Description

 The invention relates to a gas-gas weapon, to a group of carbon dioxide gas balloon weapons, in which compressed carbon dioxide vapors enclosed in standard gas cylinders are used as a working fluid.

 Carbon dioxide gas weapons, in the form of pistols and revolvers, are produced in large quantities abroad. At the same time, one of the basic requirements for samples of such weapons is the fullest possible repetition of the external dimensions and shape of firearms and revolvers. The closest to the device to the proposed multiply charged gas balloon revolver is the American firm CROSMAN revolver [1] repeating the external contours and dimensions of the PITON 357 combat revolver [2] The carbon dioxide gas cylinder revolver from CROSMAN was selected as a prototype model of the proposed device. As a sample, the external contours and dimensions of which are repeated by the proposed multi-charged gas balloon revolver, the Nagana revolver arr. 1895 produced for decades in Russia [3] Revolver Nagana arr. 1895 is hereinafter referred to as the original sample.

 The main features of the prototype sample are: the location in the handle of a gas cylinder pressed against the needle valve by a pressure screw; the presence of two needle valves, opening access to compressed carbon dioxide, and a worker connected by a tube; a narrow, about 8 mm thick drum, equipped with six or ten special bullets of caliber 4.5, equipped with a special obturating "skirt". The equipment of such a store after every six (or ten) shots takes a lot of time, no less than a combat revolver with live ammunition. In order to use up one standard carbon dioxide cylinder, you need to reload the drum 6-10 times. Unreliable and obturation of such a plate drum, because both cavities must be shuttered, which leads to unjustified loss of energy of the compressed gas. In addition, when shooting, only a narrow plate drum rotates, and the rest of it only simulates the shape of the drum of the original sample. The plate drum is placed directly in front of the barrel. So to accelerate the bullet used barrel length corresponding to the length of the original sample. The gas cylinder preloading system, although generally accepted, is also characterized by the disadvantage of a low cylinder preload speed due to the low speed of movement of the screw in the screw pair. This causes unproductive carbon dioxide bleeding for several seconds even before firing when preloading the balloon. A device that returns the valve stem to its original position when the trigger is pulled in the prototype sample contains a long rod associated with the trigger. The cylindrical rod at the end of the thrust at the time of the shot is placed between the trigger and the stem of the working valve and the impact from the trigger to the rod is transmitted through it. Immediately after the shot, the cylindrical rod lowers and the rod returns to its original position without opposition from the mainspring. The device allows to reduce the opening time of the working valve and plays the role of a mechanism from the trigger of a trigger in military weapons in gas-balloon weapons. Its main disadvantage is complexity, relatively large dimensions and insufficient reliability. In addition to the above disadvantages, it should be noted that the use of bullets with an obturating "skirt" makes it difficult to automate any operations. In this sense, unpretentious from the point of view of storage and operation, ball bullets having better ballistic characteristics are more convenient.

 The technical result of the present invention is to improve the operational characteristics of gas balloon revolvers, increasing ammunition while more fully reproducing the shape and size of the original sample. The technical result is achieved by the fact that in a multiply charged gas cylinder revolver containing a housing, a cover, a movable and fixed part of the drum with an axis, a barrel, a tube, a gas cylinder located in the handle, needle and working valves, a connecting tube, a mechanism for rotating the movable part of the drum, the trigger with auto-trigger, trigger, single sear and fuse, the movable part of the drum is made in the form of a cylindrical cage containing longitudinal channels with feeders and feed springs for equipment ball round bullets and a circular groove on the end surface, and a profiled protrusion made in the circular groove of the holder to reduce bullets in the tube is made on the body. In addition, in a multicharged gas balloon revolver, the tube is made elongated to the rear end surface of the drum and passes through its fixed part, is equipped with a shutter in the form of a spring-loaded cylindrical ring with a protrusion, and a figured groove is made on the inner surface of the holder for interaction with the protrusion of the shutter. The supply of bullets in this way is carried out in the region of the rear end of the drum, which significantly lengthens the barrel. So, if in the prototype sample the barrel length is 100 or 150 mm [2] with a total revolver length of 230 or 280 mm, respectively, then in the proposed sample the barrel length is 150 mm with a weapon length of 230 mm. The specified technical result allows to exclude the obturation on two planes and limit one, while making it more reliable.

 In addition, ledges are made in the revolver on the inner surface of the cage, and the rotation mechanism is located inside the fixed part of the drum and contains a slider with an inclined groove moving longitudinally as a result of interaction with the trigger, a return spring and a two-arm lever with one shoulder for interacting with the inclined slider groove and the second, equipped with a spring-loaded latch for interaction with the ledges of the clip. In this case, the revolver is equipped with a clamping cover located in the lower part of the handle containing the axis, a screw with a cup and a latch, and a spring-loaded lock is made on the handle for interaction with the latch. In addition, the technical result of the present invention is achieved by the fact that the revolver is equipped with a hammer, rotating around a movable spring-loaded axis. This ensures the return of the working valve stem to its original position in a simpler and more reliable way than in the prototype sample, and the valve opening time can be adjusted by the force of spring preload during assembly of the revolver.

 The cartridge is equipped with 40 ball bullets (eight channels of 5 bullets each). The selected number of bullets is due to the fact that it is in the region of the fortieth shot that the dispersion of the characteristics of gas cylinders and a sharp drop in pressure begin.

 A multiply charged gas cylinder revolver consists of the following main components and parts: a housing (1) with a trigger guard (2) and a cover (3), used to assemble the revolver and connected by three screws (4, 5 and 6). The lid and body are provided with reflexed wooden plates (7). The composition of the revolver includes the barrel (8) and the fixed part of the drum (9), designed to accommodate the tube (10), which serves to disperse bullets. The barrel and drum are attached to the body using the axis of the clamp (11). A cartridge (12) is assembled on the drum. The gas cylinder system of the revolver includes a gas cylinder (13), needle (14) and working (15) valves connected by a connecting pipe (16). The revolver contains a trigger (17) with an axis (18), a mainspring (19) and a power sear (20), as well as a spring-loaded striker (21). The trigger mechanism consists of a trigger (22) with an axis (23) interacting with the trigger auto-sear and parts of the mechanism for turning the clip, a single sear (24) interacting with the trigger and equipped with a spring (25), the sear lever (26), which communicates between trigger and a single sear, as well as a fuse (27) with an axis (28). A pressure cover (29) with an axis (30), a screw with a cup (31), a latch (32) and a lock (33) located in the lower part of the revolver handle.

 The fixed part of the drum (9) consists of a cylindrical body (34), an obturator (35) with an obturating spring (36) and a cage rotation mechanism (Fig. 5), which includes a slider (37), a two-arm lever (38) with a latch ( 39), interconnected by an axis (40) and a return spring (41), designed to return parts of the trigger mechanism to its initial position through the slider.

 The cage assembly (12) (Fig. 4), which is a multiply charged rotating magazine, consists of a housing (42) with eight longitudinal cylindrical channels for accommodating ball bullets (43), feeders (44) and feed springs (45). In order to maximally approximate the shape of the outer surface of the cage to the outer surface of the original sample, recesses "A" and "B" are made on it. At the same time, the recesses “A” serve to fix the position of the clip using a latch (46) placed in the housing in front of the trigger (Fig. 5).

 On the surface of the housing facing the holder with the drum, a special protrusion of the feeder (47) is made, which, when assembling, is included in the circular groove "B" of the holder.

 On the surface of the lid there is a door (48) (Fig. 9) on the axis, which serves to equip the drum with bullets. When filling the channels of the holder, the door is tilted, and the filling is controlled through the slots "G" of the holder. The tube is fixed to the drum with a screw (49).

 The auto-sear to ensure the free return of the trigger to its original position is equipped with a spring (50) located between the surfaces of the auto-sear and the trigger.

 The operation of a multi-charged gas balloon revolver provides four modes: charging (equipment) of the revolver; shooting without self-cocking; self-cocking; reloading.

 Charging (equipment) of the revolver is as follows. When fingers press on the latch (33), the latch (32) is released and the pressure cover (29) is folded. The screw with the cup (31) must be set to its lowest position. A gas bottle (13) is inserted into the handle cavity and pressed against the needle valve (14) when the pressure cover (29) is closed. The final fixation of the cylinder (13) is carried out by a screw with a cup (31). In this case, the cylinder is pierced by the valve needle and gas flows through the connecting tube (16) into the cavity of the working valve (15). To equip the cage (12) with ball bullets (43), the door of the lid is diverted to the side and five bullets are inserted into the open cavity of the cage, after which the cage is rotated and bullets equip the next cavity, which is opposite the open door. When filling the eighth cavity, the first of the filled cavities is above the tube, and one of the bullets in the tube (10), because when turning the cage in the last section, it interacts with the protrusion-feeder (47), which lowers it into the tube. At the same time, the obturator (35) is tightly pressed against the seals of the working valve. Thus, after filling the last cavity and closing the shutter, the revolver is ready to fire without self-cocking.

 Shooting without self-cocking is as follows. The shooter turns the trigger (17) with the thumb of his right hand before placing it on the ledge of a single sear (24). The pull of the trigger does not cause the action of the arrow parts of the revolver mechanism. When you press the trigger (22) with a very small rotation using the axis "E" (Fig. 8), the lever (26) rotates, squeezing a single sear (24). The trigger (17) under the action of the mainspring (19) rotates around the axis (18) and hits the hammer (21). The drummer, rotating around its axis, transfers the force of the impact to the striker of the working valve, which allows gas to enter the tube. A shot is taking place. The return spring of the working valve acts on the firing pin, raises the firing pin, which allows you to reliably close the working valve. Shooting without self-cocking can be done after the revolver is fully loaded and, if necessary, conduct targeted shooting. In the latter case, the drum is turned manually before each shot, and the trigger pull is several tens of grams.

 Self-cocking is carried out after aiming by pressing the trigger (22). At the same time, the latter, interacting with the auto-sear (20) of the trigger (17), turns it away and simultaneously moves the slider (37) forward of the clip rotation mechanism. The slider moves forward through the groove "G" (Fig. 3) and rotates the lever (38) around the locking axis (11), which rotates the clip 45 degrees through the latch (39). When the cage is rotated, the next bullet interacts with the protrusion (47), lowers into the tube (10), and the obturator (35) is first pulled back due to the figured groove on the inner surface of the cage, compressing the spring (36), and after the end of the rotation of the cage is fed forward closing the phone. The horizontal section of the "Zh" groove provides loading earlier than the trigger’s auto-sear falls off the trigger, which occurs when the trigger moves to 44-45 degrees. Since the angle of the trigger when shooting without self-cocking is approximately 50 degrees. (Fig. 4), then putting the trigger on a single sear does not occur. When the trigger is returned to produce the next shot, the auto-sear passes it, after which it returns to its original position under the action of a spring (50). The effort to pull the trigger when firing with a self-cocking is a few kilograms and is within the norms for revolvers and pistols.

 The revolver is reloaded after the ammunition is completely used up and must include both the replacement of the gas cylinder and the full ammunition of the clip. To remove the cylinder, press the retainer (33) and open the pressure cap (29). The shape of the pressure cap is selected so that when it is opened, it is possible to reliably take the balloon with your fingers and remove it from the handle cavity. In this regard, the wooden lining (7) is made up of two parts. The upper parts of the plates are located on the body (1) and the cover (3), and the lower parts, respectively, on the left and right sides of the pressure cover. Further operations are similar to loading operations.
