how to make a air powered short shot and stop air just passing by after the munition left the barrel?

hey,
i've got a question,i want to make a air pressured gun, but i wont make one that just lets you build up much pressure, and then in one single shot get's empty. i want to make it like a paintball gun, so you can shoot more than one time with the same pressure tank. i found this : http://www.howstuffworks.com/paintball-3d-gun.htm that must axplain a bit how a paintball gun works. but i still don't get it. and i also found this: https://www.instructables.com/id/Airgun-with-eXplosive-air-Release-Valve/, so want to maybe combine those ideas, like make something in front of the nut of the explosive air-realese valve. that does the same thing as the paintball gun. something that knocks the valve back one time and then reloads itself. i don't have a clue how to do something like that, that's why i ask it.
thanks for your time!

This gun can shoot 'like' a paintball gun, semi or full auto - if your air supply can handle it :D

it has 2 storage chambers. one for firing, the other to replenish the firing chamber. The firing chamber fires, but seals from the storage chamber while it repeats - then it springloads back to sealing the barrel and opening the storage chamber, repeat.
