SUPPRESSOR

Abstract

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. It consists of a rear discharge chamber 11 and a front extension chamber 12; the two chambers 11 and 12 are separated from each other by a dividing groove 3, while inside the core 4 there is a removable connecting sleeve 16 located/mounted to connect to the barrel of the firearm. Also, at least two outlet openings 10 are created symmetrically axially with respect to the axis of the suppressor at the forehead of the front section of the discharge chamber 11.

PRIMARY EMBODIMENT OF THE INVENTION

[0032] 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.

[0033] The present utility model can be understood in more details by reference to the accompanying drawings, description, examples and claims. The above should not be construed as limiting to the exemplary embodiment described, with its specific constructive elements, insofar as variations of the embodiment can be made, retaining the idea of universal use of the suppressor in various firearms by fast and easily changing the connecting sleeve.

[0034] According to the utility model, the suppressor consists of a front casing 2, respectively a rear casing 1, separated by a dividing groove 3. Along the two casings 1 and 2, 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.

[0035] 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. Along the outer surface of the sleeve 16, two threaded sections 17, separated by a groove 18, are made. Along the outer surface of the stem 4 a threaded opening 14 is formed and it is adapted for winding of fixing elements, such as locking screws 20. According to a preferred embodiment, 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. In the forefront, in the rear section of the removable sleeve 16, a mounting groove 19 is fitted.

[0036] In the area of the stem 4, after the point of connection of the suppressor to the firearm barrel, gas outlets 9 are formed shifted to each other. At the front extension 6 of the discharge chamber 11, at least two discharge (injection) openings 10 are formed. According to a preferred embodiment of the discharge chamber 11, three discharge outlets 10 of a diameter of 0.5 to 5 mm are located and arranged symmetrically along the diameter of the expansion (6).

[0037] The effectiveness of the direct discharge of gases through the openings 10 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.

[0038] The extension chamber 12 includes a system of consequently located disk elements 13 along the stem 4 and the gas outlets 9.

[0039] 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.

[0040] 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.

[0041] When firing, after a bullet leaves the barrel, the gases discharged therefrom pass through the gas openings 9, whereby a portion of these gases is released through the outlet openings 10 directly into the atmosphere.

[0042] 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.

[0043] If necessary, 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.

[0044] The description should also be understood in such a way that the terminology used herein is solely for the purpose of describing specific aspects of the description and cannot be limiting in this respect. The described exemplary embodiment allows for the best currently preferred embodiment.

[0045] Specialists in the reviewed technical field will recognize and appreciate various design changes can be made similar to those described herein while still benefiting from the level of noise reduction produced by the gases released by the explosive after firing.
