Abstract

L'invention concerne un allumeur pyrotechnique destiné à allumer des charges pyrotechniques propulsives ou des substances explosives, comprenant un tube guide-flammes (4) utilisé pour assurer un allumage régulier de la charge propulsive, qui est relié à une pièce cylindrique de base (1) et qui peut être vissé dans une grenade pour mortier. Le tube guide-flammes (4) est vissé directement dans la pièce cylindrique de base (1) à l'aide d'un adaptateur (5) fait d'une pièce qui immobilise dans la pièce de base (1) un percuteur (11) et une amorce d'allumage (13). Le tube guide-flammes (4) possède des ouvertures de flammes (8a, 8b) qui assurent l'allumage de la charge propulsive standard (27), placée autour du tube guide-flammes (4) dans la douille (24), par la charge de transmission (9) se trouvant dans le tube guide-flammes (4).
