Abstract

An injection device for fluid propellants for a fluid propellant gun includes at least one pump chamber to accommodate a propellant, a pump piston movable therein and a device for the measured opening and closing of apertures in an injector surface disposed at least partially around a combustion chamber of the gun and approximately radially to the direction of ejection of a projectile from the gun. The device for the measured opening and closing of the apertures in the injector surface is composed of a slide provided with passage openings, the slide being relatively movable with respect to the injector surface and being displaceable by a pressure generating device.
