Abstract (en)

The fire extinguisher, containing a solid or liquid extinguishing substance discharged by a propellant gas such as carbon dioxide, has a pyrotechnically-controlled perforator (6) to pierce a seal or disc (8) on the propellant gas cartridge (9). The perforator is actuated by a pyrotechnic cartridge (4). The fire extinguisher, containing a solid or liquid extinguishing substance discharged by a propellant gas such as carbon dioxide, has a pyrotechnically-controlled perforator (6) to pierce a seal or disc (8) on the propellant gas cartridge (9). The perforator is actuated by a pyrotechnic cartridge (4) delivering a sufficient quantity of gas into an expansion chamber (5) to enable it to pierce the seal or disc, and it is operated by a spring-loaded mechanical striker (1) held in the disarmed position by a removable pin (3).
