Description

A GUN SUPPRESSOR WITH GAS SPLITTING

Field of the invention

The invention belongs to the field of firearms and firearms accessories, more precisely, the invention belongs to the field of silencers. This invention relates to a gun suprressor with gas splitting.

Background of the invention and the technical problem

Firearms are any weapon that uses gunpowder gases as well as propellant gases to propel a projectile from a barrel. The combustion of gunpowder gases causes each firearm to heat up and to have a recoil, sound traces, and light traces. These four phenomena cannot be avoided, however, some of them can be mitigated. For this purpose, various flash hiders, sound suppressors, and shock absorbers are used.

The sound signal or a bang generated by firearm firing is one of the main reasons for the development of various types of silencers. The burst intensity of a firearm shooting is such that it can permanently damage hearing at the very first shot if the person is near the muzzle of the rifle and does not wear ear protection. Any noise that is of higher intensity and lasts for a long time is harmful to human health. In some cases, the burst of a firearm is sought to be concealed solely for not betraying the position of the gunner or making it more difficult to trace. This is particularly important for special operations by the army and police. When shooting indoors, the problem of bangs in firearms is even more pronounced and harmful to the shooter and the people around him. The light trail is more pronounced at dusk and when shooting with a firearm at night, which can in some cases be fatal for the user of the firearm, as the light can betray the position of the shooter, confuse him with the flash effect, or reduce his vision abilities and consequently short-term decrease his ability to fight.

A sound suppressor or a silencer is an accessory that is placed on a barrel of a weapon or is an integral part of a weapon and serves to reduce the sound that the weapon produces when firing, as well as to suppress the effect of flash when hot gases leave the barrel of the weapon. The first silencer appeared on the market more than 100 years ago. The reduction of sound signal and fire, or flash, thus has many advantages both for the user of the firearm carrying a sound suppressor and for people and animals located near the gunner.

The recoil of the firearm either takes the shooter's gaze away from the target or redirects it a little. This negatively affects the accuracy of shots that follow each other in sequence. The faster the shots follow each other, the more critical it is that the weapon is manageable. Even when a gunner shoots at several different targets or when they are moving, the time spent retargeting the weapon against the target must be kept as short as possible. The recoil of the firearm, on which a sound suppressor is mounted, is reduced by the forces acting in opposite directions. Gunpowder gases traveling at high force and speed from the barrel of the gun to the surrounding area collide with the inner surfaces of a sound suppressor, forcing weapons from the shooter's hands away from it, while the forces exerted on the shooter's shoulder or wrist are mainly due to the kinetic energy of gas reflection from the projectile fired and through the bottom of the empty cartridge case, the locking mechanism and other parts of the weapon to the gunner. When the projectile leaves the barrel of the gun, the gases continue to push the bottom of the cartridge case for some time until they lose their thrust power.

In addition to the above, increasing attention is paid to the gases that the gunner inhales during firing with semi-automatic and automatic weapons on which a sound suppressor is installed. These gases are known to be toxic. The more gases leave the outlet ports of a suppressor, the fewer gases are received by the user of semi-automatic and automatic firearms through the ejection port with a sound suppressor fitted. An excessive amount of reflective gunpowder gases from a suppressor through the barrel back to the locking mechanism has a bad effect on the operation of semi-automatic and automatic firearms and reduces the lifespan of the weapon.

Any attached device to a gun barrel that limits or slows down the exit of gases into the environment causes a reflective effect of gases and unburned gunpowder particles back into a gun barrel and through it through the ejection port of the semiautomatic or automatic rifle into the face of the gunner, or proximity to the face of the shooter, who then inhales these gases. This phenomenon cannot be completely reversed. It is known that gunpowder gases derive from the ejection port of semi-automatic and automatic weapons even if no sound suppressor, flash hider, or compensator is fitted to the weapon. In the case of different models of sound suppressors on the market, the reflection of gases from a suppressor back into a gun barrel is greater or less, depending on the design of a silencer, and cannot be changed, without changing the design or the structure of the suppressor.

The technical problem solved by the present invention is the design of a multifunctional suppressor. Primarily, the solution aims to reduce the sound signal strength of the firearm to which it is attached as well as reduce or completely cancel out the flash trace caused by the firearm after each shot is expelled. At the same time, it is desired that the solution also reduces the recoil of firearms. In addition, the suppressor design aims to reduce the amount of back gases from the damper back into the tube to an amount as small as possible.

Prior art

Patent application US2021180902A1 concerns a firearm suppressor consisting of a series of guiding blades for diverting gunpowder gases arranged one after another. Some blades may be directed clockwise, while other blades are directed counterclockwise. Guiding blades in this case limit the tube in which they are installed. The tube is provided with holes that allow gases to pass into other chambers.

Patent US10619963B2 relates to a firearm suppressor consisting of a series of radially distributed tubes with inner barriers that brake gases as they pass through pipes, and a spiral core with inner barriers of various geometric shapes. The pipes must not come into contact with the housing of the suppressor or contact the suppressor housing only at certain points.

The US11125523B2 patent applies to a firearm suppressor that can also be made using the 3D printing method. The interior is designed to divide the initial flow of gases into several paths, most of which are rectangular geometric shapes, and some are semicircular or circular.

The US10753699B2 patent relates to a suppressor, which includes both the primary flow path and the secondary flow path. The primary flow path centrally located in a suppressor consists of several chambers separated by hatches. The secondary flow path, on the other hand, is represented by spirals that are located around the perimeter of a suppressor core. Part of the gases are thus diverted backward, through openings, and then into external spirals bounded on the outside by a suppressor housing. Patent US10393463B1 relates to a silencer for firearms consisting of inner braking flow chambers, preceded by releases in a tubular core that allow gases to flow through the core of a sound suppressor. During the journey through a suppressor, gases change the direction of travel and travel through spiral releases in tubular inserts. A sound suppressor tightens to the compensator due to the exhaust angle on which the gases are forced when leaving a suppressor.

Patent application US5092223A describes a flash hider and a recoil compensator, which generally has an opening upwards from which the escaping gases generate a downward directed reaction force, and an inclined surface on which the propellant gases collide and expand, and deflect both sides and upwards to overcome the natural tendency of the gun barrel to vertical ascent and twist. Below the generally upward opening void, within the floor of the bore of the muzzle is a venturi trough in which a lowered pressure region of propelling gases is created by the high-speed passage of the propelling gases down to the bore of the muzzle brake. This lowered pressure region within the venturi trough is still in excess of the environmental pressure exterior of the muzzle brake so that gases within the venturi trough escape through channels directed downwardly and to the left and right of the projectile path. Gas escaping through these downward, left and right deflected channels is adjustable in flow so that any tendency of the weapon to drift left or right or to move downwardly may be compensated for.

The document US3455203A discloses a muzzle device with a shape different from the present invention.

A patent application US1017003A relates to a silencer that does not have all the characteristics and components of the gun suppressor with gas-splitting according to the invention.

The patent application US5596161A relates to a firearm muzzle flash suppressor comprising a cylindrical body for attachment to the firearm barrel, having a plurality of open-ended helical flutes angled and offset in the direction of rotation of the exiting projectile.

The patent US7302774B2 discloses a flash hider, wherein according to one embodiment, a suppressor apparatus includes an attachment portion adapted to attach to a gun barrel, and a suppressor portion coupled to the attachment portion. The suppressor portion has a suppressor throughbore that is adapted to be aligned with a longitudinal axis of the gun barrel to allow a projectile from the gun barrel to pass therethrough. The suppressor bore is defined by at least one bore surface having at least one expansion groove disposed therein. The expansion groove may be partially-circumferentially disposed about the suppressor bore, or may include a plurality of expansion grooves. In another embodiment, a flash apparatus includes a suppressor portion having a plurality of longitudinally elongated members spaced apart about a circumference of the suppressor bore, each elongated member being separated from adjacent elongated members by a longitudinal slot, at least one longitudinal slot having non-parallel sidewalls.

The patent US7905170B1 relates to a flash hider and a silencer mount. The use of cone- shaped teeth makes it easy to remove the muffler cracking from the fire damper even after prolonged use. Good fire damping, however, is facilitated by inclined concave transition parts.

The patent application US8490534B1 discloses a flash hider that has a central bore for receiving the barrel of a firearm at one end and three tapered tines at the opposing end with a gap formed between each pair of adjacent tines. Just past the muzzle-seat in the central bore is a flared entrance leading to the gaps thereby allowing hot air and combustion gases to expand radially through the gaps between the tines, thereby cooling the hot air and gases. The lateral faces of the tines are stepped to cause turbulent mixing of the cooler air surrounding the flash hider with the exiting gases so as to further expand and cool in order to prevent re-ignition and thereby reduce secondary flash. Long tines help to hide all but direct viewing of primary flash.

The patent application US2014137452A1 relates to a flash suppressor and recoil compensation device for use with a firearm that reduces recoil and inhibits muzzle flash while preventing audible harmonic resonant ringing after the firearm is discharged. This is achieved through the use of an open ended muzzle device that redirects a portion of the high velocity gasses exiting the terminal end of the weapon through asymmetrically placed narrowing exhaust openings. The asymmetrically placed narrowing exhaust openings gradually direct exiting gases to the rear and to the sides of the muzzle in order to reduce recoil and reducing light emissions. The narrowing exhaust openings are formed by the radially positioned prongs of a distinct weight and width, which widen from the proximal to distal end of the muzzle device. The weight and mass disparity between prongs prevents audible ringing by reducing resonant vibrations between neighboring prongs. The patent US10234230B1 applies to a muzzle device assembly, including a flash suppressor, wherein the flash suppressor comprises a body having a central bore aperture, and wherein the flash suppressor comprises a plurality of air channel inlets and air channels, wherein the air channel inlets and air channels are in communication with the central bore aperture; and a collar, wherein the collar comprises a plurality of airflow apertures, wherein each airflow aperture corresponds to an air channel inlet, and wherein the collar is rotatable between at least an open position and a closed position relative to the flash suppressor, wherein when the collar is in the open position at least a portion of each airflow aperture is aligned with each air channel inlet.

The patent US10655926B2 describes a fire and sound suppressor that has special damping shapes inside, but have different shapes and arrangements compared to the present invention.

Description of the solution to the technical problem

This invention eliminates the shortcomings of the sound suppressor, flash hiders, and recoil compensators described above. The technical problem is solved as defined in the independent claim, while preferred solutions are described in dependent claims.

The essence of the present invention is in the division of gases inside the suppressor into different flows and the ability to adjust at least one of the flows according to the different needs of the user. These flows (also called streams) are allowed by individual parts of the suppressor. The suppressor comprises:

- a tubular housing of any shape and dimension comprising a first (inlet) end and a second (outlet) end,

- a mounting attachment installed at the first end of the housing for attachment to a barrel of the weapon,

- a combustion chamber located closer to the mounting attachment,

- an exit nozzle located at the secod end of the housing, said exit nozzle comprising an opening for the passage of a projectile from the suppressor,

- an inner housing installed inside a part of the housing closer to the exit nozzle,

- at least one gas diverter installed in said inner housing, wherein the gas diverter has a cone-shaped body through which a central bore allowing passage of the projectile, adapted to the caliber of the projectile, is provided, and wherein said the outer surface of the diverter is provided with notches, grooves, or spiral channels arranged to divert and/or inhibit the flow of gases.

The cone-shaped body of the gas diverter may have two, or more, surfaces at different angles along which the gases are directed into one of the streams and has a braking effect on gases. Preferably, several gas diverters are used, which may differ from each other in the orientation of said notches, grooves, or spiral channels, or at the angle at which the notches, grooves, or channels are located. Gas diverters are sequentially installed into each other, forming a path along the perimeter side of one of the gas streams. The sequence of gas diverters is arbitrary and any number of sequence combinations can be used, depending on the desired effect. The dimensions of the gas diverter are adjusted to the calibers of the projectile and the power of the charges, for which an individual model of the suppressor (silencer) is provided.

If gas diverters are positioned in such a way that a large number of diverters with two different notch orientations, grooves, or channels are arranged alternately, e.g. right orientation, left orientation, right, left, the braking effect on flash and sound is greater. If stacked sequentially, first single-orientation diverters (e.g. right) are provided and then diverters with opposite orientation (e.g. left), the braking effect on flash and sound is smaller. If the braking effect is smaller, the recoil increases, and vice versa. If the braking effect is lower, the heating is also lower, and vice versa.

The suppressor housing is in the form of a cylindrical tube and connects all the components of the suppressor and at the same time functions as a combustion chamber on the entrance (inlet) side. Both the external and innner shapes of the housing shall be arbitrary, the shape of the tube being circular or polygonal. The length of the housing may vary and is adapted to the individual model or caliber of the firearm.

At the inlet and outlet ends of the housing, if the movement of the bullet through the suppressor is taken for orientation, threads may be cut to serve to join the mounting attachment or the inner housing. Threads can be left or right. Any other fastening method can be used instead of threads, such as welding, or soldering, or the pieces may be made as an integral part the suppressor, which can be achieved by 3D printing.

The housing can be made of a range of different materials, such as high-alloy steel, stainless steel, steels with varying degrees of carbon, titanium, aluminum, carbon fiber, synthetic materials, etc. The mounting attachment comprises:

- a hexagonal or any other shape for attaching to the mounting attachment to the suppressor housing,

- threads cut on the outer circumferential side, which may be left or right, said threads allowing installation of the mounting attachment to the suppressor housing,

- on the inside, an initial centering surface, optionally followed by threads for the connection with a flash hider or a recoil compensator,

- centering conical surface provided after the centering surface and the threads.

The mounting attachment can be part of the housing and cannot be separated from the housing, which can be achieved by the 3D method of metal printing, milling, welding, and soldering, which means that threads for joining with the housing are not required. However, instead of threads, any other fastening methods can be used.

Inside the suppressor housing the inner housing is provided, wherein the outer side of the inner housing (that is, the one adjacent to the inner surface of the suppressor housing) has channels for diverting or braking gases and fire, as well as braking spirals and final fixed gas diverters. The front of the inner housing, that is, the part of the inner case into which the projectile enters, may have a conical extension, or can be without said conical extension. The inner surface of the inner housing, i.e., the one that is in contact with gas diverter, is smooth. The inner housing shall be fixed or connected to the suppressor housing as well as to the exit nozzle to prevent the gas diverters installed inside the inner housing from falling out. Fastening can be made in any convenient way, or these parts can be made as a single part in the case of 3D printing. Due to different models, the inner housing can be of different lengths, or widths and can be made of different materials. The inner housing can be protected in various ways, such as with various anti-corrosion protections, thermal surface treatments, galvanic protection, etc.

The exit nozzle has openings that allow passage of gases from one of the streams, as well as a bore for the passage of the projectile. On the inlet side of the exit nozzle a cylindrical extension is provided, said cylindrical extention fitting to the rear diverter upon screwing the exit nozzle into the inner housing. The core of the suppressor is the inner housing with gas diverters and the exit nozzle. Openings for the passage of gases of one of the streams may be cut at a certain angle or may be cut parallel to the axis of the exit nozzle. The exit nozzle may also have threads or other elements for joining with the inner housing, wherein welding, embarking, and gluing can also be used. The exit nozzle can be part of the inner housing, which can be achieved by 3D printing.

In addition, the suppressor according to the invention may further comprise a flash hider or a recoil compensator, which is attached to the mounting attachment. The suppressor is then attached to the barrel of the firearm via the flash hider or the recoil compensator. The recoil compensator serves to radially direct gunpowder gases when they leave the barrel of the weapon. The radial diversion of gases may be clockwise and counterclockwise, or the orientation of radial diversions may be sequentially different or alternate, depending on the thread intended to attach the suppressor to the weapon. The radial diversion of gases forces gases into rotational motion in the combustion chamber of the suppressor.

The recoil compensator comprises:

- a base body provided with grooves and channels arranged to divert gases so they are slightly rotated,

- openings offset at a certain angle from the middle of the projectile bore but aligned with the barrel of the weapon and the trajectory of the projectile, so that the gases leaving the barrel of the weapon change direction by reflecting from a front wall of the opening and the grooves as well as gas diverting channels,

- a bore larger than the projectile allowing passage of the projectile, wherein the bore is adapted to the projectile caliber,

- threads or other elements of attachment to the barrel of the firearm and the suppressor housing and the mounting attachment.

The said openings can be divided into several consecutive units or levels, or they can only be single-level. One level of openings comprises four openings perpendicular to each other. Individual openings may be sequentially oriented in different directions and at different angles. Differently oriented gas openings reduce torsional forces transmitted through the recoil compensator to the gun barrel or are created in the structure of the recoil compensator.

Due to the rotation of the gases in the combustion chamber, they are retained in it for more time, releasing energy and, consequently, speed, due to the interweaving of different rotations of gases. If two rotary units are sequentially differently oriented towards each other, the gases interact with each other when swirling, losing their power due to loss of speed. The longer they are retained in the combustion chamber, the more time the gases have to burn, cool down, and thus lose their light effect when they leave the suppressor. The suppressor by the invention is designed to divide the gases incoming into the suppressor through the flash hider or the recoil compensator, or directly from the weapon barrel in the case of installation to the mounting attachment directly, i.e., without the flash hider or the recoil compensator, into several gas flows. Each gas flow has its separate path, but in some cases, two different flows may interfere with each other.

The first gas flow passes from the mounting attachment through the combustion chamber and along the outer side of the conical extension of the inner housing, passing the channels of the inner housing. However, if a suppressor is attached to the flash hider or the recoil compensator a stream of gases passes through the flash hider channels or the recoil compensator channels and then continues its turbulent path through the combustion chamber and the inner housing channels. The gases from this flow exit through the perimeter openings of the inner housing, which are positioned at an angle with left and/or right orientation and/or are positioned parallel to the axis of the suppressor when viewed from the trajectory of the projectile passing through the suppressor.

The second gas flow runs from the mounting attachment through the combustion chamber and the peripheral notches, channels, or grooves of gas diverters. If the suppressor is attached to the flash hider or the recoil compensator, the gas flow passes through the channels of the flash hider or the recoil compensator, through the projectile passage bore, and then continues its turbulent path through the combustion chamber, enters through the opening of the conical extension of the inner housing and continues its journey around the perimeter of the gas diverters. The gases leave the suppressor through the peripheral notches of the exit nozzle. The third gas flow passes from the mounting nozzle through the combustion chamber and the conical surfaces of the gas diverters along their interior. However, if the suppressor is attached to the flash hider or the recoil compensator, the stream of gas passes through the channels of the flash hider or the recoil compensator, passes through the projectile passage bore, and then continues its turbulent path through the combustion chamber, enters through the opening of the conical extension of the inner housing and continues its journey through the conical surfaces of gas diverters and their interior. The gases from this stream can enter the second stream through openings in the rear of the gas diverters, or they may leave the suppressor through the outlet through the central aperture of the exit nozzle.

In one embodiment, gunpowder gases can travel through the suppressor via only two flows, i.e., the second and the third flow. In this example, the gas diverters are stacked one by one in housing D, without the inner housing F. The outer wall of the second stream, the inner side of housing F is replaced by the housing D. The suppressor with its elements is designed in such a way that it can be assembled as optimally as possible for the shooter and his needs. In particular, this concerns the sequences of gas diverters, their number, as well as the presence of the flash hider or the recoil compensator. The suppressor can be disassembled by the user using standard tools freely available on the market.

In some embodiments, however, the suppressor may be assembled in such a way that it cannot be arbitrarily disassembled by the user, e.g. if it is made with 3D printing or if the elements are connected by welding.

In other embodiments, the user can disassemble only part of the suppressor. This is especially the case when 3D printing is used to make the exit nozzle and the inner housing and/or the housing and the mounting attachment as single elements.

All suppressor components may be made of the same material or from different materials. The materials used for making the ndividual parts can be different metals, their alloys with different types of protection, or without protection, as well as some composite materials, carbon fibers, etc. Identical components may also be made of the same material or from several different materials and may have different surface protections. They can be treated with the same anticorrosion protection or heat treatment process. In some cases, there is no need for any anticorrosion protection. All components can be manufactured using various machining processes for metals, casting, injection molding, printing processes with a 3D printer, erosion, forging, etc.

The suppressor according to the invention is preferably designed for semi-automatic and automatic firearms, where it is important not to retain the gases resulting from the combustion of gunpowder gases in the suppressor for longer than is necessary to cool or slow down and burn out. However, it can also be used with all other firearms and may also be fitted to weapons using compressed air or other propellant to propel the projectile.

The gun suppressor with gas-splitting according to the invention will be described in more detail based on exemplary embodiments and figures, which show:

Figure 9 Side view of a flash hider according to a possible embodiment Figure 10 A cross-section of the flash hider shown in figure 9

Figure 11 An elevation view of the flash hider shown in figure 9

As shown in Figure 1 , the suppressor according to a possible embodiment comprises:

- a housing D in the form of a tube of any shape and dimension, having a first (inlet) end and the second (outlet) end,

- a mounting attachment E installed at the first end of the housing,

- a flash hider H mounted via the mounting attachment, the flash hider configured for attachment to a barrel of the weapon,

- a combustion chamber located close to the mounting attachment,

- an exit nozzle G located at the second end of housing D, said exit nozzle having an opening for the passage of the projectile through the suppressor,

- an inner housing F mounted inside the part of the housing closer to the exit nozzle,

- a combination of three types of gas diverters A, B, and C placed in said inner housing F, wherein each gas diverter A, B, and C has a cone-shaped body with a central bore allowing passage of the projectile and adapted to the caliber of the projectile, and wherein the diversters are on the outer circumferential side provided with notches, grooves or spiral channels for diverting and/or inhibiting the flow of gases.

For said diverters, the preferred combinations are AC, BC, and ABC.

Threads are engraved on both the inlet and outlet sides of the housing D, allowing connection of the mounting attachment E with the housing D, as well as the connection of the inner housing F with the housing D. The threads can be left or right. In some cases, any other fastening method may be used to attach individual parts to the housing D, such as welding, or soldering, or the pieces may be an integral part of the suppressor, which can be achieved by 3D printing. The length of the housing D can be different and is tailored to each model, and caliber and is not binding. At the first end of the suppressor housing, the mounting attachment E is provided, thte flash hider H or the recoil compensator J is inserted into it, with which the suppressor is attached to the barrel of the firearm. The mounting attachment has threads E1 engraved on the outer circumferential side, which may be left or right, through which the attachment joins with the housing D. The mounting attachment can be attached to the housing D using a standard E2 key, or a key made specifically for the mounting attachment. Inside, the mounting attachment has an initial centering surface to ensure the axial alignment of the flash hider H, or the recoil compensator J and the mounting attachment E. Threads E3 are engraved behind the centering surface for joining with the flash hider or the recoil compensator. Behind the threads a contact conical surface E4 is provided, which allows alignment and tightening, without applying excessive force. The cylindrical groove E5 serves to reduce the total weight.

Inside the housing D of the suppressor the inner housing F with diverters or gas and fire inhibitors is provided, as well as an brake thread F4 and final fixing deflections of gases with an thread F3 on the outside and a smooth cylindrical shape on the inner surface. On the entry side, when viewed from the direction of the projectile traveling through housing F, an extension in the form of a truncated hollow cone F7 can be located as shown in Figures 1 and 4. The extension cone has a bore that is adjusted to the projectile size and is in any case larger than the intended projectile. Behind the output diverters F3 on the outside of the cylinder a hexagon F6 is provided, for connection of the inner housing F to the housing housing D. Both the external and inner shapes of housing D can be of different tubular shapes, because the round shape shown in the pictures is not necessary. On the circumferential outlet side of the housing F, notches or openings (also called releases) F1 are provided, which allow gases of the first gas flow to pass freely from the suppressor to the environment. The releases F1 are cut over threads F3 to attach the housing F to the housing D and are parallel to each other, and run along the entire circumferential surface, at a certain angle, or are cut parallel to the axis of housing F.

Before the releases F1 and the thread F3 the brake spiral F4 is located, which is in Figure 4 left-oriented, but could also be right-oriented. Between the F4 brake spiral and threads F3 a release surface F9 is provided, which allows gases to rotate before leaving the suppressor. The brake spiral F4 may be longer or shorter, i.e. with a larger or smaller thread pitch, depending on the desired braking effect. The brake spiral F4 is preceded by the release surface F8, which allows gases to swirl.

In front of the release surface F8 gas second diverters F2a are provided and may be oriented in the same way and at the same angles, or oriented equally at different angles. The second diverters F2a are preceded by the first gas diverters F2b, which differ in the angular orientation from the secondgas diverters F2a. Second gas diverters F2a may have the same orientation and at the same angles, or the same orientation at different angles.

Threads F5 are engraved on the outlet inside of housing F for attaching the exit nozzle G, which prevents the gas diverters A, B, and C from failing out from the suppressor. Gas diverters F2a and F2b may also be positioned in different sequence. The first in the plurality can be first diverters F2b, followed by the release rotating surface of F2c and then the second gas diverters F2a.

The number of gas diverters is arbitrary. Also, the length of the cylindrical part of the last gas diverter F2c, F8, and F9 may vary depending on the calibers of the weapon. Also, the angle of diverters can be different and is determined by caliber and charge strength.

At the entrance side of the inner housing F a narrowing is provided that prevents gas diverters A, B, and C from failing out.

The A-type gas diverter is shown in Figure 2, showing at an angle truncated conical shape Ah continuing into a cylindrical part with notches Ag arranged at an angle or in a spiral on the outer circumferential side to divert or brake gases. The gases then continue their journey along the walls of diverters Ad and across the surface Ae. In the middle, bore Aa passes for the passage of the projectile, and the conical shape is defined by two surfaces Ab, and Ac, which have different slopes. The conical surface of Ab or Bb is at a sharper angle than the conical shape Ac or Be, which may also be the other way around. The semicircular gas exchange openings Af are located on the output side of the cylindrical part. There are several semicircular openings Af, but there can be only one. Figure 2 shows the grooves Ai and Bi on the side of gas diverters. The grooves serve to align the diverters one by one and are matched by semicircular extensions Aj and Bj of the gas diverters. The last in a row is always placed diverter C-type, without a semicircular extension. This can be both a type A and type B diverter. In Figure 3, for the purpose of interpreting the technique, both grooves and semicircular extensions are oriented with a 90-degree angle relative to the surface of Ah, Bh, and Ch. The angle can be different, and arbitrary and does not change the basis of the invention and technique.

Various combinations and the number of gas diverters can be installed in the suppressor as shown in Figure 3, where gas A diverters are initially located, followed by gas diverters B, which are separated from each other only by the orientation of the peripheral grooves Ad, Bd, which are intended for gas deflection. The last one is a gas diverter C. In Figure 1 , alternately diverters are arranged A, B, A, B,... B gas diverters also have a Ba bore for the passage of the projectile, surfaces Bb, surfaces Be with different inclinations, a semicircular aperture Bf and notches Bd for gas deflection, as well as an angled truncated conical surface Bh, groove Ai, and a semicircular extension Aj.

From their surface Bd, the gases are reflected at a certain angle acquire a rotational moment, and begin to rotate around the cylindrical surface Be and Ae. The inner surfaces of gas diverters shall be parallel to external surfaces, except at the point where gas diverters are located.

Gas diverters may be stacked sequentially with differently oriented gas diverters as shown in Figure 1 , while in a different embodiment, gas diverters may be stacked with external gas diverters with the same orientation one after the other, as shown in Figure 3.

The part of the gases that leave the barrel of the gun and are diverted to the flow of gases around the surface of gas diverters can be influenced by changing the order of the gas diverters type A and type B, thus achieving less heating of the suppressor core as the gases leave the suppressor earlier. However, a vice versa situation can also be achieved if the sequence of gas diverters is positioned in such a way that the inhibitory effect on gases is greater. The layout of such an arrangement of gas diverters is shown in Figure 1 , A-B-A-B,... The gas diverters positioned in this way reduce the sound level at the output of the suppressor and increase the braking effect on the gases, thus reducing the flash effect.

Two differently oriented gas diverters with peripheral gas diverters are diverters, which have circumferential gas divertors oriented at right-oriented angles or to the left when viewed from the gas diverter axis. Gas diverters may also differ from each other in other properties. For example, they can be made of different types of materials. Thus, gas diverters can be sequence-oriented all in the same direction, but at different angles. So, for example, all gas diverters can have left gas diverters, but at different angles. The same applies to right-oriented gas diverters. The sequence of orientations of the gas diverters thus affects the attenuation efficiency on the side where the projectile leaves the suppressor and the crack detection at the ejection port, the visibility of flash at the outlet side of the suppressor as well as the heating of the suppressor.

The exit nozzle G has openings or notches (also called releases) G1 that allow passage of gases. On the entry side, when viewed from the passage of the projectile through the core of the suppressor, a tubular extension G3 is provided adjacent to the lastof the gas diverters, the C-type diverter. Inside the extension G3, an inner tubular-shaped extension is parallelly located. Together they share the same wall. Releases for the passage of gases may be engraved at an angle or can be engraved parallel to the axis of the exit nozzle. In the case when releases are incised at an angle, they may be clockwise, or counterclockwise. Threads G2 allowing connection of the exit nozzle with the housing, cross the release notches G1 at a certain angle and depend on the thread step, and on the angle of release G1.

For the projectile to exit the exit nozzle, a bore G4 is provide, which represents the inner wall of the inner extension of the tubular shape and is crossed by the grooves G5 on the outer exit side. The outside of the groove is bounded by the tapered surface G7, as well as semicircular cuttings G6.

The recoil compensator with rotational diversion of gases is shown in figures 5 to 8 and serves for the radial direction of gunpowder gases when they leave the barrel of the weapon. The radial redirection of gases may be clockwise and counterclockwise, or the orientation of radial diversions may differ or alternate in series, depending on the thread intended to attach the suppressor to the weapon barrel. The radial diversion of gases forces gases into rotational motion in the combustion chamber of the suppressor.

The gases passing through diverters J1 get a rotation that conflicts with the gases passing through diverters J2. Due to the different orientations of gas diverters, the torsional forces acting on the offshore compensator are less than they would be if all diverters were oriented in the same direction. The recoil compensator is screwed with a certain force to the barrel of the weapon with a dedicated key J3 of standard size. To do this, inside, at the beginning of the recoil compensator, threads J4 are cut off, corresponding to the threads on the barrel of the weapon.

On the outer starting side behind the hexagon is a round centering surface J7, which serves to align the compensator with the mounting attachment. Behind the centering surface are threads J8, through which the suppressor is connected with the recoil compensator. The threads J8 correspond to the threads in the mounting attachment.

The conical surface J9 serves to align the suppressor with the recoil compensator.

The recoil compensator with a rotational diversion of gases may contain more or less openings J 1 , and J 2 , which are offset at a certain angle from the middle of the projectile bore, but aligned with the barrel of the weapon and the trajectory of the projectile. The openings are offset relative to the axis of the compensator and break at a certain angle J5 in the second part. This forces the gases leaving the barrel of the weapon and the recoil compensator to change direction by bouncing from the front wall of the hole J6 and from the diverters J5. Openings can be divided into several interlocking units, or they can only be a single unit, as shown in Figure 7. One level of openings comprises four openings perpendicular to each other.

The individual openings may be oriented sequentially in different directions and at different angles as shown in Figures 7 and 8. Figure 8 shows a cross-section of other channels and Figure 7 shows a cross-section of the first channels to show the different orientations of the angles of those channels.

The spacing between the recoil compensator and the suppressor core may vary. In some cases, the recoil compensator may touch the suppressor core or be an integral part of it, which is not shown. The core of the suppressor is an inner housing with gas diverters and an exit nozzle.

Some gases are diverted to rotational motion, and the rest of the gases continue their journey through an opening designed for the projectile to travel freely through the recoil compensator. If two consecutive rotary conversions are differently oriented, one of them may be dimensionally larger than the other J1 , J2, or vice versa, or they may be dimensionally identical. Differently oriented gas openings reduce torsional forces transmitted through the compensator to the weapon barrel, or created in the recoil compensator structure.

The opening for the travel of the projectile through the recoil compensator is larger than the projectile passing through and adapted to the caliber of the projectile.

Due to the rotation of the gases in the combustion chamber, they are retained in it for more time, releasing energy and, consequently, speed, due to the interweaving of different rotations of gases. If two rotary units are sequentially differently oriented towards each other, the gases break each other when swirling, losing their power due to loss of speed. The longer they are retained in the combustion chamber, the more time the gases have to burn, cool down, and thus lose their light effect when they leave the suppressor.

The flash hider is used in combination with the suppressor in cases where it is essential for the shooter to minimize the presence of a light signal at the exit of the gun barrel. Primary use is for weapons for military operations or during night hunting, when a powerful flash when a shot disrupts the gunner, or prolongs the spacing between consecutive shots due to the readjustment of the eyes to the dark. In this case, the suppressor is used in combination with the flash hider or vice versa. The flash hider is specially adapted to the suppressor and is part of the patent claim. The flash hider is shown in more detail in Figures 9 to 11.

On the initial entry side, there is a bore on the inside with threads H18, which can have different dimensions, steps, and lengths and match the threads at the weapon barrel. Behind it a bore for the passage of the projectile is provided, the diameter of which is larger than the projectile. On the outside of the entry side of the flash hider, a hexagon of standard dimensions H1 is provided, with which the flash hider is attached to the barrel of the weapon. Behind the hexagon is a round release H2, which is smaller than the hexagon and from the cylindrical surface H3. Behind the release H2 is located the cylindrical surface H3, which serves to align the suppressor with a flash hider in combination with the conical surface H7. The cylindrical surface H3 corresponds to and is slightly smaller than the inner adjacent surface on the mounting attachment E. The round surface H4 represents a relaxation between threads H5 and the center surface H3. Threads H5 achieve a junction between the flash hider and the suppressor. The round surface H6 serves to move away from the inner adjacent tapering surface on the mounting attachment. The surface H8 is cylindrical in shape and is incised from the opposite direction of travel of the projectile with six releases to divert or release gunpowder gases into the environment. Of the six notches, three are larger and longer, and three are smaller and shorter. Longer and larger grooves are marked with the designation H17 and are bounded in width and height by two opposing surfaces H12, bounded in length by the hemispherical surface H11. Between themselves, the H17 notches are shifted 120 degrees around the perimeter. Between notches H17 and H16, there is a setback of 60 degrees. The smaller notches of H16 also follow each other around the perimeter, with a delay of 120. The H16 notches are bounded by two opposite H14 surfaces in width and depth and by the length of the semicircular surface H13. The H16 notches are shorter and smaller than H17 notches due to structural strength

The notches H16 and H17 on the inner wall cross the hole H19 for the passage of the projectile. On the exit, where the notches cross the projectile passage bore, there is a smaller semicircular remnant of the bore H15. The length of notches H16 compared to the notches H17 is at least half its length, in some cases the notches H16 may also be shorter. Gunpowder gases spread through the gun barrel during combustion and, entering the flash hider, continue their journey through the bore H19.

The direction of travel of gases is indicated by an arrow. Part of the gases that first reach the notches H17 begin to be released into the surrounding area. The surrounding area is limited inside the suppressor by a combustion chamber, in front of the inner core of the suppressor when it is attached to the flash hider, otherwise, the gases will be released into the natural environment, where they mix with cooler air and therefore quickly lose heat, as well as the light effect. After traveling along the bore H19 for the passage of the projectile, gunpowder gases are released even more intensively into the surroundings when meeting with three more releases H16, gradually but extremely quickly cooling. The release of gases into the surrounding area is turbulent and forms a small fireball in the immediate vicinity of the flash hider. A fireball is significantly smaller than an elongated light flash, which is formed if a flash hider is not installed on the barrel of the weapon. The smaller light trail is due to the release of gases into the surrounding area, which takes place in two phases. The first phase extends from the beginning of the notches H17, the part where gunpowder gases cross the walls of the flash hider for the first time, to the part where the notches H16 begin. The second phase of gas release into the environment begins from the H16 notches and combines both gas output paths through notches H16 and H17. Most of the gases then exit weakened, beyond the bore H19. The flash hider is thus extremely compact and efficient. The length and width of the flash hider shall be adjusted to the size of the suppressor or attachment E, housing D, and to the length of the inner housing F.

The suppressor divides the gas flow into three different flows, between which two (the second and third) can be mixed. In general, the flows are as follows:

The first gas flow passes from the mounting attachment through the flash hider or the recoil compensator channels, through the combustion chamber, and continues its journey through the channels of the inner housing, leaving through the openings of the inner housing.

A second gas flow passes through the channels of the flash hider or the recoil compensator, through the combustion chamber, and continues along the perimeter of gas diverters. The gases leave the suppressor through the exit nozzle through its perimeter openings.

A third gas flow passes through the channels of the flash hider or the recoil compensator, through the combustion chamber and continues through the conical surfaces of gas diverters and their interior. The gases from this flow can enter another flow through openings in a central part of the gas diverters, or they may leave the suppressor through the central bore of the exit nozzle.

Specifically, the first flow of gases is mostly formed by gases that have left the flash hider or the recoil compensator through lateral openings, losing most of their speed. They are also joined by a part of gases that have left the flash hider or the recoil compensator through the projectile bore. Part of these gases may divert the conical extension F7of the outer surface of the inner housing or, if the conical extension is not used, the first gas reflector with circumferential gas diverters, which is located as the first in a series of gas diverters and is contained as an integral part of the suppressor core in inner housing F, which is cylindrical in shape. The first flow is limited on the outer side by the housing D, and on the inner side by the outer wall of the inner housing F, in which the gas inhibitors and diverters are located, and the braking spiral F4. The inner wall of the first flow is all surfaces that are not part of housing D and which are not the inner cylindrical part of housing F.

On the entry side of the first flow are gas diverters F2a with release F2d, followed by diverters F2b with opposite orientationand releases F2e. Between the diverters F2a and F2b surface F2c is provided, which is designed to rotate gases to slow down and cool them. The gases passing diverters F2a after the release F2d get the right torque, which makes it difficult for them to pass past diverters F2b after the release F2e, forcing gases to the left torque. As a result, the gases begin to rotate around the surface F2c before traveling past diverters F2b.

The gases that have crossed diverters F2b have thus already cooled slightly and slowed down due to rotation around the surface F2c, and are again entering a rotation across the surface F2c, which is interpreted as the second rotating surface for gases. The gases are thus retained on the F2c rotary surface, as they have diverters F2a ahead of them that do not allow them to pass freely due to opposite-oriented diverters or break them slightly.

The last in the plurality of gas diverters is shown in Figure 4, which is the diverter F2a.

When the gases of the first flow cross the last releases in the series of diverters F2a and F2b, they swirl over the release surface F8 and then crash into the braking spiral F4. The brake spiral F4 is designed to prevent the direct flow of gases of the first flow through releases F1. It can be left- or right-oriented, which depends on the orientation of the rear diverters.

In Figure 4, the spiral F4 is counterclockwise, i.e. to the left. It can also be oriented to the right, i.e. clockwise, depending on the braking effect that is sought on the passage of gases. First flow forces gases through releases F1 past the brake spiral F4 and surface F9. Behind the braking spiral and before the releases F1 the cylindrical surface F9 is provided, which allows the gases to swirl and cool along its circumferential side. The longer the gases swirl around it, the more they cool down and the more speed they lose.

The second flow is formed by the gases that have passed the flash hider or the recoil compensator through the projectile bore, as through other grooves and gas release notches, and slides on the conical surface Ab of the first gas deflector, followed by the second conical surface Ac, of the first gas deflector in the series. From the outside, the second flow is bounded by the inner walls of housing F. The gases continue their journey through the releasing Ag past the diverters Ad, where the gases are diverted to rotation around the cylindrical shape Ae. Diverters Bd and Ad may have different angles and different dimensions. Also, the cylindrical surfaces Be and Ae can be of different lengths and different diameters. The gases then continue their journey through the release Bg and bounce off diverters Bd and swirl around the cylindrical surface Be. They are joined by part of the third flow through the release Af and Bf and together they form a second flow. Due to the difference between the angles of the gas diverters Ad and Bd, the gases must change their direction after the Bd diverters have passed in order to cross the Ad diverters. Because of the torque imposed on them by diverters Bd, they swirl around the cylindrical surface Be, cooling and losing speed.

The initial gases that have entered the second flow push the flow of gases until they lose their thrust power. In the case when identical gas diverters are stacked sequentially, the gases do not lose their speed when passing individual gas diverters of the same name or lose less because they are always oriented in the same direction and therefore the swirling of gases is less. The second current in this case is faster. For example, if we sequentially fold all the diverters of gas B, and then gas diverters A, the gases are forced to change the rotational moment between the transition from the last in the row of gas diverters B and the first deflector A, which is in the row of diverters A.

On the circumferential side, the second current is limited by housing F, and from the inside it is bounded by the outer surfaces of gas diverters. The second and third flows are intertwined in some cases. That is, at least one part of the gases from the second flow, returns through the release openings of Bf, or Af, in the diverters of gases to the third flow, and vice versa. If gas diverters of the same name as peripheral gas diverters are all equally oriented, a lower braking effect on the passage of second-flow gases is achieved.

The reverse is achieved by putting together sequentially different named gas diverters. The second flow passes into the surroundings by crossing the release notches G1 on the outlet nozzle G.

To obtain the maximum braking effect of the gases of the second flow, a deflector shall be positioned as the last in the row of gas diverters, which is angularly oriented differently from the angle of release notches G1.

To achieve a lower braking effect, a deflector is positioned as the last in a series of gas diverters, which has circumferential diverters oriented in the same way as oriented release notches G1 on the exit nozzle.

The third flow of gases is formed by gases, which left the bore of the flash hider or the recoil compensator, and have the narrowest orientation and move inside the gas diverters with peripheral gas diverters and pass through semicircular holes Bf and Af, into the second flow, and from the second flow to the third flow. The gases that pass the first bore for the passage of the projectile through the first gas diverter represent the beginning of the third flow. After passing the bore, they crash into the pointed surface Bb or Ab, the next gas deflector, as well as the surface Ah or Bh, depending on the sequence of gas diverters. The portion of gases passing bore Aa or Ba, because of surfaces Ah or Bh forces outside the center of the axis of the gas diverters, as from the direction of travel of the projectile. The portion of gases gliding on the pointed surface Bb, or Ab, and surface Be, or Ac, continues its journey past the semicircular releases Af, or Bf of the previous gas diverter. The pointed surface Bb, Ab is at a sharper angle, like the pointed surface Be, Ac. Some gases are thus diverted via the release Bf or Af into a different flow, and the remaining gases of the third flow are retained in a hollow interior between two gas diverters.

Due to the round release for the passage of the projectile on the next gas deflector, the gases pass into the next hollow interior, which is bounded on one side by the first in a set of gas diverters, and on the other by the second gas diverter in the plurality of gas diverters. As before, the gases slide first on the surface Bb, Ab, then on the surface Be, Ac, and on the tapered surface Ah, Bh.

A part of the gases remain in the space between two gas diverters, and a part of the gases again passes into another flow. The process continues until the gases finaly leave the space between gas diverters through the projectile bore and pass through the outlet nozzle, or through the bore G4, or via the holes Cf of the last gas diverter and then join the second flow exiting through the notches G1.

The examples shown are strictly exemplary and non-limiting illustrations of the possible embodiments of the invention. Within the scope of the invention, as described and defined in the claims, other designs of the suppressor may be possible, which are clear to the technical expert, but this does not limit the essence of the invention as described above and defined in the claims.
