Abstract (en)
[origin: US4492167A] A partially combustible propellant charge igniter in which combustible ignition-conducting tubes can be more advantageously separated. The igniter includes a metallic bottom piece accommodating an igniter charge therein, a centrally arranged ignition gas guide chamber in communication with the igniter charge for guiding ignition gas therefrom and a combustible ignition-conducting tube accommodating a propagation charge. The ignition-conducting tube is inserted into the bottom piece and extends outwardly therefrom with the propagation charge being arranged in the region of the ignition-conducting tube which extends outwardly from the bottom piece. The igniter includes at least one cavity accommodating a separating charge and being at least partially delimited by a wall of the ignition gas guide chamber and the ignition-conducting tube inserted in the bottom piece, and a nozzle for establishing a communicating connection of the cavity to the portion of the ignition-conducting tube accommodating the propagation charge. The nozzle enables the escape of gases produced by the separating charge after ignition of the separating charge.
