Breech device with integrated linearly movable firing pin pulse generator

A breech device (100) of a firearm comprising:

• a breech body (110) with a lower part with functional elements for interaction with an upper region of a handle part of the firearm;
• wherein:
• a firing pin (130) is linearly movable within a bore (120) of the breech body (110) with a leading end face (111) adjacent to the cartridge chamber (200) of a barrel (210) of the firearm from a retracted basic position into an advanced firing position, in which an ignition pin (138) of the firing pin (130) strikes an ignition element of a cartridge (300) to fire a shot;
• the firing pin can be propelled by means of a pulse generator (140) which is also linearly movable within the bore;
• the firing pin (130) comprises a firing pin head (131) and a firing pin body (132);
• the firing pin head (131) is mounted linearly movably within the bore (120) in a region of the breech body (110) close to the barrel;
• the firing pin body (132) is mounted linearly movably along an inner surface (151) of a sliding guide (150) also arranged in the bore (120);
• and
• the pulse generator (140) is linearly movable along an outer surface (152) of the sliding guide (150).
