ABSTRACT:
An ignition unit is provided with an internal housing defining a chamber in which an ignition charge and an ignition element igniting the charge are accommodated. The housing defining the chamber consists of a cover and a container which are connected to one another along a circumferential groove. A distributor housing is mounted on to the housing forming the chamber, in which distributor housing gas outlet openings are provided which are closed by a cap-shaped cover of the chamber. The V-shaped circumferential groove represents a predetermined breaking or separation position of the chamber, for which reason the cover is separated from the container when the ignition charge is ignited. The cover moves away from the container into a space until it strikes the upper end of the distributor housing. With its movement relative to the distributor housing, the cover releases the gas outlet openings so that the gases and flames can emerge from the ignition unit.
