摘要
A cylindrical projectile is introduced into the barrel of the propelling apparatus in such a way that the base of the projectile is in contact with a rear cover plate of the breech block. An enclosure communicates with the barrel by means of an elbow and an opening in the side of the breech block to which the elbow is joined. When the projectile is in place, gaskets seal the barrel off from the enclosure. The latter may be filled with compressed air, e.g., by means of a coupling screwed into a tapped hole. It then suffices to move the projectile forward by pushing on a rod passing through the breech block cover plate. The thrust of the entering air moves the projectile, and the size of the air passage rapidly increases, thus ensuring a maximum propulsive effect.
