One word: TNAK!

I see. Though without changing the piston's effective surface (THE thing of a popoff), that kind of designs tend to go farting, as we learned from your experiments. But the idea of shutting off the air feed is about the same, yes.
Technician1002, I didnt go in detail about the main piston of the popoff / snapvalve because we all know that part. O-rings could indeed be a nice addition, and with the proper hole placement and piston length, allow an air spring to be used.
I would also use a stepped piston that seals via an o-ring instead of a sealing face, as a sealing face starts to leak when the popping pressure is approached.
I think that the sliding rod thing may be unnecessary. It may even cause even more unwanted air loss. I will keep it in mind for future ideas though.
I will probably NOT machine this valve as I have a better idea that is even more efficient...
