Definitions

  • the invention relates to a silencer according to the preamble of claim 1, as known from FR-A-684 938 (VERGNE).
  • This known silencer consists of an attachable to the muzzle of a weapon, an end piece and in between a series of centering rings that form the outer wall of the muffler and between which a partition is inserted with a through-opening to form successive chambers.
  • the length of the individual rings differs from one another, so that each length section of the muffler is assigned only a single, special ring.
  • front and back or front and back refer to the weft direction, the front facing the weft direction and the back facing the weft direction.
  • a muffler in use today is known from DE 17 03 420 B1 or the corresponding US Pat. No. 3,385,164 (WALTHER).
  • Its center piece has a cylindrical cladding tube, on the back of which the extension piece and on the front of the end piece are attached.
  • the extension piece can be screwed gas-tight onto an external thread attached to the barrel of a rifle.
  • the cladding tube there are, in addition to other elements, several successive, mutually supported chamber parts, each one against the inner wall of the cladding tube have a longitudinal sleeve and a cross bar.
  • the crossbar extends generally across the longitudinal sleeve and thus across the longitudinal axis of the muffler. In the middle it has a penetration opening, from which it widens in steps.
  • the chamber parts are centered via the cladding tube.
  • each chamber part reduces the muzzle bang by around 4 db - provided that only a limited number of chamber parts are used.
  • a silencer should always be as short as possible. It increases the length of the firearm, which is laboriously shortened by other constructive means, and also leads to a weighting of the muzzle, which affects the balance of the weapon.
  • the invention has for its object to further develop the known silencer mentioned at the outset so that it can be adapted to the respective requirements with little effort.
  • the invention solves this problem with the subject matter of claim 1, that is, an object in which the generic features are linked to the further features that each chamber part is attached directly to the adjacent chamber part according to the modular principle and the outer walls of the successive chamber parts form the silencer outer wall.
  • the cladding tube directly delimits the expansion chamber. It must therefore have a strength and therefore a wall thickness that can withstand the gas pressure that arises.
  • the longitudinal sleeves of the known chamber parts essentially serve as spacer sleeves. This increases the weight of the muffler considerably, which is disadvantageous for the reasons already mentioned. All of these disadvantages are eliminated in the subject of the invention, since the cladding tube is eliminated.
  • the muffler according to the invention stands out not only because of its lower weight, but also because of its lower manufacturing costs from the known mufflers.
  • the cladding tube Since the cladding tube is omitted, it can no longer determine the length of the silencer. Rather, this can each be composed of a number of suitable chamber parts of your choice so that it is optimized according to the respective area of application, such as barrel length, type of cartridge and the desired damping effect. For this purpose, only a sufficient number of chamber parts of the respective training have to be produced, which is possible simply and inexpensively, for example by die casting, but especially in automatic lathes. During assembly, a wide variety of silencers can then be manufactured using a modular system by suitably combining the chamber parts.
  • Muzzle attachments of this type serve to significantly improve the trajectory of the swirlless projectiles, for example projectiles of a mortar, ballistically. They are not silencers.
  • Such muzzle attachments usually have no cladding tube.
  • the known muzzle attachment consists of a stack of approximately disk-shaped ring disks. Spacers are arranged between the individual washers. The entire stack is held together by many tie rods. The muzzle gases can escape directly between the washers over the entire length of the muzzle attachment.
  • a similar arrangement is also known from AT-39 274 (LOTH), which relates to a silencer.
  • This muffler also has individual chambers which are held together by tie rods in a similar manner to the case with the above-mentioned mufflers by means of a cladding tube.
  • the individual chamber parts can be connected to one another, to the extension piece and / or the end piece, for example by resistance welding. With this type of connection, parts with a non-circular cross-section can also be attached to each other.
  • each chamber part has a circumferential thread at its front end and a circumferential thread complementary to this at its rear end, for example and preferably a nut thread at its front end and a father thread at its rear end.
  • the end piece and the end piece are each fitted with a male or female thread.
  • the threaded connections of the individual elements enable the silencer to be dismantled easily, for example for cleaning purposes.
  • this also involves dangers: Fine threads can be damaged by improper or insufficient screwing, which also applies to the silencer elements when using unsuitable tools.
  • all threaded connections, but at least those of the chamber parts to one another, are fixed in a practically non-detachable manner after assembly, for example by flanging or punching the circumferential joints.
  • a relatively soft, easily machinable material for the chamber parts possibly also for the other elements of the silencer, in which multiple screwing and unscrewing without damage the thread would hardly be possible. Any necessary cleaning can be done by rinsing. (Claim 6).
  • the chamber parts preferably consist of an easily machinable aluminum alloy, as does the end piece.
  • the attachment which often has to be screwed onto the pipe mouth of the firearm to be equipped with the silencer and has to be unscrewed from it again, can consist of a material that can be subjected to higher loads.
  • each chamber part is essentially formed by a longitudinal sleeve, in the free end portions of which the complementary circumferential threads are arranged.
  • the longitudinal sleeves are preferably designed as circular cylindrical sleeves. Such a configuration of the chamber parts enables a particularly simple assembly of the silencer.
  • the successive outer walls of the longitudinal sleeves together form the outer wall of the muffler (claim 7).
  • a transverse web arranged in the interior of the chamber parts and widening in a funnel shape promotes sound absorption in a known manner (claim 8).
  • the crossbar can be arranged at that end of the chamber part or the longitudinal sleeve which carries the male thread.
  • the crossbar is arranged in a central region of the outer wall part of the chamber, ie the longitudinal sleeve, that is to say in a region which is not occupied by the threads.
  • a tensioning tool can be attached to this area when assembling the silencer, the attack of which is then supported by the crossbar.
  • This in turn enables one thin-walled design of the outer chamber wall, ie the longitudinal sleeve, without having to fear problems during assembly.
  • the crossbar is integrally connected to the longitudinal sleeve (claim 9).
  • the penetration opening in each crosspiece should be as small as possible in order to form the narrowest possible throttling point for incoming powder gases after passing through the projectile.
  • direct rubbing of the projectile is avoided by appropriate dimensioning of the bullet opening, a very high erosion occurs there.
  • the penetration opening can widen and thus reduce the sound absorption.
  • the penetration opening is covered with a bushing, which can consist of a more resistant material than the chamber part, for example made of steel (claim 10).
  • the effectiveness of the muffler according to the invention is further increased by the fact that the end piece and / or the extension piece have an additional relaxation chamber, especially since they have a corresponding length anyway if they are provided with a male or female thread.
  • the relaxation chamber formed in the end piece is preferably designed as a diaphragm body which dampens the muzzle flash (claims 11 and 12).
  • chamber parts of a muffler are preferably identical to one another. This is a mix-up when assembling excluded and at the same time achieved a particularly simple manufacture.
  • the silencer shown is intended for the G3 rifle manufactured by the applicant. Its overall length is 255 mm, its largest outside diameter is 40 mm and its overhang over the muzzle of the G3 rifle is 152 mm.
  • the silencer consists of three main parts, namely an extension piece 2, a middle part 4 and an end piece 6.
  • the extension piece 2 consists of an elongated tube, preferably made of aluminum, on the front in a cup-like manner, and has, from back to front, in succession: a tube section 8, a narrowed cylindrical fitting section 10, a threaded section with an internal thread 12, one radially following one another internally extending stop shoulder 14, a passage 16, the diameter of which only slightly exceeds that of a projectile from the rifle (not shown), a chamber 18 which widens conically towards the front and a greatly enlarged cup section 20 with a fine nut 22.
  • the extension 2 is screwed (after unscrewing the muzzle fire damper from the tube mouth of a rifle G3) with its internal thread 12 onto the tube mouth.
  • the fitting section 10 slides tightly onto a complementary fitting section of the pipe mouth, and the end face of the pipe mouth lies against the stop shoulder 14.
  • the stop heel 14, the internal thread 12 and the fitting section 10 thus center the extension 2 exactly on the pipe mouth.
  • the middle part 4 is composed of several, here four screwed together chamber parts 24. One of these chamber parts 24 is described below.
  • Each chamber part 24 consists of a heat-resistant aluminum alloy and has an overall circular cylindrical, tubular longitudinal sleeve 26 with an overall smooth, circular cylindrical inner wall and outer wall 28.
  • the front end of the longitudinal sleeve 26 is turned out and provided with a nut fine thread 30, which corresponds in length and other dimensions to the nut thread 22 in the cup section 20 of the extension piece 2.
  • the rear end of the longitudinal sleeve 26 carries a male fine thread 32, which is designed to be complementary in length and dimension to the female fine threads 22 and 30.
  • a crosspiece 34 fills the clear width of the longitudinal sleeve 26. It has the shape of a funnel which is concentric with the longitudinal sleeve 26 and widens towards the front, the edge of which is integrally connected to the inner wall of the longitudinal sleeve 26 in the area between the two fine thread ends 30 and 32.
  • the forward-facing inner wall of the funnel-shaped crosspiece 34 does not form a continuous frustoconical surface, but is composed of a radially inner rear frustoconical surface and a radially outer front frustoconical surface offset therefrom.
  • the inner truncated cone surface has a smaller apex angle and merges into the outer truncated cone surface. This design of the chamber part 24 increases the damping effect.
  • the constriction of the funnel 34 thus formed lies with the rear end of the longitudinal sleeve 26 approximately in a radial plane.
  • a tight-fitting sleeve 36 made of sheet steel is pressed into it and knocked backwards and radially outwards around the rear end of the constriction.
  • the steel bushing 36 is thus non-detachably and firmly connected to the funnel constriction and lines it.
  • the clear width of the steel bushing 36 is dimensioned such that, taking into account all the tolerances that occur, it can just pass the projectile without it rubbing against it.
  • the mouth of the chamber 18 of the extension piece 2 which widens towards the front, is arranged and dimensioned such that there is a relatively narrow annular gap to the rear outer peripheral edge of the steel bushing 36 or the transverse web 34 of the rearmost chamber part 22.
  • the annular gap leads into a first expansion chamber, which is delimited by the following parts: the rear of the transverse web 34 and the rear part of the longitudinal sleeve 26 of the rearmost chamber part 24 and the bottom of the cup-like extension 20 of the extension piece 2.
  • the end piece 6 is an essentially cup-shaped body with a short pipe socket 38, one end of which is closed by an outwardly curved end wall 40.
  • a committee opening 42 passes through the middle of the end wall 40. The inner edge of the committee opening 42 is strongly countersunk.
  • the outside of the pipe socket 38 carries a male thread 44, the dimensions of which correspond to the male threads 32 of the chamber parts 24.
  • the inside of the pipe socket 38 carries an internal thread 46, into which a diaphragm body 48 serving to muzzle fire or flame damping is screwed.
  • the diaphragm body 48 has a threaded ring 50, the rear end of which is closed by a radial plate 52.
  • the radial plate 52 is penetrated centrally by a bullet hole. Its peripheral edge extends to the inner surface of the adjacent longitudinal sleeve.
  • the panel body 48 can be made from an easily machinable aluminum alloy, but preferably from a more resistant material.
  • the bullet hole can be lined with a sheet steel sleeve similar to the sleeves 36.
  • the diaphragm body 48 and the end wall 40 of the end piece 6 delimit a foremost, last expansion space 49.
  • the rear tubular end of the extension 2 can be held, for example, in a collet.
  • the threads 16, 30, 32, 44 and 46 are preferably either filled with a heat-resistant putty or adhesive before screwing or caulked after tightening or otherwise secured so that the fully assembled silencer can no longer be dismantled.
