Abstract
In present time, controlling of bolt motion in automatic weapons having blowback or blowback with delay executes by usage of mass of moving parts and its recoil spring power supported on frame. As result, all arising forces is transferred into frame and weapons have hard vibration and problems when executes shooting in automatic mode. Invention aimed at design of automatic weapons which executed more accurately automatically shooting and uses more powerful cartridges than conventional firearms of similar destination. Technical result achieved by supporting recoil spring on part that moves to shot direction under influence of powder gases. The feature of this method of controlling is that length of spring compressing is greater than stroke length of bolt. Vectors of inertia in claimed method are in antiphase and less then in conventional. As result, inertia of parts isn't transmitted to frame of firearms and reloading mechanism works into balanced manner.

There are a few fundamental disadvantages of these prototypes - they have or a high level of vibration of unbalanced parts both as the blowback operated weapons and as the delayed blowback operated weapons, or they have too complicated and unreliable the gear mechanism in the weapons which have a balanced, gas operated system.
The invention solves next problems - the creation of such method recharging of firearms and design of recharge mechanism on its basis in which, when powerful and special cartridges are used, the recoil and the vibration level is lower than in the prototype 1, 2.3 and 5,6 but the complexity of the mechanism there is less than in the prototype 4.
Claimed novelty differs from the prototype 1 so:
In claimed novelty, recoil spring of the bolt is supported on the mobile part (slider) that can move under action of powder gases.
In prototype 1, recoil spring is supported on the frame and powder gases only counteracts to movement of the bolt (slider).
In claimed novelty, the mobile part (slider) and bolt can move in opposite directions and carry out the self-balancing.
In prototype 1, the part that is under influence of powder gases is permanently coupled with bolt.
The claimed novelty differs from the prototype 2 so:
In claimed novelty, the bolt and the mobile part (slider) in first instant, before passing of the check point are moving together as regular blowback operated but after passing they move in opposite directions to each other and carry out the self-balancing.
In prototype 2, all parts of the recharging mechanism are moving in same direction only.
In prototype 2, recoil spring is supported onto frame and its unbalanced recoil force imparts to the frame of firearm.
The claimed novelty differs from the prototype 3 so:
In claimed novelty, the mobile part (slider) and bolt can move in opposite directions and carry out the self-balancing.
In claimed novelty, recoil spring of the bolt is supported on the mobile part (slider) that can move under action of powder gases.
In prototype 3, common parts of the recharging mechanism are moving in same direction only.
In prototype 3, recoil spring is supported onto frame and its unbalanced recoil force imparts to the frame of firearm.
The claimed novelty differs from the prototype 4 so:
In claimed novelty, the bolt and the mobile part (slider) in first instant, before passing of the check point are moving together but after passing they move in opposite directions to each other and carry out the self-balancing.
Firearm that based in the claimed novelty has a blowback or a delayed blowback operated breech system having recoil spring that is rested onto the movable part.
The prototype 4 has gas operated breech system with rotating bolt and recoil spring that rests onto frame.
The balanced breech system of prototype 4 is based on pinion drive.
Recoil spring is supported onto frame and it imparts some of recoil force to the frame of firearm.
As result of usage of both a pinion drive and as a rotating bolt the prototype 4 more complex to manufacture and more susceptible to fault due to pollution.
The claimed novelty differs from the prototype 5 so -This submachine-gun UMP 40 design as a modular firearm but, unlike of claimed in Claim 1-3, it has conventional recharging mechanism that is non-balanced.
The claimed novelty differs from the prototype 6 so ¨
In claimed novelty, the bolt and the mobile part in first instant, before passing of the check point (for barrel fig 33 or for movable part fig 32) arc moving together as regular blowback operated but after passing they move in opposite directions to each other and carry out the self-balancing.
In claimed novelty, recoil spring of the bolt is supported on the mobile part (slider) that can move under action of powder gases.
In prototype 6, after passing of barrel of the check point and, all parts of the recharging mechanism are moving in same direction only and they impart unbalanced recoil force to the frame of firearm.
Specified technical result is achieved by means of usage of the claimed above method of controlling of the parameters of motion of the lock, in which recoil spring of the lock is not supported on the frame of arms.
It is supported on the movable supportive platform 5 which is associated via the movable part 4 with the gas piston 3b or gas brake 3 and this gas piston or this gas brake can move in a shot direction under action of powder gases. Figl Fig 2 The recharging mechanism of the blowback operated firearm that acting in the manner described in Claim 1 includes: 1 ¨ barrel; 2 ¨ bolt; 3 ¨ gas brake; 4 ¨
slider; 5 ¨ supportive platform for recoil spring; 6 ¨ recoil spring; 7 ¨ aperture for gas bypass; 8 ¨ openings of gas brake; 9 ¨ bore of barrel; 10 ¨ dumper. Fig3 This recharging mechanism works in next manner At the initial moment of shot, bolt 2 under the influence of powder gases onto the cartridge case starts moving and compresses the recoil spring 6 relative to the supportive platform 5 that is connected with gas brake 10. After the start of the gas bypassing 11 through the aperture 7 into the gas brake 3 it moves toward under the action of propellant gas of shot and through slider 4 and platform 6 compresses the recoil spring 5 relative to the bolt 2. Fig4 In the final moment of shot, to the gases coming from the aperture 7 will be added the gases coming from the outlets of barrel and they, act onto the gas brake together, carry out transfer of this effort via the recoil spring into bolt 2. As result of that, the movement of the bolt 2 is slowed down and completely stopped, without any effort that can be transmitted to the frame of arms. Fig 5 A feature of such blowback is that the length L5 on which the spring 6 is compressed, is bigger than the stroke length L2 of the bolt. Fig6 This difference corresponds approximately to work of the lever-delayed blowback that is much more complex.
Comparing of the graphs shows that, at each time point, the vector of moment of inertia of the conventional bolt on graph P1 is greater than the vector of moment of inertia of the claimed bolt on graph P2 and the vectors of moments of inertia of weapon that work in the claimed manner are in antiphase during close time.

This blowback operated mechanism consists of two main parts - the bolt 2 and the locking block 16 that is inserted into it. The locking block has a hole through which the recoil spring 6 is installed. The locking block 16 has the rack 17 on the one side and the centering pivot 18 on the other hand.
The centering pivot and the rack get into the grooves on the slider 4 by influence of the spring 15 which is controlled by limiter 13 and adjuster 14.
The shock damper 10 has additional spring 12.
Recharge mechanism claimed in Claim 3 works as follows:
Before initial of the shot Fig 26, centering pivot 19 and rack 17 gets into the grooves on slider 4 by influence of spring 15. As result of that, bolt 2; locking block 16; supportive

The recharge mechanism that is claimed in Claim 3 is shown in Fig10, 11, 12, 13, 14, 15,16,17,18, 19, 20, 21, 22, 23,24, 25.
This blowback operated mechanism consists of two main parts - the bolt 2 and the locking block 16 that is inserted into it. The locking block has a hole through which the recoil spring 6 is installed. The locking block 16 has the rack 17 on the one side and the centering pivot 18 on the other hand.
The centering pivot and the rack get into the grooves on the slider 4 by influence of the spring 15 which is controlled by limiter 13 and adjuster 14.
The shock damper 10 has additional spring 12.
Recharge mechanism claimed in Claim 3 works as follows:
Before initial of the shot Fig 26, centering pivot 19 and rack 17 gets into the grooves on slider 4 by influence of spring 15. As result of that, bolt 2; locking block 16; supportive
7 platform 5; recoil spring 6; slider 4; gas brake 3 and coil 14 are united into mobile unit having a significantly higher total mass than the total mass of the bolt and of the locking block is.
In initial time of a shot Fig 27, under action of powder gases to a cartridge, this integrated module moves as blowback operated for which coil 12 of shock damper 10 works as recoil spring.
As this coil has high resistance to compression and the united module has enough big mass, this integrated module moves approximately only 2-3 mm to instant of any bypassing of gases via aperture 7. After that, coil 15 raises locking block 16 and unlocks all parts of united module under influence of adjuster 14.
After unlocking of parts of the united module, the recharging mechanism works in the manner declared in Claim 1. Fig 28.
Gas brake 3 under the influence of powder gases moves forward and supportive platform 5 will begin squeeze recoil spring 6 relative to the lock 2, counteracting its motion. The lock begins to move in the opposite direction relative to the all parts which associated with the gas brake and they do not interact with the spring of shock damper.
As result of that, moment of inertia of the moving parts is not transmitted to the frame of firearms and the recharging mechanism is working into balanced manner After completion of a shot and an extraction of a cartridge - Fig 29, the lock 2 and parts 3; 4; 5 begin to move in the opposite directions in relation to each other. At this moment the recharging mechanism works in a balanced manner as described above.
In the final moment of reloading Fig 30, spring 15 sliding on the ledge of adjuster 14 along segment H and pressed centering pivot 19 of the locking block at slider 4, carrying out additional braking. Such braking provides a soft impact of the lock to the barrel and a soft impact of the supportive platform at the damper spring.
Moments that have arisen during impacts are in opposite phase and take place in close periods of times.

Fig 27 Action of the two-stage blowback operated mechanism in initial instant of shot (up to instant of bypassing of gases).
In initial time of a shot Fig 27, under action of powder gases to a cartridge, this integrated module moves as blowback operated for which coil 12 of shock damper 10 works as recoil spring.
As this coil has high resistance to compression and the united module has enough big mass, this integrated module moves approximately only 2-3 mm to instant of any bypassing of gases via aperture 7. After that, coil 15 raises locking block 16 and unlocks all parts of united module under influence of adjuster 14.
After unlocking of parts of the united module, the recharging mechanism works in the manner declared in Claim 1. Fig 28.
Gas brake 3 under the influence of powder gases moves forward and supportive platform 5 will begin squeeze recoil spring 6 relative to the lock 2, counteracting its motion. The lock begins to move in the opposite direction relative to the all parts which associated with the gas brake and they do not interact with the spring of shock damper.
As result of that, moment of inertia of the moving parts is not transmitted to the frame of firearms and the recharging mechanism is working into balanced manner After completion of a shot and an extraction of a cartridge - Fig 29, the lock 2 and parts 3; 4; 5 begin to move in the opposite directions in relation to each other. At this moment the recharging mechanism works in a balanced manner as described above.
In the final moment of reloading Fig 30, spring 15 sliding on the ledge of adjuster 14 along segment H and pressed centering pivot 19 of the locking block at slider 4, carrying out additional braking. Such braking provides a soft impact of the lock to the barrel and a soft impact of the supportive platform at the damper spring.
Moments that have arisen during impacts are in opposite phase and take place in close periods of times.
