Semi and full auto valve idea

[finland66]

Hello

I was discovering PolarStar Fusion Generator and I got idea of semi and full auto valve MAYBY based to PolarStar but I'm not sure, becose I can found diagraphs for PolarStar.
So theres my idea

[jackssmirkingrevenge]

How does it work exactly? Does the solenoid push the bolt back and forth by alternating flows?

Thanks about those threads
Picture says more than thousand words.
From picture 3 cycle comes back to picture 2

So you are using a solenoid valve to "pilot" a shutoff valve? Good idea, hope it will work

[finland66]

Actually yes.
Now I need to start machining this thingy
Did you get it jsr

The problem I see is this: if the air goes in too fast it might slam that piston up against the front pretty hard and over time could deform the front. Maybe add an o-ring or rubber washer as a damper.

I see no reason why this valve shouldn't work. Are you going to extend the point of the piston to act as a BB injector? That would prevent double feeding.

I agree

Yes. Theres maby bb feeding problem at high ROF.

Do someone have some great ideas for magazine expect thishttp://kuba-t1000.com/minigun/index.php ... t_ammo_box

Interesting... though personally, if I'm using a solenoid valve anyway, I would go for something simpler. Do you intend this for low power low pressure airsoft or something a bit more hardcore?

[finland66]

I planned this airsoft in my mind but I can go higher.
Mayby 800psi and 6mm steel bbs if I can found solenoid valve for that pressure.
Do anyone know where I can get 6mm steel bbs for cheap?

[jackssmirkingrevenge]

If you're worried about the cost of BBs, I'm guessing you haven't checked the prices for a solenoid valve that can take 800 psi...

[finland66]

Yes I know that those solenoids are really expensive.
Can you recomend some other ammo?
BTW: I could use 4.5 bbs but barrel is difficult to find/make.
