Abstract
A diaphragm device for sub-caliber, non-rotating projectiles, capable of being fired by a field mortar with a smooth-bore barrel, comprising a funnel-shaped member (B) for the rear end of a projectile (E) and adapted to be inserted into a barrel (A) and provided with an opening (F) at the tip, directed backwards as it is inside said barrel, and a funnel surface (D), which fits at least in the part end of the mouth thereof, to the outer shape of the corresponding part of the rear end of the projectile, in order to thus ensure the centering of said projectile (E) in said funnel-shaped member, while maintaining friction between said surfaces within desired limits, openings in the walls of the part of the member located behind the aforementioned opening (F) at the tip, for the passage of powder gases through them, a gasket (C) of retention for the gases of the p lvora, which rests against the barrel bore wall at the mouth end of the barrel and centering members (G1, G2) concentric with the aforementioned inner surface (D) of the funnel, and which extend from the outer wall from the funnel-shaped member, to the bore wall, in order to center said surface (D) and the projectile (E) in relation to the axis of the barrel.
