Abstract (en)
[origin: CA2042205A1] In order to reduce the concentration of propellant gases in the combat compartment, behind a weapon barrel, a smoke extractor (8) is arranged in the middle area of the barrel (7). This smoke extractor (8) is connected to the barrel (7) so as to be gas-tight to the outside and is connected to the inside to the bore (5) of the weapon through an oblique blow-off passage (3) and through Y-shaped valve passage (2). The valve passages (2) are closed by a non-return valve (6) in the form of a spring packet made up of stratified leaf springs. This ensures that the smoke extractor is filled with propellant gases and also ensures very rapid closure of the non-return valve, which is decisive for achieving the desired long blow-off time for the gases through the blow off passage (3).
