'une desdites pièces est solidaire du piston dudit vérin et l'autre pièce est liée mécaniquement, par l'intermédiaire de tirants, à la culasse dudit vérin, ladite pièce solidaire dudit piston étant guidée librement en translation par lesdits tirants. Application à l'obturation de canalisations.
