Abstract
A feature of this invention is the provision in an annular piston, annular control valve, liquid propellant gun, of a check valve to permit liquid propellant under relatively low pressure to flow from the supply system into the combustion chamber and to preclude the pulse of pressure generated in the combustion chamber from feeding back to the supply system. This valve allows propellant to be removed automatically from the pumping chamber in the event of a misfire. Another feature of this invention is the provision in an annular piston, annular control valve, liquid propellant gun of a frangible stem which secures the projectile to the cartridge case. The stem breaks to release the projectile for travel down the gun bore when a predetermined level of combustion gas pressure has been developed in the combustion chamber.
