Have the trigger lock the ammo in place sealing the barrel, pull the trigger, launch the ammo! Smart thinking!
It's a good looking piston. It deserves a name ???
There is a line of writeing in your post that is way to small to read. What does it say?

Nice design- clean, simple, and apparently effective.
Did you put a bumper in the actual unit? Seems like the metal components could do some real damage on the housing.

| One would certainly be the ease of construction, not to mention the lack of equipment needed.

I'd think this design would also have increased reliability, less maintenance requirements, and probably a faster opening time than comparable valves. Additionally, this valve would probably have reduced weight compared to similar ones (which can be an important factor on some big cannons).
I've been thinking about building a pneumatic marble gun for awhile now; It's been a long time since I've done a pneumatic, and I just got a new compressor. I think I might build a version of this valve with 1" or 1.5" porting. Great design!
Peace,
Pete Zaria.

Thanks guys!
I would say ease of construction is the main pro on this.
I don't know about weight though, a similar piston with a normal sealing surface weighs the same.
Reliability is also a big plus, it will always seal, because it doesn't even need a flat barrelport.
I'll post a picture of what I think sgort means, wich I have thought of before I might add, just never tried, because I never felt like going through the whole trial and error process...
Here is my thought on what sgort said.
Trigger and lock should be metal , housed in something....very strong.
I have made crossbow locks like this and they worked, so why not combine them??
This way it could ( make that "has to") be filled from the chamber side, and it could be reset by hand, and the middle washer is no longer needed..saves some more weight..

Here is what he was talking about -- 
Yellow is the trigger
Red is ammo
Black is the seal, (behind the ammo)
Orange is the air

I just copied and pasted this.
"The front "barrelphram" can NOT be used without the back one. Without the back the front can NOT be pulled out the barrel because of the pressure on the front causing friction."

I have too little time to finish the gun at the moment, you will have to wait.
I'm having trouble with the exhaust valve and I don't like the way it looks.

| Would it be possible to adapt this valve to work in a breech loader rifle?

| What kind of lubricant would need to be used in this valve?
