Ok I need to have a photo of these internals shown to me because it makes no sense how the little tank fills with air and only opens when the qev pops, the ace scratcher for me is it's like two inches back from the tank how does that act as a valve? Call me stupid but it makes no sense to me haha.
For it to fire, a pilot valve has to empty the pilot chamber. Usually this is manually operated for a single shot, but by putting a safety valve as a pilot means that it will fire every time pressure reaches the pop-off level.
It's very well explained in the video, you are stupid

So basically you replace the blow gun trigger for a qev to make it full auto? This seems relatively simple thanks!!! Now I got to go make a trip to ace haha!

a qev works like a barrel sealing piston valve: http://www.spudfiles.com/forums/piston- ... t8157.html (second one down)
it seals against the barrel and moves back when the air is released from behind it expelling it through the barrel
In the video he is feeding continuous air into the chamber and using a pop-off valve( a valve that pops open when a specific amount of pressure is reached) to trigger the qev by releasing the air from behind the piston/diaphram.
since he is adding continuous air when the pop-off closes it reseats the piston and fills the chamber then the cycle repeats the faster he fills the chamber the higher rpm's the gun will shoot
edit: dang took me a while to write my message 3 comments were made while i as doing it

Yes I believe you should be able to get pop off valves at ace or home depot.

Is a population of 1,800 even enough to count as a town?
Actually, I suppose it probably is. There's a city (St David's) in the UK which had 1797 inhabitants at the last census. Smallest city in the country (and to be precise, that country is Wales)
Anyone want to guess at the second smallest city in the UK?
Believe it or not, it's the (City of London), with a population of 7,185 at the last census. Technically, only about one square mile of the whole area that people think of as the city actually has legal status as such.
Anyway, I'm off-topic. I blame lack of sleep.
