Description

Compensator for a firearm

The invention relates to a compensator for a firearm.

Known firearms are capable of targets up to 1500 meters away

penetrate. Due to the high power required for it, however, also correspondingly high recoil and high impact forces. In general, compensators attached to the firearm usually at the end of the weapon barrel can be used to redirect the gas flow emerging together with the projectile under high pressure during a shot of the firearm in such a way that the recoil and / or the recoil of the weapon is reduced as much as possible. The reduction of the recoil or the high blow is particularly advantageous because the subsequent shot can be easily placed in the target when the target targeted at the first shot less from the field of view of the shooter, especially when using riflescopes passes. The orientation of the shooter found before and during the delivery of the first shot should thus be preserved as far as possible after the firing or be disturbed less by the high blow or recoil of the firearm.

From DE 199 61 688 B4 a compensator of the type mentioned is known. The disclosed there compensator is a solid cylindrical member with a passage bore for a projectile and with two transverse to its longitudinal axis, on the side of the barrel down and horizontally arranged through slots and also with baffles in two chambers, which incorporated perpendicular to the longitudinal axis in the component are and start below the through hole and are open at the top. The chambers are according to DE 199 61 688 B4 to Hochschlagkompensation provided while the slots are provided with the baffles for recoil compensation.

From DE 38 31 766 C2 a Hochschlagkompensator is known, which has obliquely incorporated slots and also oblique baffles.

From US 7,748,306 Bl a compensator for firearms with three upper openings is also known. These openings are in a stepped manner forward, i. arranged in the weft direction tapered longitudinal axis sections.

An object of the invention may be to equip a compensator such that the recoil and the high blow is even better compensated.

To solve the problem, a compensator according to claim 1 is proposed. In the dependent claims advantageous embodiments of the compensator are proposed.

In a first embodiment, a compensator for a firearm, comprising

- A first, extending in the direction of the longitudinal axis of the compensator

Passage opening for a projectile,

- A second, transverse to the longitudinal axis extending, horizontally continuous

Through opening to a first expansion chamber in a first

Form compensator section,

- A baffle, which limits the second passage opening forward in the weft direction, wherein the baffle is inclined to the vertical of the longitudinal axis by a positive impact angle forward.

It has surprisingly been found that the gas pressure that is released when leaving the gun barrel through the projectile, also alone of a both sides open and up and down closed passage opening in conjunction with the said oblique baffle can be redirected so that both the recoil and the high impact can be reduced.

In a further development of the embodiment, the expansion chamber in its rear portion on a projecting element for the projectile passage, the diameter of which is reduced compared to an outer diameter of the Kompensatorabschnitts which forms the passage opening. The projection element is preferably formed symmetrically to the longitudinal axis of the compensator. In one embodiment, the projection element may be two plane, parallel to

Form longitudinal axis and perpendicular extending side surfaces, and be provided for example as a pin with a rectangular or square base.

In particular, the projection element can form a planar top side and underside extending parallel to the longitudinal axis and horizontally. . In the projection element is always provided a bore for the projectile passage. An end face of the projection element forms a clearance to the oblique

Prallfiäche. By equipping the expansion chamber with the projection element, both the recoil and the high impact can be further reduced. The projection element acts here as a pressure transmitter in the weft direction.

Surprisingly, it has been shown that particularly low impact angle of

Impact surface can contribute to an excellent reduction of recoil and high blow of the firearm. Good and very good results are achieved even with a baffle angle of the baffle in a range between 0.1 and 2 degrees, preferably between 0.2 and 1.5 degrees, preferably 0.4 and 1 degrees and in particular 0.5 degrees.

As a particularly advantageous embodiment, a further development of the compensator described above is proposed by a third, transverse to the longitudinal axis extending, horizontally through passage opening, a second expansion chamber in a second Kompensatorabschnitt forms. The second expansion chamber also has a baffle surface which delimits the third passage opening in the weft direction to the front, wherein the second baffle surface is inclined to the vertical of the longitudinal axis by a positive baffle angle forward.

A further embodiment further provides that the second expansion chamber has in its rear portion a second projecting element for the projectile passage, whose diameter is reduced compared to an outer diameter of the second Kompensatorabschnitts.

The projection element in the second expansion chamber preferably forms two planar lateral surfaces extending parallel to the longitudinal axis and perpendicular and can also form a planar top side and underside extending parallel to the longitudinal axis and horizontally and thus also be pin-shaped. The projection element is selected from the group of cylindrical pins, rectangular pin and web.

As a preferred baffle angle of the baffle of the second expansion chamber, a value in a range between 0.1 and 2 degrees, preferably between 0.2 and 1.5 degrees, preferably 0.4 and 1 degree and in particular 0.5 degrees.

By the proposed two preferably inclined by 0.5 degrees baffles and the two projection elements results in a surprising special synergy effect, in which the result of the efficiency of the

Pressure redirection can be significantly improved. Empirical estimates show up to more than 25 percent higher efficiencies than comparable compensators, depending on the gas flow rate and gas flow rate. In particular, has carried out in specially conducted experiments with a caliber

.338LM, it can be shown that a large part of the pressure can be transmitted from the rearward expansion chamber in the weft direction to the weftwise frontward expansion chamber. In one embodiment, the outer diameter of the first compensator blank is greater than the outer diameter of the second compensator blank, and the first compensator blank is formed in the weft direction past the second compensator blank. Accordingly, the expansion chamber of the first

Kompensatorabschmtts in its volume to be greater than the expansion chamber of the second Kompensatorabschmtts.
