Abstract

Ensemble pyrotechnique portatif permettant d'aspirer un fluide et notamment de faire le vide dans une enceinte étanche. L'ensemble déprimogène comporte préférentiellement : un corps constitué dune coquille externe, d'une tubulure d'aspiration et de l'éjecteur de la trompe qui se raccordent au collecteur de cette trompe, et d'un dispositif de percussion mécanique, une cartouche pyrotechnique amovible, un dispositif de fixation temporaire de la cartouche sur le corps, qui assure le positionnement relatif d'une part de l'amorce pyrotechnique de la cartouche et du dispositif de percussion mécanique, et d'autre part du générateur pyrotechnique par rapport au collecteur de la trompe. L'invention peut être utilisée pour rigidifier les enceintes souples contenant un matériau granulaire, ainsi que pour intervenir rapidement sur des circuits de fluide devant être amorcés ou purges.
