Description

The invention relates to weapons, in particular to the limiters of the number of shots, and can be used in individual small arms of the “gun-mounted machine” class to limit the number of shots in the production of a “fixed” line.

Known limiter of the number of shots / Babak F.K. “Basics of small arms”, Polygon Publishing House, 2003, pp. 179-180, see the description of the limiter on the number of shots for a machine gun WZ-88 /, which prevents impact on the hammer of a trigger machine after firing a specified number of shots in a “fixed” Queues of weapons.

The disadvantage of this device is its complicated design, unsuitable for small arms of the “carriage automaton” class, which has an additional “intermediate” magazine with its own lever feeder for cartridges, which ensures the production of a “fixed” line when the “firing unit” of weapons is rolled back.

Known limiter of the number of shots / see Patent for invention No. 2393404, author-applicant Glukhov A.V., Russia /, which is the closest analogue in technical essence to the claimed object, because, being an earlier development of the author and this application, carried out as part of one project automatic machine ”, it contains a breech“ locking ”protrusion of the lever cartridge feeder for the“ intermediate ”magazine, located on the side wall of the receiver of the“ firing unit ”, with the possibility of the passage of the“ locking protrusion ”through the hole of this“ wall ” when emptying the “intermediate” store, for locking in the inaccessible position to the chamber with the remaining cartridge, the bolt frame of the weapon having an appropriate side cutout, and with the possibility of automatic shutdown of this “limiter” at the end of the rollback of the “firing unit” of the weapon due to the impact on the breech lever feeder cartridges, "diverting" protrusion placed inside the "bed" of this weapon, for disengaging the bolt frame with the protrusion of the feeder.

The disadvantage of this device is the placement of the said lever “cartridge feed” on a vertical hinge, as well as the implementation in the form of a hole in the side wall of the receiver of the element providing passage to the bolt frame of the weapon, the said breech “coupling protrusion” of this “cartridge feeder”, which does not allow use this device on a “gun machine” equipped with a vertical box-shaped “intermediate” magazine.

The technical task is to adapt the mechanism of the automatic limiter of the number of shots for the “gun-mounted assault rifle”, which has a box-shaped “intermediate” magazine with a lever “cartridge feed” vertically placed on the “firing unit”.

The technical result is achieved by the fact that the limiter of the number of shots is placed on the individual small arms of the “gun-mounted machine” class, equipped with an additional “intermediate” box-shaped magazine of small capacity, permanently placed on the side wall of the receiver of the “firing unit” above the lower “main” store and equipped with its own spring-loaded lever “cartridge feeder” having a breech “coupling protrusion” facing the bolt frame and placed during operation of this “restriction caliper ”in the side hole of the receiver’s wall of the“ firing unit ”with the possibility of engagement with the“ lateral stop of the slide frame ”in the“ non-profit ”position of the latter to the chamber with the last loaded cartridge from the“ intermediate ”magazine, and there is a breech-fed“ ledge ”protector of the cartridge to automatically turn off the mechanism of this “limiter” when completing the rollback of the “firing unit” due to the interaction of this “diverted” protrusion with another placed on the fixed part of the weapon with a “protruding protrusion”, also provided that the “disconnector” mechanism for the bolt frame and hammer has been previously activated, in addition, the said wedge-shaped “protruding protrusion” is placed on the inner surface of the “breech wall” of the side longitudinal “pocket” - the “guiding bed” of the weapon, which serves to the passage of the “intermediate” store and its lever “cartridge feed”, and the existing wedge-shaped “outlet” protrusion is placed in the breech of this “pocket” with the possibility of impact when the “shooting ag egata "to" withdrawn "projection of said lever" feeder cartridges "diverting last up to a value smaller than the diameter of the sleeve used cartridge, sufficient to disengage the bolt from" the composite "protrusion lever" feeder cartridges "of said" intermediate "store.

Distinctive features in the claimed combination show a new property - the ability to place elements that make up the mechanism of the “limiter of the number of shots: the“ engaging ”and“ retracted ”protrusions in the breech of the spring-loaded lever“ cartridge feed ”for the box-shaped“ firing unit ”box “Intermediate” magazine, which has a small capacity, while the said “cartridge feeder” for this magazine is placed on a horizontal muzzle re, and its mentioned “engaging” protrusion is placed in the vertical “sector” slot available on the side wall of the receiver of the “firing unit”, also with the possibility of the passage of this “engaging” protrusion - when emptying the “intermediate” store, into the corresponding stop cutout ” available on the lateral longitudinal rib of the slide frame of this gun weapon.

The technical result is ensured by the fact that the on and off of this “limiter of the number of shots” is fully automated and is carried out both depending on the degree of emptying of the “intermediate” vertical magazine, and the position of the “firing unit” of weapons being rolled back inside the “guide bed”.

The invention is illustrated by drawings, where figure 1 shows the mechanism of the "limiter of the number of shots" in a "fixed" queue, side view, left; figure 2 shows a horizontal section aa / s figure 1 /.

The limiter of the number of shots comprises a “breech clutch protrusion” 2 having a reinforcing chrome coating 3 and a “breech retracted protrusion” 4 interacting with a “wedge-shaped divert element” 5 having muzzle bevel 6, rigidly connected to the “breech wall” 7 of the lateral longitudinal pocket 8 on the “guide bed” 9 of the weapon having the upper longitudinal cover 10. Also shown are the receiver 11 with a lateral sector slot 12 for the protrusion / 2 /, side box-shaped “intermediate “shop” 13, lateral horizontal hinge 14 of the lever “cartridge feeder” / 1 / having a return spring / torsion / 15; chamber 16; rotary shutter 17; drummer 18, its “return spring" 9; the bolt frame 20 and its “lateral longitudinal rib” 21 with a “persistent notch” 22; node "disconnector" / bolt frame with drummer / 23; lower box-shaped “main” store 24; cartridges 25 of this weapon.
