Trigger mechanism is installed on small arms of a carriage-mounted gun of a bullpup configuration with prior recoil of a firing device inside its guide bed, equipped with the right and left gun handles. A trigger mechanism comprises the following: a figured spring-loaded slider trigger element with two triggers, a muzzle ledge, acting at a transversely moving spring-loaded strut of a full bent in the front position of the firing device, and a breech ledge of the trigger element acting at the strut. The breech ledge is installed on a spring-loaded cam available on the slider trigger element. The breech and muzzle full cocks of the slider trigger element are installed at the distance, the value of which provides for locking of the spring-loaded hinged cock in the cocked position immediately after the first shot in the "fixed" burst firing mode. The trigger mechanism comprises a cock moderator to reduce the firing rate in the "burst of arbitrary length" mode. The longitudinal figure slider trigger element is placed on the carriage-mounted gun equipped with a basic longitudinal metal element, which carries the movable firing unit and metal bases of weapon gun handles. The return spring of the trigger element is placed on a breech rod of the slider trigger element with a rest of the muzzle end at the crank transition of the trigger element, and of the breech end - at the breech wall of a seat for this spring.

The invention relates to the field of armaments, particularly to individual small arms, and is designed to defeat enemy forces. The machine holds the barrel to the receiver, which placed the trigger mechanism, stock, store /see, for example, a Material part of the small arms" edited AOR. - M.: "Barongis", 1945, str-332/, which describes an automatic weapon: PPSH, RPD, etc. But as a legacy samples are taken from the Armory. Currently adopted is widely known AKM I. on the basis of other small arms /see "basic military training" edited Whanaunga. - M., Chamberlain, 1983, p.86-105/. The machine holds the barrel to the receiver, stock and store, the shutter return mechanisms, the trigger mechanism. In the trigger mechanism includes a moderator trigger to stabilize the barrel before the next shot. However, the hammer from striking the moderator before hitting the drummer and also directed below the axis of the barrel has an impact on the quality of automatic fire, and high rate of fire is not always justified. The objective of the invention is a cost - effective use of weapons. This object is achieved in that the machine containing the barrel to the receiver, butt and store the n, the shutter return mechanism, the trigger mechanism with the moderator of the trigger, the moderator of the trigger is made in the form of a plate, loosely planted one end to the axle and is constantly in contact with the tail of the hammer as with a roller, and without it, and on the same axis set another plate of the regulator of the rate of fire, interacting with the eccentric washer for setting the pressure of the spring on the moderator trigger mounted between the plates. The design of the machine is made under an intermediate cartridge, 7.62-mm sample, 1943 Figure 1 shows a General view of the machine, figure 2 and 3, the front and rear part of the receiver, figs.4 and 5 - views of the front and rear ends of the shutter and figure 6 is a top view of the trigger mechanism. The machine includes a barrel 1, the receiver box 2 with a lid 3 which is placed in the trigger mechanism containing the trigger 4 trigger 5. On the trigger made the protrusion 6 under the sear 7 self-timer lever 8 and the projection 9 of the trigger, and the protrusion 10 under the sear 11 with the lever 12 mode single combat, interacting with the sector 13 of the translator. On the tail of the trigger is a roller 14 that interacts with the plate-moderator of the trigger 15, which communicates through the spring 16 with the plate-regulator of the rate of fire 17. The adjustment is made eccentric W is boy 18. In the trigger mechanism includes combat spring 19 and the spring 20, common to timer lever and lever single combat. In the receiver placed the bolt 21 with the return spring 22. The shutter is placed drummer 23 held by the pin 24, which is in mine. The shutter made Bolognese 25 for the cartridge-ejector sleeves 26 and grooves 27 under the folds 28 of the receiver and the groove 29 under the reflector liner 30. In the trunnion 31 of the shutter made a hole for the stem 32 of the gas piston and the groove 33 under the tab 34 on the handle 35 of the bolt to lock the latter. The handle itself freely planted on the gas piston and fixed the washer 36. The hammer is cocked when the drain bolt back safety ledge 37, which also removes the timer lever in the return of the shutter to the trunk. The groove under the bolt handle in the lid of the receiver front ends curved section, performed in the receiver, and has a top 38 and bottom faces 39 and stopper 40 moderator of the trigger. Working machine as follows. When the trigger is pulled, its 5 lug 9 releases the trigger. The trigger turns up, and his tail with roller 14 or without it runs in the retarder 15 and, after compressing the spring 16, strikes the firing pin 23. Is shot. Under the influence of the powder gases of the gas piston rod 32 t is lket back the handle 35, bringing it to the ledge 34 of the groove 33 of the axle bolt. The handle moves up and down through the top face 38 of the curved section of the groove against Casey arrows. Opening the shutter arm with the back of his base pushes the bolt back, compressing the return spring 22. The protrusion 37 of the shutter vvodit the trigger and releases the lever 8 self-timer, sear 7 which locks the trigger due to its protrusion 6. The reflector 30 ejects through the slot to the right of the cover 3 of the receiver 2 sleeve. When returning the shutter forward he takes the top round from the magazine. The bolt handle after its contact with the end of the stem continues to move onward and upward through the bottom face 39 of the groove and the protrusion 34 is included in the groove 33. The shutter is locked. Sector 12 the interpreter in figure 2 is the provision of automatic fire, and figure 3 - mode single fire, and to repeat the shot, you need to release the trigger, then click on it. The position of the sector 12, shown in figure 3 by the dashed line means that the machine put on the fuse. The axis of the cartridge coincides with the bottom forming chamber that avoids uticaria bullet in the end of the stem. Plate 17 with eccentric washers 18 compresses the spring 16. Retarder 15 trigger becomes more rigid, increasing the time its running roller 14 of the trigger 4. The rate of fire so about what time is reduced, allowing more rationally ammunition. Automatic weapons, containing the barrel to the receiver, stock, market, the shutter return mechanism, the trigger mechanism with the moderator of the trigger and regulator of the rate of fire, characterized in that the retarder hammer made in the form of having the opportunity to interact with the tail of the trigger plate, freely planted one end to the axle, and the regulator of the rate of fire is made in the form set out on the same axis, the other plate interacting with the eccentric washer for adjusting the pressure force of the spring on the moderator trigger mounted between the said plates, thus to ensure the interaction of the plate with the tail of the trigger last provided with a roller.
