Blowforward popoff valve concept

[bookyle]

Hi everyone. This is just something that occurred to me while I was day dreaming.

It kind of combines this

with this

to make a full auto blowforward valve

If this have been posted before, sorry, I didn't search thoroughly enough

Could be an interesting project. Maybe we could convince JSR to attempt it?

Thats not quite the same man, this one uses the steped design that you use on you rattle snake pop off so i think it would work, the only thing is when a pop off valve moves, it only moves very little.

This is the reason why I added the green shut-off valve, the idea is that the bolt can be made airtight enough to ensure it blows forward far enough, without encountering problems from incoming air on the return stroke.

Umm... and mine doesn't?

Oh, sorry JSR, didn't see that thread.

But you have to admit, this is easier to make

The question is, will it work as mentioned previously, getting the bolt to blow forward enough is an issue, and also consider the air that will be lost until the bolt seals, it would be quite wasteful in practice.
