ABSTRACT TWO-ELEMENT WAD WITH PNEUMATIC DAMPING Two-element wad with pneumatic damping designed for the cartridge industry formed by two interchangeable elements connected to each other and which consist of a case (1) and a damper-shutter (8). The case (1) incorporates a series of foldable flaps (7) and a valve (2) that regulates the damping and injects air. Both the case (1) and the damper (8) have cross-sectional walls (3) and (9) of aconvex-concave shape and can absorb radial deformations to the symmetry axis of the wad. The damper (8) has a four-fold action: it supports the flexion and deformation of the material, the friction against the walls and the compression Or the air contained.
Bourre de cartouche en deux parties avec amortissement pneumatique, destinée à l'industrie de fabrication des cartouches, constituée de deux pièces interchangeables qui peuvent s'assembler et correspondant à un réceptacle (1) et à un amortisseur-obturateur (8). Le réceptacle ou conteneur (1) comprend une série d'ailettes rabattables (7), ainsi qu'une valve (2) pour la régulation de l'amortissement et pour l'injection de l'air. Tant le conteneur (1) que l'amortisseur (8) ont des parois latérales (3 et 9) de forme convexo-concave, et peuvent absorber des déformations radiales par rapport à l'axe de symétrie de la bourre. L'amortisseur (8) a une quadruple fonction: supporter la flexion et déformation du matériau, la friction contre les parois et la compression de l'air contenu.
