Description

The invention relates to a silencer device with a silencer body with a hollow cylindrical jacket and a first hole near the muzzle of the barrel of a firearm, formed in a first end face, for the entry of a projectile and a second hole opposite the first end face for the exit of a projectile Projectile provided second end face, wherein a plurality of sound reduction bodies are arranged between the first end face and the second end face.

The invention further relates to a drying body for insertion into the opening of a silencer device according to the invention.

Silencer devices of the type mentioned at the outset, designed according to the state of the art, bring about a sometimes significant reduction in the explosive noise that occurs when a firearm is fired, described as a bang.

In this context, it should be noted that when the propellant of a cartridge burns during a shot, acidic gases are created which condense on the inner surfaces of a silencer body and subsequently settle there as a liquid film.

Part of this acidic liquid film regularly runs back into the barrel of a firearm in question and causes corrosion of the inner surface of the barrel, which reduces the firing properties of the firearm.

For this reason, users of firearms equipped with silencers are required to remove and dry the silencer from the weapon after each use, an activity that is often forgotten or omitted due to ignorance.

The known silencer devices therefore all have the disadvantage that, in connection with generally suboptimal handling, a degradation of the firing properties of a firearm in question can be recorded.

The publication DE 10 2020 107 307 A1 discloses a device for drying silencers for weapons, which comprises at least one air flow generating device for generating an air flow through the silencer, wherein the at least one air flow generating device is arranged on or in a first housing which can be arranged in a form-fitting and/or non-positive manner at the mouth of the silencer, wherein the air flow generating device is designed or arranged or aligned on the first housing in such a way that the air flow generated by the air flow generating device is designed or arranged or aligned on the first housing in such a way that the air flow generated by the air flow generating device is directed out of the silencer in the projectile direction.
