Definitions

  • the utility model is related to a rifled firearm suppressor, a.k.a. a silencer, to be mounted in the front section of the rifled firearm barrel and intended to reduce the harmful effects of the gases upon having the bullet exiting/leaving from the muzzle section, thus achieving reduction of noise and recoil when firing
  • the suppressor is mounted to the firearm by a threaded connection between a threaded sector, made along the ban-el of the firearm, and an internal thread made in a fixedly mounted in a steel sleeve centrally located in the suppressor core, providing connection between the aforesaid elements.
  • a suppressor is known produced by Recknagel (Product catalog - March 2019), and it consists of a cylindrical metal housing, and its interior space houses a core with a disk-shaped partition system of elements and openings made along the outer surface on the core.
  • a fixed connection sleeve is mounted inside the core, with a connecting thread made along its inside surface to attach the firearm barrel of the specified size.
  • This noise silencer joins the barrel by a threaded coupling between the said sleeve and an outer thread formed along the barrel.
  • a disadvantage of the construction described is the fact the suppressor is of limited application due to the fact it can only be mounted on a specific thread size of a firearm barrel.
  • Patent Publication EP1255959 B1 is known and it describes a suppressor mounted on the barrel of the firearm by means of a threaded connection internally formed on the core of the suppressor.
  • the device consists of an external casing where the core is located in, and radially shaped disk elements on it forming the working chambers.
  • the core and disk elements are formed as a single body, with gas openings (as shown in Figure 6) arranged radially along the core, located only in the working chambers in front of the muzzle cut.
  • a threaded sector expansion is formed to connect the core to the casing.
  • an internal thread is formed in the rear section of an orifice made in the core by which the suppressor is fixedly mounted to the barrel of the firearm.
  • a disadvantage of the known technical solution is the insufficiently effective action.
  • the core with the disk elements and gas openings is structurally constructed in such a way that by having this positioning of the suppressor relative to the barrel of the firearm, while firing the operation chambers 1, 3, and 4 the main bulk of the released gases pass through are many times more loaded by the operation chambers 2 and 5, as the latter have a much smaller proportion of released gases, and it results in the following: the provided rear chambers (2 and 5) are not effective enough in regards to reducing the pressure of the gases.
  • the aim of the utility model is to offer a suppressor of an increased resource of use, to provide a significant reduction of noise and recoil by the fired gases, allowing high firing rate while maintaining efficiency as well as its use with ammunition of increased /magnum/ charge.
  • Another aim of the utility model is to have the suppressor distinguished for its efficiency in regards to its versatile use in various sizes of firearm barrels.
  • a suppressor consisting of a cylindrical casing, where a stem with radially disposed disk elements is arranged in, having a number of gas openings made along the stem, where the openings in a row are shifted in relation to the openings in another row, and an internal thread is made/placed inside the stem.
  • the suppressor consists of a rear discharge (unloading) chamber, formed by rear and front extension along the stem, on which a fixed a rear casing (housing)is mounted and a front extension chamber, formed by the rear and front extension, to which a fixed front casing is mounted, wherein the discharge and extension chambers are separated from each other by a dividing channel, and in the rear discharge chamber, inside the stem there is a removable connecting sleeve attached to the firearm barrel, as externally along the stem, radially arranged gas openings are located whereby along the front extension of the discharge chamber, at least two outlet openings are symmetrically aligned axially to the axis of the suppressor, and in the rear extension of the discharge chamber, a threaded section is formed - and at least two openings are formed along it whereby the inside wall of the rear extension, a groove is formed with a slotted ring in it and at the front extnsion chamber of the suppressor have at least two disk elements.
  • outlets in the front extension of the discharge chamber are oriented at an acute angle to the axis of the stem.
  • the replaceable connecting sleeve is made with an internal thread corresponding to the thread of the respective barrel, and two thread sections are formed along its outer surface, separated by a locking channel.
  • a fixing orifice is formed on its outer surface, the location of which coincides with the fixing groove of the replaceable connecting sleeve.
  • At least two fixing orifices oriented at 900 toward each other are formed on its outer surface, the location of which coincides with the fixing groove of the replaceable connecting sleeve.
  • an extension is formed whose size corresponds to the size of the suppressor casing, wherein a groove with a slotted ring in it is formed in the inner diameter of the extension.
  • the slotted ring is made of Teflon.
  • the suppressor is characterized by a simple and technically and technologically efficient construction.
  • the proposed suppressor allows the same product to be used in firearms of different barrel diameters and connecting thread sizes. This is achieved thanks to a properly shaped replaceable sleeve, guaranteed to be fixed to the stem of the suppressor, and it can be carried out easily and quickly; no special qualification is required for the mounting (installation) and disassembly works on the sleeve replacement.
  • the improved efficiency of the noise silencer is expressed mainly due to the rapid release of a large part of the gases discharged during firing — it is carried out through the outlets formed at the forehead of the front expansion of the rear discharge chamber, when gases are released directly into the atmosphere before the bullet leaves the suppressor.
  • the accelerated discharge of part of the gases through the discharge openings of the discharge chamber extends the life of the suppressor and allows its use at high firing rates without compromising the effectiveness of the suppressor in reducing noise and recoil of the firearm.
  • Another advantage of the proposed suppressor is the following: gases of highly reduced pressure pass through the suppressor's front expansion chamber, and it practically permits effective noise suppression, while dramatically reducing the load on the disk elements and the casing - resulting from the reduced pressure of the passing gases.
  • Fig. 1 A general view of the suppressor according to the utility model, with a halfsection of the stem and the replaceable sleeve Fig. 2 A cross-sectional view of the suppressor of A-A from fig. 1
  • FIG. 3 An axonometric view of a removable connection sleeve according to the utility model
  • FIG. 4 A cross-sectional view along the B-B from fig. 1
  • Fig. 5 An axonometric view of a slotted ring located in the channel of the extension of the rear extension of the discharge chamber.
  • the description further provides an exemplary embodiment of a suppressor according to the utility model, characterized by a technological construction providing improved noise reduction functionalities when using a firearm, and an exemplary embodiment is provided suitable for use with hunting weapons and it does not restrict their use in other firearms, as well as the use of barriers and openings adapted in regards to their placement and design, in a way that provides an equivalent effect in suppressing noise accompanying the movement of gases when discharged from the barrel of a firearm.
  • the present utility model can be understood in more details by reference to the accompanying drawings, description, examples and claims.
  • the suppressor consists of a front casing 2, respectively a rear casing 1, separated by a dividing groove 3.
  • a stem 4 is located inside, and each of the said casings 1 and 2 is secured to the stem 4 by expansions (5 and 6, located at both ends of the rear discharge chamber 11 and extensions 7 and 8 located at both ends of the front extension chamber 12 formed in the volume of the suppressor closed between the casings 1 and 2, the stem 4 and their closing extensions 5, 6, 7 and 8.
  • the front section of the discharge chamber 11 includes the rear section of the stem 4, wherein a removable connecting sleeve 16 is mounted in the inner opening of the stem 4.
  • the sleeve 16 is made with an internal thread corresponding to the barrel thread of the firearm.
  • two threaded sections 17, separated by a groove 18, are made.
  • a threaded opening 14 is formed and it is adapted for winding of fixing elements, such as locking screws 20.
  • the threaded openings are at least two and are oriented at 90° towards each other, and their location coincides with the fixing groove 18 of the removable connecting sleeve 16.
  • the effectiveness of the direct discharge of gases through the openings 110 is greatly improved when the said injection openings (10) are oriented at an angle of 20° to 80° degrees with respect to the central axis of the suppressor, preferably at an angle of 60° degrees.
  • the extension chamber 12 includes a system of consequently located disk elements 13 along the stem 4 and the gas outlets 9. [0032] A groove 22 is formed along the inner diameter of the extension 5, oriented against the threaded openings 15, and a slotted ring 23 is located in it. Locking screws 21 are wound in the threaded openings 15.
  • the suppressor is mounted and used as follows: Unwind the casing 1, as it provides access to the elements of the unloading chamber 11. Wind the replaceable connecting sleeve 16 to the stem 4 until it stops, and then the sleeve 16 is fixed to the stem 4 by tightening the fixing screws 20. The stem 4 is wound on the barrel of the firearm and the screws 21 are wound one after another so that the slotted ring 23 rests on the barrel. The casing 1 is then wound to a full stop at the threads of the extensions 5, and the suppressor is ready for use.
  • the remaining gases enter the extension chamber 12 under severely reduced pressure, passing through the gas outlets/vents 9 in between the disk elements 13, and are then released into the atmosphere through the central opening of the suppressor.
  • the suppressor may be used on another weapon of a different connecting thread and/or outer diameter of the barrel, and the mounting operations described above are carried out in reverse order; the connecting sleeve 16 is dismounted from its fixed position by unscrewing the fixing screws 20, and then the mounting groove 19 is unscrewed, taken out and another attachment connecting sleeve - whose internal thread corresponds to the outer thread on the barrel of the firearm - is mounted.
