摘要:
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).

An obturator (100) for firearms comprises: a structure (101); a closing head (102), in particular a rotary one, arranged at an end (103) of the cylindrical structure (101); at least a resting surface (104) defined on the closing head (102) to engage the bottom (F) of at least one cartridge (C); at least one through channel (105) extending longitudinally through the cylindrical structure (101) for operatively engaging at least one striker of the firearm. The obturator comprises deformation means (108) associated with the closing head (102) to at least partially deform a firing capsule (109) and/or a bottom of a cartridge (C) loaded on the firearm.
摘要:
A locking and recocking assembly with swivel breech-lock and rotating locking head particularly designed for inertially-actuated weapons, which combines in a single assembly all the functions for locking, opening, case ejection and recocking with locking return, required for correct operation of the weapon; those functions were, until now assigned to various components variously assembled on the weapon. The locking and recocking assembly with swivel breech-lock and rotating locking head has the entire mass, required for inertial operation, concentrated in the swivel breech-lock, which is accommodated completely within the supporting structure of the weapon, such as the sheath or barrel extension or breech of the weapon. All this leads to better balancing and stability of the weapon, higher reliability in operation, greater constructive simplicity and ease of assembly and disassembly.

The invention relates to an arrangement of locking projections (21) at the locking head (19) of a locked self-loading hand gun. The locking head (19) can be mounted in two different ways, whereby the cartridge extractor (23) is arranged horizontally to the left or right. A locking projection (21) is omitted at the place of the cartridge extractor (23) so that an uneven number of locking projections (21) is provided. The locking projections (21) are arranged in such a way that they extend along both sides of the lips (27) of a given magazine when the lock (3) is released instead of being distributed over the circumference of the locking head (19) with the same angular distance.

Bei einem Gehäuse eines Selbstlade-Granatwerfers ist der Masseverschluß (202) von mindestens einem Längskanal durchsetzt, der mit Spielpassung auf einer im Gehäuse (102) ortsfest angebrachten Längsführung (132) verschieblich geführt ist.
摘要:
The invention relates to a device and a method for loading a cartridge (3) into a battery (2) of a barrel (1) of an autoloading firearm. Said device comprises a bolt (8) which is able to slide in the longitudinal direction of the firearm and serves to move the cartridge (3) and to introduce said cartridge (3) into the battery (2). The invention provides for at least one centering element (5b) which is irremovably fixed to the barrel (1) and serves to center the bolt (8) in relation to said barrel (1).
