As you can see when you move the pump back it allowes pressureised air and fuel to fill the chamber (Both sizes specificly for ratio and how much is needed for each shot), as well as blocking off the two chambers and allowing a paintball to drop into the chamber (The other one :P) When the pump moves forward it blocks off the feedneck and gas inputs and mixes the fuil. Spark and boom.

This is the first time ive looking at the consept of a hybrid so please tell me if this would work, cheeres!

Honestly, to me it seems like one of those things that looks great on paper, but actually making it and machining it and making it work would be a pain. I think its beyond the average spud gunner's ability to make, however if you have to tools and the knowledge, go for it.

"physics, gravity, and law enforcement are the only things that prevent me from operating at my full potential" - not sure, but i like the quote

you know you are not an engineer if you have to remind yourself "left loosy righty tighty"

Well you're going to have a great load of fun trying to get everything to seal properly, not to mention preventing that pump handle from shooting out farther than your projectile. I see a lot of dead space and bottlenecks, which will decrease performance as well.

I would condense the design down to having a dedicated pump handle for the loading of ammo and a separate valve for fueling. While this may compromise a bit of compactness, it will result in a more feasible build.

I think you've overcomplicated it, as I think Tippmann did the same. Tippmann's design is loosely based off of a Sheridan valve, and yours appears to be the same way. I think that if you were to make an inline version, it would be a bit easier to build and be even more compact.

An inline combustion tends to get slightly better performance than an over / under. If you were to place a pump actuated meter onto this chamber (designed so that on one stroke it would exhaust the fumes, and on the other would add the fuel), it would make a for a much easier build.
