ABSTRACT:
A device for actuating an ignition mechanism of an oxygen-releasing mechanism in a respirator, with a striker spring fastened in a mounting support and with a striking hammer, which is located at the free end of the striker spring and actuates the ignition mechanism. The striking hammer can be released several times in succession, whereby the replacement of the cartridge is facilitated. The device is provided with a release lever, which can be pivoted from a starting position around a fixed axis and has a tensioning tongue, which extends, at least partially, below the free end of the striker spring and deflects the striker spring in the pretensioning direction. The release lever has a return member automatically restoring the starting position. The mounting support and the axis are fastened to the receiving housing of the respirator, which accommodates the cartridge.
