Solenoid actuated hammer valve

[wyz2285]

My 12v DC solenoid is working
Now I´m using it to pilot my chamber-seal piston repeater 8)
The video shows the system in function, also you can see the piston moving
The circuit testing part is for Dewey-1, it´s still not working in full auto mod also take a close look at 2:15, it fires both when I press/release the trigger

thats so awesome
are you going to have a bolt system moved by the solenoid or are you going for a simple T-mag?

[wyz2285]

The test was done at 60 psi...
I´m going to run this at least 200 psi so I will have more than enough air to use a blowback

[dahakka]

u r really really awesome ...
and ,can i ask you a question?


How many shots do you get with that tank , in 40bar?
i still want to do 1 like that,

(i don't want to make qev+slide valve or 3 way valvebecause i don't have pressure regulator and hpa tank,so your design is best for me, ...

[wyz2285]

The best thing about that system is that you loose very little air, as it does NOT exhaust the full pilot air, a slide or 3-way always exhaust all the pilot air. I did the test, my system makes 1/3 more shots.
For your question, I don´t have answer never really finished shooting all the air, normally after 30-40 shots I remove the flow stoper from the blowgun and finish the air with one big shot .

wow
i watched video
and i think you only can shot 3 or 4 times
that s stupid
i still can't make a "pop off" valve like your , sometime it doesn't work, sometime it "Bang" and run out off air
i will try again
thks for help

I only shot 3-4 times, because my neighbores can´t stand de noise

great, move over Steve Harper

Even through it's working great now, I realise that I will need a big chambar, so if I want to make this PCP style, I will need to build a inline regulator, I know how they works, my concern is making a reliable and functional one on my drill press damn I want a lathe!

It's cool but not very practical at this stage, because it lets too much air out... but still cool. I'm looking forward to seeing what you'll do with it.

[wyz2285]

It let's too much air out because I'm controlling the solenoid manually, with the control circuit that Dewey-1 had designed for me, the shortest valve opening width is only 50ms, and wil allow me to switch between semi/full auto, also the fire rate. And this thing at 100psi has the same noise as my hammer valve at 30bar... So power is not a problem.

[Gun Freak]

Ok cool, I still think you will need a large air tank

Thanks great, be sure to keep us updated

Very nice work, I like it!

i was looking at these valves on ebay for the exact same purpose, but i wasnt sure if they pushed or pulled :/ anyway could you tell me which valve you bought? this would solve so may problems in my design, such as trigger placement and working out a hammer mech etc
