<p>In a trigger mechanism for automatic fire arms with single-shot or continuous fire, a catch arranged below the breech block has a nose which engages with the breech block, and can pivot as a result of friction-type connection with a trigger rod which can be moved by the trigger. An interrupter arm arranged on the trigger rod projects upward against the breech block. In the single-shot position, the upper end of said arm projects into the path of motion of a part of the breech block and is depressed by the breech block in order to release the friction-type connection between the trigger rod and the catch. In the continuous fire position, said end is thrust out of the path of motion of the breech block by an eccentric which acts on the trigger rod.</p> |
