Description

The field of technology to which the invention belongs

The invention relates to the field of small arms and can be used to defeat manpower.

State of the art

A known method of firing a pistol and pistols PM, PKL [Internet: Pistol PM, Pistol compact Lebedev PKL]. The pistol has a barrel, a bolt, a magazine, a device for loading and ejecting a cartridge case, a device for firing single shots.

Before firing, the shutter is manually cocked, a cartridge is sent into the bore, the trigger is pressed and a shot is fired. The second and subsequent shots are carried out in a similar way, only the cocking of the shutter comes from the energy of powder gases, which, in addition to affecting the bullet, discard the sleeve, due to which the shutter is cocked. In the event of a misfire, the sleeve is ejected when the shutter is manually cocked [Patent. 2747169 (RF).

The method of firing a pistol (Fig. 6) consists in cocking the bolt ZT 15 and the striker BK 19, sending the PT cartridge into the bore of the KS 13, igniting the powder in the PT, firing single shots, ejecting the GL cartridge case, and preparing for the next shot.

The operation algorithm of the PT pistol units before firing is performed with the participation of a simple ST 15 (Fig. 10, 11), in which there is a BK striker 19, a PRSh 20 piston (Fig. 12) with a SPR 22 retaining spring and a BPR striker spring 21, is as follows : the shutter ZT 15 (after firing or manual cocking) is set to the working position (front) (Fig. 6), the PT is sent to the COP 13, the striker BC 19 (Fig. 11) is set to the working position (middle) and held in it by due to the locking spring SPR 22, which abuts against the first slot PPZL 24 of the locking bar ZL 23.

After pressing the trigger SK 9 (Fig. 12), the rocker KM 26 rotates around the axis OKM 27 clockwise and pushes out of the PPLZ 24 SPR 22, which bends (is pressed against the ST 15) and PRSh 20 with BC 19 under the influence of the BPR 21 move forward , BK 19 (Fig.6) strikes the primer of the PT cartridge, a shot occurs.

The operation algorithm of the units of the PS pistol after the shot is as follows: the ejected sleeve GZ (Fig. 6) from the COP 13 takes the ST 15 and PRSh 20 (Fig. 11) to the cocked position (rear), the withdrawal is carried out at any position of the SC 9 (Fig. 12), BPR 21 and ZTPR 16 (Fig. 6) are compressed, the magazine spring PMG 18 (Fig. 7 and 8) pushes the PT up (to the stop with the fired GL, if the shot is not the first, or to the cover of the KZB 8 bolt block, if first shot), ZTPR 16 (Fig. 6) and BPR 21 (Fig. 11 and 12) are stretched, ST 15 (Fig. 6) and PRSh 20 (Fig. 11 and 12) are brought into position.

Shooting with single shots is possible thanks to a special device that contains: a rocker KM 26 (Fig. 12) with a retracting spring OP 30, a retaining spring SPR 22, the tip of which can slide along the ZL 23 locking bar with two slots PPZL 24 and VZPL 25, SK 9 with stroke limiter OX 29.

When cocking the ST 15 (Fig. 11), the sliding of the STR 22 along the ZL 23 occurs unhindered at any position of the trigger SK 9 (Fig. 12), the reverse movement of the SPR 22 is impossible due to slots in the locking bar at any position of the SK 9 (pressed, not pressed, intermediate), so the implementation of a new shot is possible only after the return of the SC 9 from the pressed position and when you press the SC 9 again.

In a misfire, the removal of GL from COP 13 occurs in the same way as in the prototype.

The PS has (Fig. 1, 2, 3, 4, 5 and 6): a barrel (barrel bore KS 13), ZT 15, MG 17, devices for loading and ejecting the GL cartridge case, firing single shots (Fig. 12).

ZT 15 has (Fig. 10, 11, 12) a body in the form of a cylinder with plugs at the ends, which have holes for the translational movement of the BC 19, on which the PRSh 20 with the SPR 22 is fixed, the PRSh 20 piston is affected (pushed) by the BPR 21 in the direction of the bullet's flight.

On ZT 15 (Fig. 6) affects ZTPR 16 in the direction of flight of the bullet, through which the PT is sent to the bore.

After hitting the BC 19 on the primer of the PT, a shot occurs, while the GL is discarded, which moves the shutter of the ZT 15 to the rear position, the ZTPR 16 is compressed, the BC 19 (Fig. 11), PRSh 20 and SPR 22 moves, which bends and slides along the ZL 23 , are compressed by BPR 21.

After the shot (Fig. 6, 7, 8), the fired GL moves back, cocks the bolt and, with the help of the PMG 18 magazine spring and the cartridges remaining in the magazine, is squeezed up.

MG 17 is equipped with antennae (left and right antennae of the LU and PU in Fig. 9), which keep the extreme PT (Fig. 7 and 8) from extruding the PMG 18 until the MG 17 magazine is inserted into the PT handle, after installing the store in the PT, the antennae are unclenched (the mechanism for opening the antennae is not shown in Fig. 9) and do not prevent the movement of the PT.

The PS is equipped with a single shot firing device, which has ZL 23 (Fig. 11, 12) with two slots 24 and 25, KM 26, ODA 30, SK 9 with OX 29. Before the first shot, the striker BC 19 (Fig. 11) must be in the cocked position, BPR 21 is tense (partially compressed), ST 15 (Fig. 6) is in the forward position, ZTPR 16 is relaxed.

For firing single shots, a special device is required (Fig. 11, 12), which contains KM 26 with OPR 30, SPR 22, which can slide along ZL 23 with slots 24 and 25, and SK 9 with OX 29.

If, after the shot, the trigger SK 9 is released, then the SPR 22 falls into the first slot of the locking bar PPZL 24 of the locking bar ZL 23, after another pressing of the SK 9, a shot occurs.

If, after the shot, the trigger SK 9 remains pressed, then the SPR 22 falls into the second slot of the VPZL 25 ZL 23, and after releasing the SK 9, into the first slot, after the next pressing of the trigger, a shot occurs.
