Abstract

A belt-advance system for a belt-fed gas-loading automatic weapon, e.g. a machine gun, revises the usual energy flow path by obtaining at its input side a gas-pressure pulse upon the firing of the weapon and providing an energy-storage unit functionally combined with a cylinder/gas-piston unit for transforming the pneumatic energy into mechanical energy for stepping the belt-advance ratchet pawl.
