Abstract

A spring actuated annular movable plate in the combustion chamber of a pyrotechnic gas generator exerts a constant pressure on gas generant pellets therein to prevent relative movement and consequent abrasion and reduction to powder form of the pellets regardless of the extent to which they continue to settle relative to one another as the result of age and continued vibration of the vehicle in which the generator is installed thereby improving the long duration stability of the generator and avoiding overpressurization of the generator that tends to result upon degradation of the gas generant pellets.
