Abstract

FIELD: weapons.

SUBSTANCE: invention relates to small arms and represents an automatic gun that comprises barrel, breech box with bolt, hammer with spring, trigger with spring, automatic fire sear with spring, single fire sear with spring, firing lever with spring, shots counter with spring and safety lock and four-position fire selector: "safe", "single fire", "limited burst" and "burst". In "single fire", fire selector moves trigger lever and automatic fire sear out of engagement with firing lever, breech frame and trigger. Single fire sear stays in contact with trigger, breech frame and cock. Note here that shots counter is set into position whereat one of its ledges stays in contact with single fire sear. All ledges of shots counter stay in contact with single fire sear when in "limited burst" position. In "automatic fire" position, fire selector moves single fire sear and shots counter out of contact with cock, trigger and breech frame, while trigger lever interacts with breech frame in its counter recoiling between locking the bolt and coming into breech frame extreme front position, with single fire sear after breech frame comes into extreme front position and with cock after it comes off the sear.

EFFECT: higher efficiency of fire.

Description

The invention relates to the field of weapons technology, in particular to machine guns.

The known design of the trigger mechanism of the AK-74 assault rifle with a moderator trigger / Popenker M.R. Assault rifles of the world. Moscow, LLC "Publishing house ACT", 2004, pp. 144-165 /. The disadvantage of this design is the insufficient degree of lowering the rate of fire and the inability to turn off the moderator, which makes it impossible to use a similar mechanism in machines with a variable rate of fire.

Known design of the Nikonov assault rifle AN-94 with a recoil impulse accumulation system / Popenker M.R. Assault rifles of the world. Moscow, LLC "Publishing house ACT", 2004, pp. 144-165 /. A similar principle makes it possible to adjust the rate of fire in a wide range, however, the disadvantages of this machine are its great complexity, size and weight.

The objective of the invention is to create a simple light machine with the ability to change the rate of fire in a proportion of not less than 1: 3 thanks to the use of a deactivable retarder, the main part of which is a spring-loaded trigger lever, sequentially acting as a retarder of the bolt frame when it is rolling, a retarder of the operation of the whisper and a retarder of the trigger . This solution allows for a significant decrease in the rate of fire without unnecessarily complicating the design of the weapon and without reducing its reliability.

The essence of the invention consists in creating an automatic weapon consisting of a barrel, a receiver, a bolt frame with a bolt, a trigger with a combat spring, a trigger with a spring, whispering automatic fire with a spring, whispering a single fire with a spring, a trigger lever with a spring, counter shots with spring, translator fuse, having four positions - "on the fuse", "single fire", "limited turn", "automatic fire" and characterized in that when the position of the translator fuse is "single fire "its sector disengages the trigger and automatically fires the trigger with the trigger, bolt and trigger, the single-fire whisper has the possibility of contact with the trigger, bolt and trigger, while the shot counter is set to a position in which only one of its protrusions has the possibility of contact with the sear of a single fire, with the position of the translator-fuse "limited queue" the position of the parts is the same, except that all the protrusions of the shot counter are possible contact with the single-fire sear, when the automatic fire switch is in the fuse-translator sector, the translator-safety sector disables the single-fire sear and the counter of shots from engagement with the trigger, trigger and bolt frame, and the trigger lever can interact with the bolt frame when it is rolling in the period between locking the shutter and the frame comes to the extreme front position, it also has the ability to interact with the sear of a single fire after the bolt frame comes to the extreme front floor the increase and the possibility of interacting with the trigger after its breakdown from a whisper.

The invention consists of a barrel / 1 /, a receiver / 2 /, a bolt frame with a shutter / 3 /, a return spring / 4 /, a trigger / 5 /, a trigger spring / 6 /, a single fire whispered / 7 /, a sear single fire / 8 /, counter of shots / 9 /, springs of the counter of shots / 10 /, whispered automatic fire / 11 /, springs whispered automatic fire / 12 /, trigger / 13 /, spring trigger / 14 /, trigger / 15 / , trigger spring / 16 /, translator-fuse / 17 /. The shot counter / 9 / has projections / 18 / for contact with a single-fire sear and protrusions / 25 / for contact with the bolt frame / 3 /, the trigger lever / 15 / has projections / 19 /, / 20 /, / 21 / for interaction with bolt frame / 3 /, automatic fire sear / 11 / and trigger / 13 /. The fuse translator has a sector / 22 /, which, depending on the position of the fuse translator / 17 /, has the ability to contact the trigger lever / 15 /, the automatic fire sear / 11 /, the single-fire sear / 7 / and the shot counter / 9 /. The bolt frame / 3 / has projections / 23 / and / 24 / for interacting with the trigger lever / 15 / and the shot counter / 9 /.

When the translator-fuse / 17 / is in the position for firing at a normal pace, its sector / 22 / displays the shot counter / 9 / and whispers a single fire / 7 / out of contact with the trigger / 13 /. The trigger lever / 15 / has the ability to contact the trigger, the automatic fire sear / 11 / and the bolt frame / 3 /. After the first shot, the bolt frame / 3 / moves back, removing the spent sleeve and putting the trigger / 13 / on the sear of the automatic fire / 11 /. After reaching its extreme rear position, the bolt frame under the action of the return spring / 4 / starts moving forward and, after grabbing the next cartridge from the magazine, comes into contact with the protrusion / 19 / trigger lever / 15 /, moving it back and compressing its spring / 16 /, in the future, after locking the bolt, the bolt frame / 3 / disengages with the trigger lever / 15 /, which, under the action of its spring / 16 /, moves forward and with its protrusion / 20 / interacts with the automatic fire sear / 11 /, pressing it down and releasing lesson / 13 /, who in the course of its forward motion interacts with the protrusion / 21 / sear / 15 / squeezing with its spring / 16 / and tripped him before his attack on the drummer. Thus, the process of slowing down the rate of fire consists of three stages - slowing down the shutter frame, slowing the trigger down from the sear and slowing the trigger itself.

When the translator-fuse / 17 / is in the firing position, the sector / 22 / disengages the trigger lever / 15 / and whispers automatic fire / 11 / out of contact with the trigger / 5 /, the shutter frame / 3 / and the trigger / 13 /, and the shot counter / 9 / and the whisper of a single fire / 7 / get the opportunity to contact the trigger / 13 /, the trigger / 5 / and the bolt frame / 3 /. After pulling the trigger / 5 / he squeezes down the sear of a single fire / 7 /, releasing the trigger / 13 / and allowing the counter of shots / 9 / to move under the action of its spring / 10 / by one division. Subsequently, when the shutter frame / 3 / is rolled over, it acts on the protrusions / 25 / of the shot counter / 9 / with its protrusion / 24 /, releasing the trigger / 13 / again and allowing the shot counter / 9 / to move one division, compressing the spring / 10 / . After the shot counter / 9 / moves to the maximum number of divisions on it, it comes out of contact with the bolt frame / 3 /, which will lead to automatic interruption of firing. The return of the counter of shots / 9 / and the whisper of a single fire / 7 / to its original position is carried out when the trigger is released / 5 / under the action of the spring / 10 /.
