  • Precision Control of Operating Pressure for Pneumatic Guns
    Publication number: 20100300420
    Abstract: A pressure transducer or other means of measuring pressure inside a vessel is used to measure the pressure of a gas inside a pneumatic powered projectile gun. A valve is used to control the pressure inside the gun by controlling the amount of air entering from a compressed gas source at a higher pressure. Finally, a second valve is used to release the gas inside the gun into the barrel section, firing the projectile.
