Abstract
An operating system for an individual firearm, such as a rifle, comprises a carriage (14) sliding axially in the compartment of the body of the firearm, an obturator (10) associable to the barrel (2), an elastic element (16), compressible between the carriage (14) and the obturator (10). In the configuration of firearm ready to fire with the bullet in the barrel, the obturator (10) has a free compression stroke (D) for the compression of the elastic element (16) and the barrel (2) has a free firing stroke (C) in relation to the abutment (32) of the operating compartment (8).
Claims11
An individual firearm, comprising:
- a body containing an operating compartment, having an abutment;
- a barrel extending mainly along a barrel axis, between a free distal end for the exit of the firing forces of the cartridges, and an opposite proximal end, containing a cartridge chamber, engaged with the body, said barrel sliding axially in relation to said body;
- an automatic operating system for performing a cycle of opening, extracting the case of a fired cartridge and loading a new cartridge following the firing of the previous one, comprising:
- a) a carriage, housed in the operating compartment of the body, sliding axially in said compartment;
- b) an obturator associable with the proximal end of the barrel in a releasable manner, suitable to close the cartridge chamber;
- c) an elastic element, compressible between the carriage and the obturator;
- wherein in the configuration of the firearm when ready to fire with the bullet in the barrel, the obturator has a free compression stroke for the compression of the elastic element and the barrel has a free firing stroke between a limit forward position and the abutment of the operating compartment, wherein the free compression stroke is less than the free firing stroke;
- the firearm characterized by the fact that the elastic element comprises a plurality of Belleville springs.
