Very nice gun. Mini but damn it can go through German. I wonder if it can go through my Math book, doubt it the formulas are really hard in there. ( Hope someone got that "joke"). Anyway You have to refill your gun after each shot or...?

Yes, he'll have to fill it after every shot. Only rarely does someone make a gun that can shoot multiple times on a tank of air... I only remember 2. (vogt patterns and BBMGs don't count!)
It's mostly a complexity issue, although muzzle velocity also takes a hit.

I'd say soCronic. The air gets pushed out through the barrel and im pretty sure that'd leave the chamber empty or almost that way. But personally I feel I should'nt post here, due to the fact that I don't know how that gun works. I just don't understand it at this point.

Well you can attach a container to it and let the fireing chamber fill for each shot and then stop the air flow from the air container to the firing chamber and then shoot out the projectile as normal. And when you want to fire again you release the air flow from the container into the fireing chamber to get enough air for another shot. Would that work?

<stabs self in gut repetedly>
It's a co-axial diaphram valve... the spudtech forums has some explaniations of them, you could check the wiki, or you could see the "punisher valve" localy.
The handle is a blowgun, being used as a pilot valve. These things can be purchased for about 5$+S&H On ebay. Personaly, I got mine at Home Depot for about 6$... but I'v heard they come cheaper.
Check the wiki for any terms you don't recognise.

You said that marbles were a perfect fit and I beleive you are desctibing it as a 3/4" barrel. I have probablly shot 1000 or more marbles over the summer and none of them would be a good fit in a 3/4" barrel.
Most of the marbles I get are a tight fit in a 1/2" barrel and a loose fit in a 3/4 " so I have to drill the barrel . In some other posts I have seen copper tubing used for marbles. With marbles in my pocket I went to the hardware and none of those will work either unless you use something much larger than the marble like the 3/4" and it is not even a close fit.
