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. |

DETAILED DESCRIPTION We claim: 1.
A partially combustible propellant charge igniter comprising 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, a combustible ignition-conducting tube accommodating a propagation charge, the ignition-conducting tube being inserted into the bottom piece and extending outwardly therefrom, the propagation charge being arranged in the region of the ignition-conducting tube extending outwardly from the bottom piece, 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 portion inserted in the bottom piece, and nozzle means for establishing a communicating connection of the cavity to the portion of the ignition-conducting tube accommodating the propagation charge, the nozzle means enabling the escape of gases produced by the separating charge after ignition of the separating charge.
2.
A partially combustible propellant charge igniter according to claim 1, wherein the ignition gas guide chamber is provided with a first diameter and the ignition-conducting tube is provided with a second diameter, the second diameter being larger than the first diameter.
3.
A partially combustible propellant charge igniter according to claim 1, wherein a metal plate is provided adjacent the ignition-conducting tube in the region of the cavity and facing the interior of the cavity.
4.
A propellant charge igniter according to claim 1, wherein the nozzle means has a width between 0.
2 and 0.
7 mm.
5.
A partially combustible propellant charge igniter according to claim 1, wherein the cavity is configured as an annular hollow chamber.
6.
A partially combustible propellant charge igniter according to claim 5, wherein the separating charge accommodated in the cavity is configured as annular pill members.
7.
A partially combustible propellant charge igniter according to claim 5, wherein the nozzle means is configured as an annular nozzle
