Abstract

Fremgangsmåte og innretning for å redusere utskytingsovertrykk og begrense munningsflammer når det skytes med ild- våpen, hovedsakelig av typen automatiske luftvernkanoner med større kaliber. Ved at drivgassene tillates å ekspandere i et kammer (5) når de har forlatt våpenløpet, reduseres overtrykket, idet kammeret (5) har sitt eneste innløp (4) ved våpenløps- munningen (1) og sitt eneste utløp i mot- satt ende, ut mot en spredeformet flamme- beskytter. Visse kritiske forhold mellom de enkelte inkluderte komponenter foreligger.Method and apparatus for reducing launch overpressure and limiting muzzle flames when firing with firearms, mainly of the type of automatic caliber guns of larger caliber. By allowing the propellants to expand in a chamber (5) after leaving the gun barrel, the overpressure is reduced, with the chamber (5) having its only inlet (4) at the gun barrel mouth (1) and its only outlet at the opposite end. out against a spread flame protector. Certain critical relationships between the individual components included are present.
