Abstract

A flash guide tube arrangement utilized primarily in propellant charge igniters for large-caliber ammunition with laterally located openings from which the ignition gases, emitted by conventional ignition systems, exit, either for the ignition of an ignition booster charge or for the direct ignition of a propellant charge. Indentations emanate axially from these openings and extend into the interior of the flash guide tube, the depth of the individual indentations decreasing in the direction toward the rear end of the flash guide tube. The indentations are preferably radially arranged and several of such radially disposed indentations can be provided in the flash guide tube. The rear end of the flash guide tube can furthermore be constructed as a cone having its apex pointing toward the ignition system.
