Abstract

A silencer for mounting on a gun barrel has a silencer housing for at least partially completely enclosing the gun barrel. A jacket pipe is integrated in the silencer housing for encasing the gun barrel. A muzzle brake is formed to hold the jacket pipe in a centered manner in the silencer housing. The silencer also includes at least one device for deflecting and/or cooling a gas that is produced when a shot is fired. A clamping device is provided for form-fitting and/or force-fitting fixing to the gun barrel.

Description

BRIEF DESCRIPTION OF THE FIGURE

(1) The sole FIGURE of the drawing is a longitudinal section through a silencer mounted on a gun barrel.

DETAILED DESCRIPTION OF THE INVENTION

(2) Referring now to the FIGURE of the drawing in detail, there is shown a perspective sectional view of a silencer 2, which is mounted on the muzzle side of a gun barrel 4 of a gun. The gun, by way of example, is a hunting rifle. In this exemplary embodiment, the gun barrel 4 does not have a muzzle thread. In other words, the gun barrel 4 is formed without a thread.

(3) The silencer 2 is designed in particular as an integral silencer and has a cylindrical or tubular silencer housing 6 forming an outer jacket pipe, which completely encloses the gun barrel 4 in sections. The silencer housing 6 receives an (inner) jacket pipe 8, which coaxially encloses the gun barrel 4. On the one hand, the jacket pipe 8 is held in a centered manner in the silencer housing 6 by means of a muzzle brake 10. On the other hand, the jacket pipe 8 is seated in a receptacle of an annular housing cover 12, which closes the silencer housing 6 at one end face.

(4) The muzzle brake 10 engages at least in sections in the jacket pipe 8, wherein a centering sleeve 14 is arranged in the engaging region of the muzzle brake 10, by means of which the gun barrel 4 is center-aligned on the muzzle side in the jacket pipe 8 or respectively in the silencer housing 6. In this case, the muzzle brake 10 is provided in the engaging region with an external thread, which is screwed into a corresponding internal thread of the jacket pipe 8.

(5) The housing cover 12 has a threaded bore on the outside of the housing, into which a clamping device 16, which is designed as a collet chuck, is screwed. For this purpose, the clamping device 16 has a fastening section provided with an external thread 34, which is screwed into the internal thread of the threaded hole. In the assembled state, the clamping device 16 fixes the silencer 2 in a form-fitting manner (i.e., positive fit) and/or force-fitting manner (i.e., friction fit) to the gun barrel 4.

(6) The clamping device 16 has four axially distributed seals 18, which are arranged as radial ring seals on one of the clamping devices 16 surrounding or enclosing the gun barrel 4. In the assembled state, the clamping device 16—and thus the silencer 2—is sealed, in particular gas-tight, with respect to the outer circumference of the gun barrel 4 by means of the seals 18. On the one hand, the seals 18 absorb the forces of the gas pressure of the combustion gases and, on the other hand, the clamping or chucking action of the clamping device 16 or respectively of the collet chuck. The seals 18 further increase the frictional resistance and thus the force-fitting holding force on the gun barrel 4.

(7) The terms “axial” and “axial direction” here and in the following are understood to mean in particular a direction parallel (coaxial) to the gun barrel 4, i.e., perpendicular to the end faces of the silencer 2. Correspondingly, the terms “radial” and “radial direction” here and in the following are understood in particular as a direction oriented perpendicularly (transversely) to the longitudinal axis of the gun barrel 4 along a radius of the gun barrel 4 or respectively of the silencer 2. The terms “tangential” and “tangential direction” here and in the following are understood to mean in particular a direction along the circumference of the silencer 2 or the gun barrel 4 (circumferential direction, azimuthal direction), i.e., a direction perpendicular or orthogonal to the axial direction and to the radial direction.

(8) The FIGURE further shows a projectile 20 discharged from the gun barrel 4, which is shown in the region of a device 22 for deflecting and/or cooling a (propulsion/combustion) gas produced during a firing operation. In this case, the device 22, which is referred to as a gas deflector 22, has a baffle chamber 24 and a gas rotation chamber 26, which are connected axially in succession to the muzzle brake 10.

(9) The baffle chamber 24 has, for example, two baffle walls 28 arranged one behind the other. The baffle walls 28 are each configured, for example, as a conical jacket of a cone, and have, for example, an opening angle of about 45°.

(10) A substantially hollow cylindrical gas rotation insert 30 is received in the gas rotation chamber 26.

(11) The gas rotation insert 30 preferably has a shape or geometry that realizes a particularly high damping performance in as compact an installation space as possible. The gas rotation insert 30 is in particular manufactured as an exchangeable 3D printed part.

(12) Between the silencer housing 6 and the jacket pipe 8, an intermediate space (annular space), which is not described in more detail, is formed as an expansion chamber. In this case, the silencer housing 6 has at least one vent hole 32, which passes approximately radially through the silencer housing 6 and thus couples the expansion chamber or respectively the intermediate space to the environment. Through the vent hole 32, a cold air can escape from the expansion chamber, so that the hot (combustion/propulsion) gases can spread faster and be cooled down.

(13) The silencer 2 can preferably be completely disassembled manually and can be assembled by a user without danger.

(14) The invention is not limited to the embodiments described above. Rather, other variants of the invention may also be derived therefrom by the expert without digressing from the objects of the invention. It will furthermore be understood that all individual features described in connection with the exemplary embodiment can also be combined with each other in other ways without leaving the object of the invention.
