Description

The invention relates to projectiles for throwing projectiles without the use of Soybean charges, namely, an air rifle for throwing harpoons.

The purpose of the invention is to increase the reliability of the gun by simplifying its design, as well as ensuring that the receiver is pumped with air and that the gun is operated at various JQ air pressures in the receiver.

The drawing shows a cost-free airgun in the position of its parts after the shot ,,

The cost-free airgun 15 contains a receiver 1 with a handle 2 having a trigger lever 3, a spring 4 connected at one end to the trigger lever 3j a barrel 5 installed in the receiver 1 and connected to it 20 muzzle 6 and bottom 7 parts of a muzzle 8, piston - pusher 9 placed in the barrel 5, fixed in the bottom 10 of the barrel 5 valve AND with the gate 12 uncoupling the channel 13 of the barrel 25 5 with the cavity 14 of the receiver 15 placed behind the valve 11 actuator made in the form of the housing 15 with the longitudinal channel 16 and installed this kana le 16 of the execution piston 17 connected to the valve 12, valve 110

In a cost-free air rifle, the longitudinal channel 16 of the housing 15 of the executing device 35 is made through a through trigger lever 3 adapted to interact with the executive piston 17 and is spring-loaded to it with its spring 40

In the piston-pusher 9, gne-40 zdo 18 is made with element 19 for connection to the harpoon shank, and the muzzle 8 is made removable

The rifle is equipped with a regulator 20 of the tension value of the spring 4 of the trigger lever 3 installed in the handle 2 and connected to the second end of this spring 4c

50 Regulator 2 tension values pru

4 of the trigger lever 3 is made in the form of screws and nuts0

The valve 13 has a working cavity 21 communicated by the radial holes 22 with the cavity 14 of the receiver 1 o

The shutter 12 of the valve 11 is spring-loaded prukin 23 in the direction of locking the valve I1 „

The trigger lever 3 has a shoulder 24, interacting with the rear end of the executive piston 170

The longitudinal channel 16 is communicated with the cavity 14 of the receiver 1 channels 25o

The no-cost pneumatic gun works as follows

For pre-operation injection of the working fluid-air into the cavity 14 of the receiver 1, a muzzle is removed. 8C The harpoon is connected via a connecting element 19 with the piston-pusher 9 and the last of the channel 13 of the barrel 5 is removed. trunk 5, valve II, its working cavity 21 and radial holes 22 enters the cavity 14 of the receiver 10. At the same time, the shutter 12 under the effect of the pressure force supplied by the working medium source retracts, the spring 23 turns back, and opens the valve 14o. and pumping air from the receiver 1 the desired pressure source is disconnected pressure in the duct 13 falls barrel 5 and the spring 23 moves the valve 12 forward, resulting in the latter closes the valve 11 and closes the receiver 1 za- kachanky air into it. After separating the source of the working fluid from the gun, the piston-pusher 9 and the muzzle 8 are installed in their place in the gun

In the process of charging a gun, a harpoon is inserted through the muzzle 8 into the bore 13 of the barrel 5. At that, the harpoon moves the piston-pusher 9 through the bore 13 of the barrel 5 to knotted into the valve 110. between him and valve 110

The pressure of the compressed air, when reaching a value greater than the force of the spring 23, opens the valve 11 and the compressible gas penetrates the receiver 1, further increasing the pressure of the air in the receiver. After the piston 9 pushes 9 into the valve 11, the latter is closed. acting on the harpoon or on the piston-pusher 9, holds them in the rearmost position. Shotgun zarozhen and prepared to shoot

To fire a shot, the shooter presses the trigger lever 3, overcoming the resistance of the spring 4. The shoulder 24 of the trigger lever 3 is deflected.

back and removes the effect of the spring 4 on the actuating piston 17. By applying air pressure in the cavity 14 of the receiver 1, flowing through the channels 25 into the channel 26, the executive piston 17 moves backward, pulling the valve valve 12 apart P. The valve 12 moving back opens the valve 11 and the air from the cavity 14 of the receiver 1 flows through the radial holes 22, the working cavity 21 and the valve 1 1 into the channel 13 of the barrel 5 and acts on the piston-pusher 9 “It moves the harpoon 5 along the shaft 5 At the end of the working Porgaen's stroke - the pusher 9 catches 8 muzzle.

After the shooter removes the trigger lever 3, it returns to its original position with a spring 4, and with its shoulder 14 returns the actuating piston to its initial position. The shutter 12 moves forward and closes the valve 11.

the next shot is fired for the next shot
