Abstract

An injection device for fluid propellants for a fluid propellant gun. The device includes at least one pump chamber for receiving a propellant, with one pump piston movable in each pump chamber. A slide is provided for opening and closing apertures in an injector surface which at least partially surrounds the gun's combustion chamber and which is arranged approximately radially to the projectile ejection direction. The slide and pump piston are configured as mutually freely movable components and a mechanism for developing a pressure is provided for displacing the slide by such pressure.
