<p>The subject invention concerns a general method of producing countermass weaponry and is based on the use of a high-pressure system and a low-pressure system with a countermass ( 12, 26, 26', 38 ) acting against the low-pressure system. The high-pressure system ( 7, 23, 23', 36 ) shall, in practice, be formed by the combustion chamber for the weapon propellant charges ( 8, 22, 22', 35 ) while the main part of the low-pressure system ( 25, 25' ) shall, in initial stages, be formed by the storage and acceleration chamber for the countermass. The advantage of the subject invention is that said invention offers a possibility of achieving lower pressure levels around the grunner without, for such an end, diminishing the range of the weapon ( 1, 13 ).</p> |
