Abstract

L'invention concerne un dispositif pyrotechnique de découpage de précision. Un collier 8 en un matériau élastique est muni d'un logement 10 dans lequel entre un cordeau detonant à effet de charge creuse. Ledit collier est placé sur le tube 7 à découper avec interposition d'un isolant thermique 15. Le détonateur 13 est placé dans un dispositif de fixation 12 et est mis en contact avec la partie dorsale du cordeau détonant par une échancrure 33 dans la partie extérieure du collier. Un moyen d'étanchéité 16 peut être prévu entre le collier 8 et l'isolant thermique 15. Applications : circuits de refroidissement, de dépressurisation, systèmes de sécurité.
