ABSTRACT:
An igniter unit for igniting of propellant charges comprises an igniter element operatively associated with a booster charge. The igniter element is arranged within an external housing and the booster charge is provided in an internal housing arranged within the external housing. The internal housing has a closed, lateral wall and a closed base at one end which withstands the ignition pressure generated upon ignition of the igniter element and the booster charge. The internal housing is provided with means for defining openings for causing the cloud of gas produced by ignition to flow from the booster charge and the igniter element to one end, that is the front end, of the internal housing to effect the ignition of the propellant charge.
