Abstract

The gun is of the type in which a projectile bolt is an integral extension of a piston which is displaced in a cylindrical bore by a propellant, e.g. an explosive cartridge or compressed gas. That part of the bore on the side of the piston remote from the propellant is now provided with a set of elastomeric collars aligned in coaxial succession. The line of collars occupies the full length of the chamber space on that side of the piston and before firing. However, at that stage the collars should not occupy the full volume of that chamber; when the gun is fired, the collars are axially compressed and expand radially, progressively filling the chamber space. The collars pref. fill the chamber when the piston has travelled abou tone third of the length of the bore on that side of the piston. In their initial state before firing, the line of collars is pref. slightly prestressed by axial compression. A helical spring is pref. fitted coaxially between the collars and the rod of the projectile bolt. Each collar pref. has a coaxial annular groove formed in its outer circumference. The collars are more durable than a coil spring and give better braking.
