This idea hit me a little while ago.
Please give me your feedback.
EDIT: This is how it works: The ball valve is closed and the high-pressure chamber (C1) is pressurized using the Schrader valve. (Ideally this chamber would be made out of metal to withstand extremely high pressures, but it would work with PVC also.) The ball valve is slowly opened and the low-pressure chamber, connected to the cannon's valve, (C2) is pressurized by C1. C2 is overpressurized by C1, and the pop-safety valve is triggered, and the ball valve is closed as fast as possible. The pop-safety valve releases air until C2 is no longer overpressurized. C2 is now pressurized and the cannon is ready to fire. The cannon is fired and the cycle repeats until C1 is no longer pressurized.
The secret is the pop-safety valve. The pop-safety valve acts as a regulator. For this setup to successfully work, however, C2 must be smaller than C1, and the pressure in C2 must be regulated by the pop-safety valve to be significantly less than the pressure in C1.
^^^ For example, if C1 were 5x as large as C2, and C1 was pressurized to 30 PSI, C2 should be able to be pressurized to 30 PSI 5x. And if C1 was pressurized to 150 PSI, C2 should be able to be pressurized to 30 PSI 25x! That's 25 shots from one charge! (Theoretically.) Therefore, this setup would work well in cannons that work well using low pressures and lightweight ammo, such as paintball cannons. (I know that's what I would use this for.)

its not self explanitory, what u have there looks like a air compressor without a pump, where does the co2 come in?
and why did u draw it in flash??

There is no CO2. It's the "solution" to CO2 because it's portable and inexpensive.
I drew it in flash because i have skills in flash and I don't have skills in anything else, and I want to animate it eventually.

Would'nt you have the same problems with any other high pressure gas source? That high pressure is still gonna blow up your chamber regardless of what gas it is. I think you overlooked a huge part of why CO2 is regulated.

OK, I guess I was wrong when I said self-explanitory! I'll edit my original post right now and post directions of how it works.
I'll post a simple flash animation later or tomorrow of the whole process. I just made the animation but unfortunately I don't have access to the computer that has it right now.

i second mrcrowley, just do that. it's quite simple.
While a gauge should be on the small chamber (and the big chamber), the pop-safety valve needs to be there also. The small chamber should fill up very quickly... are you saying that you're willing to put your life into the hands of your reflexes? If you're charging a PVC C2 (without a pop-safety valve) to a high pressure from a metal C1, you don't have room for error. Too many PSI in the chamber could be fatal.MrCrowley wrote:why dont you just use a gauge instead, the small chamber could hold 125psi and when it says that on the gauge you just turn the ball valve of.
The pop-safety valve is to this setup as the regulator is to a CO2 setup. It's not there for safety reasons so much as it's there to regulate the pressure of C2. C2 would not be charged to 125 PSI... while it could handle this pressure, it would defeat the purpose of this setup, which is to give the cannon many shots from one charge.
here's the real solution use a metal chamber (due to brittleness of pvc at cold temperatures) and one of <a href="http://biketiresdirect.com/productdetai ... ">THESE</a>

most pipe i buy is rated to around 250psi and depending on how big the first chamber compared to the second i could easily turn the ball valve of and its not like as soon as it gets to 250 it will blow,or just use a metal chamber.and you loose air when the pop off valve is activated and you loose it very fast.
edit: how man psi do you want in chamber 2 as if you go above 200psi metal is the way to go really.and you already have one metal chamber so might as well make C2 metal as well.

OK I'll try one more time to explain it. C1=high pressure (150 PSI (PVC)); C2=low pressure (30-50 PSI). C1 > C2. This way C2 can be charged multiple times from one charge of C1.
The point of this setup is to NOT USE C02 to get many charges because CO2 is expensive.
The pop-safety valve may open and lose air fast but it only loses it until it reaches the set pressure and closes. A pop-safety valve set to anywhere from 30-50 PSI would work, the ball valve would just need to be closed as soon as the pop-safety valve is activated so that little air is lost.
