Searless Mag Valve? Look Here

[RapidTransit]

I was always wondering what a Mag Valve without a a sear and a spring would look like, my design goals were
1. to keep it as simple as I could
2. Utilize an On/Off Pin
3. Abillity for Fully Mechanical operation
4. And use the same concept of firing
5. Minimize orings theres 2 for the bolt, and 3 for the the firing chambers
6. Use all of the air! No QEV's etc all air exits down the power tube tip

Why would I even think this?
Faster Recharge rate, make the volume smaller in the power tube, but the end piston larger for more potential for speed, (more force at less psi)

I used Art of Illusion which is an Open Source 3D Program written in Java that is very robust. Of course there are major errors because I made it in less than 15mins

Firing:


Of course this is just all crazy ideas that would probably never see the light of day at least I hope it dosn't

I've also been thinking of a propane powered Mag


//Edit I posted the pictures backwards the first is firing and the second is ready to fire

can't make hide nor hare of the pics, but you'd have to let me in on how you plan on using all the air to fire the ball.

I'm already making a mag with no sear or bolt spring. it is a more efficient set-up, but also more complicated.

how about some details on specifics on how you plan on doing this?

Basicly what happens is there is three mag type valves, the on off pin flowsair into the middle which pushes backon a piston (when its fired the middle chamber gets sealed), when the pin moves up the chamber gets sealed and air flows into the back pushing the bolt forward, releasing air in one continuos motion so air thats pushing the valve forward dosnt just get vented but rather becomes some of the air pushing the ball, its not to scale at all.

I don't get it, but would this help with E frames for mags, since they wouldnt have to trip a sear?

There are 2 chambers an inner for resetting the valve and an outer which holds air for the next shot.
1. First pic air has filled the chamber
2. Air is pushing the back piston its wedge shaped so after a slight bit of travel its working on some momentum. and air exits
3.See the small little hump? This seals the inner part of the chamber
4. Air enters the middle of the inner chamber
5. Because of the size of the piston vs the size and shape of the hump the air pushes back the valve
6. Near the end of the complete cycle, the inner chamber has little holes surrounding it in the back, air exits into the outer chamber while the piston pushes back and the small hump is no longer sealed so air exits out this way too.

This is kind of an elongated version the valve can be made more compact. I wish I had solidworks or something to do some testing.

I thought I understood it but now Im lost. Are you making the air go out the left of the valve and then flow all the way to the right? Are you making the bolt move to the right and eventually it gets far enough that it breaks the seal on the right and lets out the shotto the right? When you ms painted it why is there blue outside the chambers? I dont understand how the air gets outside the design. What you should do is take an extra 5 minutes and re ms paint it right(including arrows and labels of the important parts of each step) and then take 5 more minutes and type a more detailed explanation of what is really going on. Both ways that i try to picture this working have flaws that I see but again I dont have a real clear idea of what is going on.

Ill try and animate it on AOI and try to make a clearer explanation. Putfile resized my file otherwise you'd be able to see the text, that I wrote.

Air flows towards the left pushing back the bolt, at the left end the really large piston, air pushes this to break the seal at the very right. The little hump is there to seal the inner chamber when the bolt is moving left and then it opens up as air enters, so when its ready to fire there isn't air resistance of the the middle left piston when its firing, after the cycle this little hump seals the inner chamber again so the small piston can push back again.

I guess without showing an outline of the body and more details on the parts I just cant totally see what is going on. I think I understand the basic idea with this but I cant give you help or criticism without seeing more of how the body would seal around it and where air is stored.
