The second bottom can be made separately and inserted into the cylinder with the possibility of axial displacement.

 According to a second embodiment of the invention, the munition for a firearm using a liquid propellant contains an element in the form of a cylinder liner with a bottom in which there is an axial hole, and an ignition device and a shell made of sealed combustible material capable of changing size and shape placed in the shell the bottom hole is axially biased with a sleeve with an axial gas channel that is blocked by an elastic quick-burning diaphragm, a shell is attached to the sleeve with the lower part, n and on the outer surface of the bottom, coaxial to the hole, a groove is made and a series of holes are made connecting the groove with the igniter located at the bottom, an annular capsule is installed in the groove. The bottom can be made separately and inserted into the cylinder with the possibility of axial displacement. On the opposite side to the bottom, the cylinder is made with an end rounded wall, in which a hole is made, closed by a quick-burning stopper.

 In FIG. 1 shows a holder for a projectile for a firearm using a liquid propellant containing an element in the form of a sleeve, which has a cylinder 1, a bottom 2 and a second bottom 3. In the bottom 2 there is an opening 4 in which a sleeve 5 having a gas-conducting channel 6, which is blocked by a diaphragm 7 of quick-burning elastic rubber. The sleeve 8 is attached to the sleeve 5 by a shell 8 of quick-burning sealed material. At the bottom 3, an igniter 9 and capsule 10 are installed.

 In FIG. 2 shows an ammunition for a firearm using a liquid propellant containing an element in the form of a sleeve that has a cylinder 1, a bottom 2 and a second bottom 3 with rounded edges. The bottom 2 is made separately and inserted into the cylinder 1 with the possibility of axial displacement. In the bottom 2 there is an opening 4 in which a sleeve 5 is inserted with axial displacement and has an axial gas-conducting channel 6, which is blocked by a diaphragm 7 made of quick-burning elastic rubber. To the sleeve 5 is attached the lower part of the shell 8 of a sealed quick-burning material. At the bottom 2, a groove 9 is made coaxially to the hole 4, and a series of holes 10 are made connecting the groove 9 with the ignition device 11. In the groove 9, an annular capsule 12 is installed. At the bottom 3 there is an opening 13 closed by a plug 14 of a sealed quick-burning material.

 The second bottom 3, similarly to the bottom 2, can be performed separately and installed in the cylinder 1 with the possibility of axial displacement.

 In one embodiment, the ammunition contains only cylinder 1 and bottom 2, bottom 3 is not performed and is not installed. Accordingly, the ammunition has reduced dimensions and weight.

 The ammunition described above is also filled with powder propellant charges. In this case, depending on the embodiment, the propellant propellant charge is placed either under the shell inside the sleeve or directly in the sleeve without the shell.

 Ammunition for firearms using the liquid propellant shown in figure 1, operates as follows. Ammunition is sent to the chamber of the drum of the weapon. The drum rotates to align the chamber with the ammunition with the needle. The needle moves into the chamber, pierces the diaphragm 7 and enters under the sheath 8. A liquid propellant charge is supplied through the needle, which presses the sheath 8 against the walls of the cylinder 1, bottom 2 and the ignition device 9. The needle is pulled out of the ammunition, the diaphragm 7 is compressed at the puncture site. The drum rotates to align the camera with the ammunition with the shutter channel. The hammer strips the capsule 10, from which the igniter device 9 is activated, which ignites the shell 8 and the propellant charge. The propellant charge, the shell 8 and the diaphragm 7 are burned out, the gas cylinder 1 and the bottom 3 are pressed against the walls of the chamber. The sleeve 5 under gas pressure is displaced in the hole 4 of the bottom 2 and is pressed against the end of the barrel. Gases through channel 6 enter the shutter channel and then into the barrel channel. After the shot, the shutter, to feed another shell into the barrel, moves the back of the camera. In this case, the back of the bolt passes through the channel 6 into the cylinder 1. The bolt moves forward and its rear part leaves the ammunition and the chamber. The drum rotates, the used ammunition is extracted from the chamber.

 Ammunition for firearms using the liquid propellant shown in figure 2, works as follows, figure 3. The ammunition is sent to the chamber 15 of the drum 16. The drum 16 is rotated to align the chamber 15 with the ammunition and the needle 17. The needle 17 moves into the chamber 15, pierces the diaphragm 7 and enters the inside of the ammunition. Through the needle 17, a liquid propellant charge is supplied, which fills the volume under the shell 8, pressing the latter against the cylinder 1, bottom 2, bottom 3 and the ignition device 11. The needle 17 is pulled out of the ammunition, while the diaphragm 7 is compressed at the puncture site, ensuring the tightness of the volume under the shell 8. The drum 16 is rotated to align the chamber 15 with the filled ammunition with the shutter channel 18. The firing pin 19 pierces the capsule 12, the beam of fire passes through the channel 10 to the ignition device 11, which fires. The igniter device 11 ignites the shell 8 and the propellant charge 20, which burn out, and with them the diaphragm 7 and the plug 14 burn. By gas pressure, the bottom 2 is displaced relative to the cylinder 1 and pressed against the frame 21 and the barrel end 22, the sleeve 5 is displaced in the bottom hole 4 2 and is pressed against the end of the barrel 22, cylinder 1 and bottom 3 are pressed against the walls of the chamber 15. Gases through the channel 6 enter the bore 18 and then into the bore 22, through the hole 13 part of the gas enters the gap between the bottom 3 and the walls of the chamber 15 than prevents adhesion of the bottom 2 to the wall cameras 15. After the shot, to feed another shell 23 into the bore 22, the bolt 18 moves back into the chamber 15 and passes through the channel 6 of the sleeve 5 into the cylinder 1. The bolt 18 moves forward, sends the projectile 23 into the bore 22 and completely exits from the channel 6 of the sleeve 5. The drum 16 is rotated. Used ammunition is extracted from chamber 15. Etc.

 Ammunition for firearms using liquid propellant filled with a powder propellant charge works as follows. Ammunition, filled with a charge, is fed into the chamber 15 of the drum 16. The needle 17 does not move into the chamber 15, and the liquid propellant is not supplied. The camera 15 with the ammunition is combined with the channel of the shutter 18, then the work is performed according to the procedure described above.

 The ammunition depicted in figure 1 and figure 2, containing cylinders 1 and bottom 2 and not containing a second bottom 3, work as follows. The supply of ammunition in the chamber and filling them with charges of liquid propellant is carried out in the order described above. In this case, the shells 8 are advanced from the cylinders 1 and pressed against the walls of the chambers, then the work is carried out in the order described above. After combustion of propelling charges, shells 8 and diaphragms 7, gas pressure bottom 2 and sleeve 5 of the ammunition depicted in Fig.1 and Fig. 2, pressed against the end of the barrel and the frame of the weapon. Further, the work is carried out in the order described above.
