Abstract
L'invention concerne un dispositif de coupure pyrotechnique (100) comprenant : une première chambre (14) de mise sous pression en communication avec un initiateur pyrotechnique, une deuxième chambre (15) de coupure dans laquelle est présente une portion conductrice (40), et un piston (30), le piston comprenant un relief de coupure (34), l'initiateur pyrotechnique étant configuré pour faire passer le dispositif de coupure d'une première configuration de passage du courant à une deuxième configuration de coupure de courant, le piston étant mis en mouvement lors du passage de la première à la deuxième configuration afin de rompre la portion conductrice par impact avec le relief de coupure. Le piston définit un canal de soufflage d'arc électrique (3) configuré pour mettre en communication la première chambre avec la deuxième chambre lors du passage de la première à la deuxième configuration et au plus tard au moment de l'impact entre le relief de coupure et la portion conductrice.The invention relates to a pyrotechnic cut-off device (100) comprising: a first pressurization chamber (14) in communication with a pyrotechnic initiator, a second cut-off chamber (15) in which a conductive portion (40) is present, and a piston (30), the piston comprising a cutoff relief (34), the pyrotechnic initiator being configured to change the cutoff device from a first current flow configuration to a second current cutoff configuration, the piston being set in motion during the passage from the first to the second configuration in order to break the conductive portion by impact with the cut-off relief. The piston defines an electric arc blowing channel (3) configured to put the first chamber in communication with the second chamber during the passage from the first to the second configuration and at the latest at the time of impact between the relief of cutoff and the conductive portion.
