Abstract
A valve system utilizes a main valve body with a restricted diameter conduit communicating between a propulsion chamber and rear cavity and a smaller venting valve mechanically actuated to open the rear cavity to atmosphere, thereby causing the main valve body to open to pass pressurized air in the propulsion chamber to an orifice to power a projectile. The orifice has a diameter at least as large as the diameter of the projectile.
Claims7
An air gun comprising:
- a barrel having a volume;
- a bulk air supply configured to store pressurized gas;
- a shot reservoir configured to store pressurized gas and provide a pressurized gas supply;
- a pressure regulator configured to provide the pressurized gas supply to the shot reservoir at a predetermined pressure from the bulk air supply, wherein said predetermined pressure is less than a pressure of the bulk air supply;
- a valve assembly configured to provide pressurized gas from the shot reservoir to the barrel when triggered, wherein:
- the valve assembly is the main valve assembly of the air gun;
- and
- the shot reservoir has a total air volume from a main valve seat of the valve assembly to the regulator of at least 1.5 times the volume of the barrel.
