High-pressure gas from monopropellant decomposition drives a piston to maintain hydraulic output without frequent accumulator recharging.
An adjustable valve passage varies projectile speed without changing propellant pressure, simplifying launch setup for different projectile masses.
An annular propellant grain and segmented pressure chambers sustain projectile velocity while reducing recoil in shoulder-fired cartridges.
A combustion chamber and piston replace air-limited propulsion, supporting paintball firing rates exceeding 20 bps.
