Idea for pneumatic full auto.

I was thinking today, and came up with an idea that I think is pretty good. Its a way to have adjustable firing rates on a full auto marker, without electronics. its a system i have dubbed P.A.F.A. (pneumatically actuated full automatic) firing system.

please see the following diagram, as it will be referred to for the rest of the explanation.

Ok, so heres how it works. as air leaves the valve (im using a CVX valve for the diagram because thats what tippmanns use, but it could work for anything) into the powertube (again, only due to tippmann use. could use any method of controlling blowback gas). it leaves the power tube the same way it leaves when it is being used for a cyclone or RT, only now it connects to a flow control valve. more on that later. after the flow control valve, it connects to an on/off valve. that on/off is controlled by the trigger.

after the trigger is depressed, air is allowed through the valve. the air then goes into a piston in the gripframe. that piston trips the sear. once the piston has opened to the length necessary to trip the sear, it will vent the gas inside through a hole drilled at the appropriate height.

now for the real beauty of the system: full auto ROF control. you will be able to adjust the volume of air allowed into the system due to a calibrated flow control valve set to intervals of say, 10, 15, 20, and potentially 25 bps. this will slow down the rate at which air cycles through the system, increasing the time between when the piston trips the sear and when the piston returns. due to the constant supply of air, the gas in the piston will extend it and then vent out through the hole, only to be replaced by more gas, repeating the process.

the manual system primer pushbutton is required in order to set the system up for the first shot.

it would release air into the gas line until the trigger was pulled, so that the trigger would have some gas to release and begin the process.

the buttons function could be easily connected to the cocking lever, so that only one action would be required to ready the marker for firing.

i came up with this idea by thinking about how the e-grip trips the sear. i then thought, "hey, wouldnt it be great if we could have full auto that didnt require substantial timing or batteries?". this could fire faster then the RT. I know its not necessary, but remember the factory F/A?

same purpose, only basically no timing involved.

its like the RT, only its ACTUALLY full auto.

any thoughts?

Thanks, i like to think i have screwed up and then fixed my marker so many times that i know the ins and outs of how it works.

i really think this could work.

Fully automatic is illegal in certain countries.

let me go ahead, make a blueprint of your idea with my name and get a patent on it and if it works I'll give you 5% of my profits  ? 

why not, if you have the time and a little green, patent that thinga-ma-jiggy     Its the worst feeling in the world for someone to be making money off your idea.

It costs quite a lot. I remember doing a little research into patenting something ahwile ago that I came up with while lying in bed. Then I saw the price and forgot whatever genious idea that was.

You could always try a poor mans patent.

It wont work.

do a poor man's patent. Make blueprints and mail them to yourself. When you get the mail back it will have the official post-marked date on it. If anyone else patents you just show you had the idea before them. I know it works something like that, might be a little more involved, but it's cheap. 

I love this idea.  It seems as though it would work.  A for the patent, it's $500 to file it, and if it gets approved, it's $700 extra to get it issued, but when you could sell the patent for thousands or make lots of money by being a partner with Tippmann, I think it's worth it.

That only works for copyrights.
