Now please deal with me as this is my first post.This is an idea I can up with for a semi-auto air/spring gun.

The blue is a pvc airtank that holds a constant psi.
The green is a tube that goes into the plunger assembly.
The orange is an airtight O-ring on the plunger and in front of a spring.
The pink is a string that pulls down the front air regulator piece that is basicly a piece of brass with hole in half of it and closed the other half and this is nested between two O-rings. When the trigger is pulled it opens the air regulator releasing the air and the pressure allowing the plunger to move forward. There is another air regulator under the plunger that is opened when the trigger is unpulled and closed when the trigger is pulled halfway back. So every time the trigger is pulled it releases the plunger and stored psi. and then unpulled the airtank pushes the plunger back.


Please note this is theoretical but is quite a good design.

This design has been discussed many times over and I don't even think that this version is feasible. You're "regulator" is a piece of brass nested between two o-rings? And you expect this to be able to maintain a constant pressure difference between the tanks? Not only that, but you really need to draw a much better diagram if you want people to fully understand what you're talking about. I suggest you look at the homemade section of this site to see what a well-done regulator assembly looks like.

Actual no I didn't expect it to hod so I might use something else like a better valve and if the part below the plunger has a one way then it would work I think, this is theoretical.

That looks like the thing in the Wildfire. Or am I grasping the concept wrong?

I don't know, I don't own a wildfire but it is possible.
