High Pressure?

[cannon freak]

I was wondering if this is at all a possible way to create high pressures

I was thinking about pressurizing a 4" PVC chamber to 120 PSI and then having an encased 12 volt air compressor inside, could that compressor pump much higher pressures. Would the compressor have enough torq? Will it stall? Is there any way to solve that problem?

Or is there some major flaw in the whole thing?

I dont get why you have an air compressor and a hand pump and is the hose leading out of it to suck in air for the compressor?

A normal air compressor compresses normal atmospheric air at 14.7 PSI I was thinking that if you were to make the pressure out side the air compressor 120 PSI than the out put would be much greater. The hose leading out would be some kind of high pressure hose to handle the pressure.

I don't think that work, the compressor is designed to put out a set pressure there for it won't put out anymore then that pressure. It would ether stall or more likely just let the compressed air straight thought without compressing it further.

If you really need more then 250 psi you should just use co2 or hpa.

You would run into many unseen problems. Also, I don't think that a 12 volt compressor will fit into 4" pipe.

I really don't understand why you would put the compressor into the chamber lol this is one of the weirdest (sp) ideas ive ever seen... but most compressors that are 12v can't handle sh*t so i'm thinking you won't get it up past 120 with the compressor any ways...

Its true that the comrpessor is designed to put out a set pressure, but usually the pressure is measured relative to the outside air, not absolute, so it should increase the pressure relative to what the pressure int he pipe is. It also wouldnt be significantly harder for the compressor to do the work because the actual difference between the output and input owuld be the same. The tank pressure owuld help the compressor pressurise it. It probably would also let the compressed air straight through, but when the pressure on the hose side reaches 120, it would start compressing.

However, i can see the actual structure of the compressor failing. Its not made to be stored in 120 psi. assuming your compresor was made of steel or something, i guess it would work. Unless im overlooking something. which is likely. i havent actually studied compressors.
