What primciples does this use?

I came across this whilst looking for ammo loading ideas (please post if you have any good lings) does he just use the blow gum as a trigger and the gas in the small cylinder powers the projectile, and he just restricts flow from the larger cylinder to refill the small cylinder to not use all the gas on one shot? If not the case can someone explain it to me, thanks.

As previously mentioned any ideas or links to ammo loading ideas, still undecided on single shot or multishot so interested in them all, sure it makes a difference but I have a barrel with 15mm od and 9mm bore 600mm long. i would like to be able to swap out barrells but thought 9mm is common slingshot size and I have also seen 8.5mm incase 9s are too tight.

Many thanks in advance.

it uses the blowgun as the main valve and there's a flow limiting fitting between the air tank and the chamber. Not very complicated or advanced but at least it's easy.
