Cheap semi-auto
Posted: Tue Nov 25, 2008 12:23 am
I posted it here rather than the BB section because it would be easier to use as a standard pneumatic cannon without change barrel size.
Please take a look at the diagram and tell me if you think it will work. Also, does anyone know where to obtain a check valve such as the one depicted in the digram? (Spring keeps it closed, opens at certain psi)
How it works: Once connected, the chamber will instantly pressurize (or at least very quickly pressurize). When fired, the pressure will open the check valve, enter the barrel, and fire the projectile However, the difference is that the chamber will begin to repressurize as soon as it loses any pressure. This would usually result in some air escaping into the barrel if the pilot pressure has been completely exhausted. With the check valve, however, the air will not enter the barrel, preventing any misfire from it. Using this, I hope to achieve a true semi-automatic cannon which is also fairly easy to build, as well as cheap, for people such as myself with limited resources.
