Definitions
- the technical field of the invention is that of counter-masses for weapons without step back.
- counter-masses also called reaction masses
- reaction masses include a charge of inert material intended to balance the momentum when firing to eliminate recoil.
- a counter-mass is ejected by a propellant charge towards the rear of the weapon at the same time as a projectile is launched forward.
- the counterweights generally used are made of solids fragmentable at the exit of the barrel of the weapon, solid produced for example in the form a bundle of plastic filaments.
- the subject of the invention is a recoilless weapon comprising a dispersible counterweight system placement in a barrel of the weapon and ejected when fired at a rear part of it by a piston pushed by the gas pressure of combustion of a propellant charge at the same time as a projectile is launched towards a front part of the tube,

- the cylindrical wall and the partition form a single and same room, the partition comprising at least one breaking point delimited by the wall.
- the cover is bonded to the envelope by gluing and the cylindrical wall has a rear extension forming with the partition a bowl receiving the piston.
- the charge of inert material is a liquid composed of water and an anti-freeze agent like calcium chloride.
- the material of the wall, the partition and the cover is a material polyphenylene oxide plastic.
- the cylindrical wall is placed in a clearance provided at the rear of the tube, clearance having a diameter such that the internal diameter of the wall placed in the tube is equal to the diameter internal projectile guide at the front of the tube and the end of the rear extension of the wall bears against a shoulder of the tube, shoulder connecting the clearance to the internal diameter of the projectile guide.
- the cylindrical wall is formed by three sections joined together.
- the cylindrical wall can be extended to the rear part of the tube by a spacer integral in translation with the latter and of the same internal diameter as Wall.
- the spacer can secure the translation of the wall and the tube tear.
- the cover has a conical shape converging towards the rear part of the barrel of the weapon and includes an orifice for filling equipped with a closing screw and a sealing washer.
- the cover has a corrugated wall making it possible to contain the expansion of the liquid caused by temperature variations.
- the piston has a sealing device preventing any material leakage inert.

It can also include a seal arranged in a groove arranged on the external diameter of the piston, and making it possible to ensure dynamic and static sealing.
- a recoilless weapon 1 is shown schematically in section.
- This weapon includes a cylindrical tube 2 axis 3, which is made for example of filament wound. Inside the tube are arranged a projectile 4, a case 5 containing a propellant charge and a counter-mass dispersible 6.
- the projectile 4 carries on its rear part stabilization fins not represented. They are folded along the body of the projectile and inside the tube 2 and deploy when the projectile leaves the tube.
- the housing 5 comprises a tubular wall 8 closed by a rear wall 7 forming a single piece and a front wall 9.
- the tubular wall 8, the rear wall 7 and the front wall 9 define a volume internal 10 intended to receive a propellant charge of known type of the powder type single base or double base glitter.
- a black powder igniter 11 of known type is also arranged in the internal volume 10 at the axis 3. It is connected by wires to a setting device gun fire.
- the tubular wall 8 has at its median part a primer annular rupture 12 of triangular profile intended to divide the case in two pistons as will be explained later.
- a primer annular rupture 12 of triangular profile intended to divide the case in two pistons as will be explained later.
- Such a case is described in the patent FR-A-2 697 327.
- Counterweight 6 consists of an envelope 13, a bottom 14 and a cover 15 which delimits an internal volume filled with an inert material 16.
- the envelope 13 consists of a cylindrical wall 23, adjusted in a diameter internal 20 of the tube 2 and made integral in translation with the latter, for example by collage.
- the bottom 14 consists of a partition 27.
- the cylindrical wall 23 and the partition 27 form a single piece, and are delimited by a primer rupture 24 which is intended to facilitate their separation.

- an anti-freeze such as calcium chloride.
- the addition of calcium chloride allows the weapon to be used at temperatures below 0 ° C. In addition, its fairly high density reduces the volume of the counterweight.
- the proportion of calcium chloride will preferably be around 30%.
- the wall 23 has, beyond the partition 27, a rear extension 22 which forms a bowl 17.
- This bowl is intended to receive in part the housing 5.

- the pressure communicated to the liquid 16 via the piston breaks the cover 15 in small fragments.
- the liquid 16 is pushed towards the rear of the weapon in the direction Y.
- the wall 23 guides the piston 18b including a peripheral rim conical 35, coming from the rupture initiator 12, remains in contact with the wall under the pressure generated by the charge combustion gases, so as to ensure gas tightness (see patent FR-A-2 697 327 which describes such a piston).
- FIG. 3 represents a second embodiment of the counterweight according to the invention.
- a recoilless weapon 1 comprises a tube 2 inside which a projectile 4 is arranged, a case 5 containing a propellant charge and counterweight 6.
- the tube 2 has two internal diameters different 19 and 20 connected together by a shoulder 25.

- the cylindrical wall 23 of the counterweight 6 is made integral with the tube 2, by example by gluing, at clearance 19, the end of the extension rear 22 of the wall being in abutment against the shoulder 25.
- the internal diameter of the cylindrical wall 23 is equal to the internal diameter 20 of the tube.
- This variant facilitates the production of the box 5 which has only one external guide diameter with the tube 2 and the wall 23.
- the housing guide is sliding in the cylindrical wall and the tube.
- the wall 23 is extended to the rear part of the tube, at clearance 19, by a spacer 21.
- the spacer 21 improves the connection in translation of the wall to the tube and therefore counterweight.
- Figure 4 shows the weapon at the time of the separation of the case into two pistons after ignition of the propellant charge.
- the gas pressure pushes the projectile in direction X via piston 18a and counterweight 6 in direction Y via piston 18b.

- the counter-mass 6 forms a sub-assembly which can be made integral with the clearance 19 of the tube 2 for example by gluing.
- the cylindrical wall 23 of the counter-mass is produced in three sections 23a, 23b and 23c joined together, for example by gluing, at the level of thinning 40 of complementary shapes made on each of the three sections.
- the rear extension 22 of the section 23a abuts against the shoulder 25 of the tube 2.
- the bottom 14 consists of a partition 27 which forms with the section 23a one and the same room.
- the partition 27 has a breaking point 24 intended to facilitate its separation from the cylindrical wall 23.
- the partition conforms to the shape of the piston 18b which has an internal cup 41 and an annular lip 36 at the level of its diameter external.
- the section 23b of the wall 23 is integral with the cover 15 and forms a single and even room with the latter.
- the cover has a corrugated wall which allows contain the variations in volume of the liquid 16, expansions which may occur following temperature variations.
- the section 23c of the wall 23 extends to the rear part of the tube, but alternatively it is possible to provide a shorter section 23c which would be extended by a spacer to the rear of the tube, spacer of the same internal diameter that the cylindrical wall 23.
- This alternative embodiment makes it possible in particular to produce the counterweight under form of a complete sub-assembly after assembly of the sections 23a, 23b and 23c, that can be introduced inside the barrel of the weapon and secured in translation with this last.
- Figure 6 shows the weapon at the time of the separation of the case into two pistons after ignition of the propellant charge.

- the seal between the piston 18b and the liquid of the counterweight is provided by the annular lip 36 which, when the pressure increases liquid generated at the start of the blow, comes into contact with the cylindrical wall 23.
- This tightness is here further improved by the partition 27 which, after rupture, has also a lip which is applied against the walls of the envelope.
- the cylindrical wall 23 is torn off by the lip 36 of the piston 18b at assembling sections 23a, 23b and 23c, these can be made with a diameter different internal.
- the section 23c could have an internal diameter slightly greater than the internal diameter of the previous section 23b which itself could have a diameter slightly greater than the internal diameter of the section 23a.
- the variation in diameter would be very small and of the order of a few tenths of millimeters, thus sealing would always be achieved thanks to the ability to deformation of the lip 36 and of the partition 27 which is greater than the variation diameters.
