Abstract: An ignition arrangement for a barrel weapon having a sliding wedge-type breech block in which a pressure bolt is rotatably mounted in the breech block and the firing pin is slidably movably mounted in the pressure bolt. The firing pin has a transverse rod which extends into a first pair of slots in the pressure bolt and a second pair of longitudinal slots in the breech block. The first pair of slots has a first transverse portion and a second helical portion. The pressure bolt is axially connected to a spiral spring biased control disc which has an actuating cam and a release cam. Coacting cam surfaces are adjustably mounted in the barrel weapon. The opening and closing movements of the breech block cause corresponding rotational movements of the pressure bolt due to the coactions of the actuating or release cams of the control disc with the coacting cam surfaces in the barrel weapon.
