Description

The description relates to a silencer for long and short weapons according to the preamble of the utility model claim.

According to the state of the art, mufflers for firearms generally consist of a tube which serves as an expansion space for the muzzle gases and for accommodating gas pressure reflection elements of very different shapes, which are arranged perpendicularly or axially to the firing channel and serve to dampen the firing.

Silencers of this construction are complex to manufacture and very difficult to maintain. Moreover, it is not possible without much effort to adapt these constructions to the individual sound characteristics of a weapon. Another disadvantage is then that due to the design of these silencers usually not flexible enough material and structure can be adapted to different weapons.

Frequently, mufflers, in particular for firearms, known which can be mounted on the barrel or muzzle fire dampers of firearms and surrounded by a lying eccentrically to the central longitudinal axis cylinder jacket, which is divided by transverse walls of the cylinder jacket into individual chambers, from the mouth of the Remove the weapon to the mouth of the silencer. The peculiarity of this embodiment is that the pipe run of the damper according to two mutually parallel planes, which in turn is parallel to an imaginary plane defined by the soul axis and are cut so that at the marked by a circular cross-sectional image of the barrel two each other opposite lying circular sections are missing, the height of which is dimensioned so large that the cutting planes in the tube soul come out longitudinally slot-like. These measures led to an already very well-reduced sound attenuation, but this does not seem sufficient for today's purposes and is often very expensive to manufacture.

The object of our example is, on the one hand, to avoid the above-mentioned disadvantages and, on the other hand, to use more efficient physical principles to create a muffler that is easy and inexpensive to manufacture and a great variability in terms of the frequencies to be damped Recording of the resulting explosion gases and the adaptation of the material based on the resulting explosion pressures has.

The solution of the problem is based on the directly surrounding the firing channel tube (hereinafter called chamber part) which contains holes, which together with the surrounding damping tube (cladding tube) form the resonator. The frequency ranges to be damped are determined by the spacing of the bores from one another and by the diameter of the individual bores in conjunction with the wall thickness of the chamber part and the volume of the surrounding damping tube.

By number of holes and their specific shape, as well as the length of the chamber part, the muffler can be tuned over wide frequency ranges. A further frequency adjustment can be achieved by reducing or increasing the wall thickness of the chamber part in the region of one or more holes.

Other specially formed under flow aspects of openings on the baffles of the chamber part serve to redirect the explosive gases in the holes provided with the nearest chambers of the chamber part and there to expand and cool, slow down and swirl, so as to dampen the explosion bang as much as possible. Between the chamber part and the outer shell, an insulation for improving the damping properties can be introduced. The material of the insulation is selected depending on the resulting temperatures and pressures.

The outer tube (shell) is provided on the side facing the weapon with a thread on which a device for attachment of the muffler to the corresponding weapon can be applied (connector unit). This device is not only used for fastening purposes, but contains a further device which compensates the gas pressure to the necessary recoil impulse during reloading of, for example, semi-automatic firearms to deliver it as impulse towards the muzzle.

The chamber part is chosen so that it can consist of either one or more separate pieces.

The number and shape of the holes, as well as the length of the overall construction are determined depending on the acoustic, mechanical and thermodynamic requirements that arise individually by the respective weapon.

These and other features of possible refinements of the muffler go out of the claims and from the description and the drawings, the individual features are realized in each case alone or more in the form of sub-combinations in the embodiment of the muffler and other fields and can represent advantageous and protectable versions for which protection is claimed here.

The muffler will be explained below with reference to the figure.
