Description

The invention relates to firearms: submachine gun, PDW (Google - PDW weapon), "automatic", carbine, rifle, machine gun, grenade launcher, cannon, etc. The Power System (SP) consists of a barrel, a bolt, a bolt spring, a return spring, a damper spring, a damper piston, a damper cylinder, a rod with a nut, a copier-rammer, lodgements, a barrel guide, a pin, a pipe-handle, an axle-tube. The objective of the invention is to create a joint venture for a weapon with a forward stroke, providing the technical result: maximum reliability of feeding an absolutely whole cartridge into an absolutely whole barrel chamber, without sticking, wedge, etc. etc. and along the way, a simple and reliable ejection of cartridge cases down, without an ejector, without a reflector, it is comfortable and safe, both for the fighter and for others, it is possible to conveniently and safely shoot, both on the right and on the left, with minimal recoil, dimensions and weight of the weapon and the highest accuracy and accuracy of all types of fire.

There is one more variant of the joint venture out of several, as an option for PDW with a domestic reinforced cartridge 9 × 21 and, moreover, with the most powerful gunpowder. Take for example a PDW with a barrel length of 254 mm (10") (barrel length can be taken 100 mm - 600 mm). The length of the weapon will be, for example, 350 mm, about 340 mm when cocked, (you can take 200 mm - 800 mm) and for example, with a retractable butt, etc. - you get a PDW, approximately 450 mm long when deployed, about 440 mm when cocked (you can take a length of 200 mm - 900 mm). forward is described in patent 2717112 "Firearms with a barrel stroke forward", as well as in patent 2697184. Here, as an option, only the joint venture is changed and, as an option, the spring block (separate patents) is removed away from the hot barrel and a balanced system (SS) is added (separate patents).

Disclosure of invention

Follower Radius 44 FIG. 1 we take for example 8 mm, the radius of the rammer is 45 fig. 1 for example 24 mm, this means the amplitude of the stroke "p" of the current copier 44 FIG. 2 will be 3 times less than the stroke amplitude P FIG. 2. theoretical copier 63 FIG. 2 with the same result of the stroke of the rammer 45 of FIG. 1 and the ratio of the short radius, with respect to the long radius can be 1:1÷1:10, this gives the compactness of the copier 44 FIG. 2. Let's trace one cycle of weapon automation, starting from the position in Fig. 1. Before this, after the shot, the barrel 1 of FIG. 7 engaged with the closure 39 of FIG. 7 goes forward (see the above patents), pin 51 of FIG. 1 also, after the pin 51 is in the position in FIG. 2. Further, when the barrel moves forward, the pin 51 of FIG. 2 travels the path H of FIG. 2 and cartridge 57 of FIG. 1 under the action of the rammer 45 of FIG. 1 moves along the radial guides 62 of FIG. 1 on the shutter (the shutter is conventionally not shown) on the axis of the bore 1 FIG. 1, the rammer in this position is shown in dashed lines in FIG. 1 and during this stroke the rammer arc 45a of FIG. 1 locks the cartridge 58 of FIG. 1 in store 59 FIG. 1., also at this time the spent cartridge case 56 of Fig. 1 under the action of the advancing cartridge 57 of FIG. 1 along the straight section of the guide sleeves 55 of FIG. 1 will move to the left and rest against the barrel guide 54 of FIG. 1 (the barrel guide 54 of FIG. 1 can be placed anywhere along the wide arc of the barrel 1 of FIG. 1, shown in phantom lines), the advanced cartridge 57 of FIG. 1 abuts against the advanced sleeve 56 of FIG. 1 and will stand exactly on the axis of the bore 1 of Fig. 1. and further, during the reverse stroke of the barrel 1, the incoming cartridge 57 of Fig. 1 will fall into the chamber without the slightest damage to the cartridge and chamber. In this case, the stroke of the cartridge 57 of Fig. 1 on the axis of the bore begins smoothly, with increasing speed, without a sharp initial bolt strike, like in the classics, this sharp start has an extremely negative effect on the cartridge, as well as a sharp stop of the classics. Next, the pin 51 of FIG. 2 enters segment B of FIG. 2 and rammer 45 of FIG. 1 (shown in dashed lines) stands still, in the leftmost position, while the stem 1 of FIG. 7 compressing 2 springs: return spring 78 FIG. 7+buffer spring 76 FIG. 7 nut 79 FIG. 7 on the right and moving the counterweight cylinder 71 of FIG. 7 back, with projection 74 of FIG. 7, further barrel 1 Fig. 7 hits the checkpoint with FIG. 2 (in brackets in Fig. 7 is shown conventionally), at this moment the counterweight cylinder 71 of Fig. 7 synchronously strikes back at the CFC of FIG. 7, compensating for the blow of the barrel forward. Next, the trunk 1 Fig. 7 stops for a moment and walks back. Then the finger 51 of FIG. 2 returns to section O of FIG. 2 -- trunk 1 Fig. 1 comes into position in FIG. 1, only there is no cartridge 57 FIG. 1, and the rim 45b Fig. 1 continues to lock the cartridge 58 of FIG. 1 in store 59 FIG. 1 but cartridge 58 of FIG. 1 at the same time advances forward and rests against the rim 45b of FIG. 1 (cartridge shown in dashed lines). Next, the pin 51 of FIG. 2 passes section D and the rammer 45 of FIG. 1 goes a little more to the right (1÷10 mm), in this case about 2 mm and the lip 45b Fig. 1 goes beyond the cradles 48 of FIG. 1, opening the way for the incoming cartridge 58 of FIG. 1, at this point the stem 1 of FIG. 1 comes under the incoming cartridge 58 of FIG. 1 (shown in dashed lines) 50% ÷ 100% of cartridge case length 58 FIG. 1, in this case, about 70% and the cartridge 58 of Fig. 1, leaning on the stem 1 of FIG. 1 securely enters and rests on the cradles 48 of FIG. 1. Lodgements 48 FIG. 1, at the point of contact with the cartridge are made a little freer and the cartridge resting on the rise of the end of the lodgements 48 Fig. 1 will move away from the stem 1 of FIG. 1 by fractions of a mm (0.1÷5 mm) Here 2 goals are achieved: 1 - the cartridge will not touch the red-hot barrel 1 Fig. one; 2 - cartridge, preloaded by the magazine spring 59 FIG. 1 will be clearly fixed in the cradles 48 of FIG. 1 until the rammer 45 of FIG. 1 will NOT start working. Next, the trunk 1 Fig. 4 will engage the bolt 39 of FIG. 4 = IF (there are options for coupling the barrel with a bolt with transverse wedges - separate patents), then the IF go back, while the round part of the stem. 49 Fig. 8 (shown in dashed lines) abuts against the piston 75 of FIG. 7 and will move it to the right, compressing the damper spring 76 of FIG. 7 on the left, also with shutter 39 of FIG. 7, the inverters will compress the spring 82 of FIG. 7 and again the inverters lose speed when counterbalance cylinder 71 of FIG. 7 upon impact with projection 73 of FIG. 7 into lever 72 of FIG. 7, next comes the impact of the counterweight cylinder 71 of FIG. 7 in KPPts, which synchronously compensates for the impact of the inverter in (KZPch) - in brackets it is conditionally shown in Fig. 7. Here, the mass of the counterweight cylinder is half the mass of the counterweight of the AEK-971 (Google weapon AEK-971), etc., everything depends on the ratio of the short arm to the long arm 72 FIG. 7 (1:1÷1:10), pin 51 FIG. 2 also goes to KZPch on segments F + Z. In KZPCH, the inverters stop for a moment and go forward and on segment 3 of Fig. 2 a shot is fired (there are different versions of the USM - separate patents), again a coupled system (IF) - barrel 1 Fig. 7 + shutter 39 FIG. 7 stops for a short time, then the gas engine 13 of FIG. 7 (gas engine under the barrel, which reduces the rise of the barrel and the dimensions of the weapon) and the barrel 1 of FIG. 7 goes ahead. On the border of plots 3 and Zh on M.T. Fig. 5, the shutter 39 stops, the barrel 1 goes further forward by inertia. Coming from the store 59 of FIG. 1 cartridge 58 fig. 1 during this time manages to stand on the lodgements 48 of FIG. 1. Next, the pin 51 of FIG. 2 passes section e, the rammer 45 of FIG. 1 goes to the left, for example by 2 mm, then the pin 51 goes forward along the section O of FIG. 2 and comes to position 51 of FIG. 2 - the cycle is closed and again we have the form as in Fig. 1. Here the copier-mailer is 44+45 FIG. 1 (key part) performs 4 functions: 1 - advances the cartridge 57 in the shortest and "non-traumatic" way. FIG. 1 on the axis of the bore 1 FIG. one; 2 - advances sleeve 56 of FIG. 1 to guide 54 of FIG. 1 - the first stage of ejection of the sleeve outside the weapon (guide 54 Fig. 1 also performs 2 roles: 1 - is a guide for the barrel 1 Fig. 1; 2 - is a transshipment nest for the sleeve, before ejecting it outward); 3 - holds the cartridge 58 of FIG. 1 in store 59 FIG. 1 until needed. 4 - there is actually a copier. As a result, we have an absolutely whole cartridge in an absolutely whole chamber, because the cartridge moves perpendicular to the axis of the cartridge and is "traumatic" It does NOT touch anything on the way to the chamber, unlike the classics. Here, any cartridges are fed WITHOUT jamming, WITHOUT damage, etc. etc., including with any complex heads. Hexagonal portion 51a of FIG. 1 finger 51 FIG. 1, at the point of contact with the shaft 1 of FIG. 1, made with radial "Yeshi Grooves", such as "Revelli Grooves" (Googte - Revelli grooves), for example, 6 pcs. the finger can be easily unscrewed, if not, we cut off the finger and cut a repair thread, a slightly larger diameter - this is similar to the repair, piston rings of an internal combustion engine - an internal combustion engine, as an option, the finger can be made in one piece with the barrel. there is no bolt rammer in the joint venture (with this rammer you can jam the weapon in such a way that it can render the weapon unusable), there are no small parts and springs, unlike the classics, where these small parts and springs (ejector, reflector) work in difficult conditions and are practically impossible to repair in the field. pdw has the shape of a curved flask and will be unnoticeable under a jacket, etc. Having picked up a combination: cartridge, barrel length and weapon length, you can put three magazines and then, as an option, we will have 75 rounds of ammunition on one charge of the weapon, with a reliable supply of cartridges in each individual magazine, with a continuous supply of full magazines, as they are emptied and discarding empty magazines, and out of combat you can comfortably carry weapons with 1 magazine (all this is the same with 2 magazines, see the above patents, as well as with 4 or more), unlike any automatic weapon with a capacious magazine. There is an option: install a spring block in the left, empty corner of the weapon Fig. and sliding the spring block towards the barrel cut, then we will have an even shorter weapon, for example, 320 mm when folded, with a 10 "barrel, and the balance of the weapon will be better. Almost ALL parts of the joint venture perform two or more functions, including cylinder-counterweight 71 Fig. 7. Buffer spring 76 Fig. 7 performs 4 functions: 1 - softens the blow of the barrel forward, the sound of the blow also decreases; 2 - softens the blow of the IF back, the sound of the blow also decreases; 3 - partially fulfills the role mainspring for USM (Trigger Mechanism); 4 - partially acts as a return spring. The barrel is multifunctional: 1 - shot; 2 - moves the cartridge from the magazine to the barrel; 3 - reliably, comfortably and safely ejects the cartridge case down outside the weapon; 4 - actuates the SS; 5 - due to the "fan effect" the barrel, with the appropriate relief, cools better (separate patents); 6 - creates a trigger WITHOUT long and inertial thrust - an extremely unsuccessful part of the bullpup classic (separate patents); 7 - activates the Mechanism of the catcher of long shots (separate patents); 8 - initiates mitigation of barrel blows, both forward and backward, also compensates for blows in the gearbox and in the KZPch (separate patents). To simplify for PDW and submachine guns, the SS can be removed, but with long and heavy barrels, the SS is necessary, as an option, you can leave only a part when the barrel hits forward. There is a simple and reliable store for new weapons (separate, related patents). It is possible to make a weapon without a rod-cylinder and perform all manipulations with the barrel with the cocking handle 84 Fig. 7, you can also safely lower it from the platoon, with a cartridge in the chamber and you can put it on the platoon by poking the barrel into a tree, etc., and make the SS with a separate counterweight part (separate patents). Due to the low recoil, DTK is not needed ( Muzzle Brake-Compensator), with all its disadvantages.

Essential features of the invention:

- we have the shortest and completely "non-traumatic" movement of cartridges from the magazine to the chamber - the movement of cartridges goes across the weapon, unlike the classics, with all its disadvantages.

- we have shots on the roll-out of massive firearms, which significantly reduces the recoil of the weapon, the recoil of the weapon also decreases when the barrel counter-moves to the main mass of the weapon.

- the shutter is compact, much simpler, more technologically advanced, lighter and has a very short stroke when firing - this is the compactness of the weapon and there will be no loud clatter of the shutter when firing with a silencer, like the classics.

- The joint venture is original, reliable, compact, silent, cheap, and there is no huge list of classic shortcomings.

- with such a joint venture, the weapon is completely closed and sand, dirt, etc. they will not get into the mechanisms of weapons, including when firing, when firing, smoke does not fly directly into the face, it is possible to shoot comfortably and safely, both on the left and on the right, neighbors will not be injured by flying cartridges, and the fighter will not be injured during prolonged shots.

- at the same time, the joint venture softens the blows of the barrel forward, without a loud knock and the IF back, without a loud knock.

-- with the proposed SP, the USM can be cocked for a very long time without much harm to the weapon.

-- the rate of fire can be adjusted, the farther the gas outlet from the treasury, the lower the rate of fire (separate patents).

- do not need complex, expensive and unreliable: ejector, reflector, DTK and shutter rammer like the M-16 (Google - M-16 weapon).

- the weapon can be silently and safely lowered from the platoon with a cartridge in the chamber, and you can cock it by poking the barrel into a wall, tree, etc. and it will be fast and silent (separate patents), it will also be fast and silent with the usual cocking of this weapon, which is not the case with all firearms in the world.

-- gas engine under the barrel, while reducing the toss of the barrel and the height of the weapon.

-- no heavy and inertial thrust USM.
