Abstract

The firearm uses liquid propellant, having a first lengthwise cavity in a housing (10). A barrel (8) with discharge bore (20), a chamber (22) for the projectile, and a combustion chamber (120) along a lengthwise axis is accommodated in the first cavity, and forms with the housing a second enclosed cavity, annular in shape and coaxial to the barrel. A tubular stop valve (36) slides coaxially to the barrel in the second cavity, as does an annular piston (38), the valve and piston together forming pump chamber (118) for the liquid propellant. Seals (32) are included to seal the rear end of the projectile chamber. A feed system (151) delivers liquid propellant under pressure, and first and second passages (126, 128) connect the pump and projectile chambers. Seals (26a) on the projectile prevent propellant escape from its chamber to the combustion chamber at low pressure, while allowing it at high pressure.
