solenoid to pilot a hammer valve

wyz2285 · Thu Nov 03, 2011 4:11 am

I know, I have already printed your diagram dewey-1, as soon as I get all the parts I will start making it. Could you teach me how to adjust the fire rate? Ps: I have to mod the valve again, apparently the 12v battery I bought isn't as strong as a car battery

run more batteries in parallel or use a weaker spring?

weaker spring, of course.
The battery pack is already big and expensive. Btw dewey-1 thanks for the link

Make sure to print the one with the comments on it. Not the early one I posted.

What type is the battery? Picture and/or link please.

1.2v cell connected into two 6v packs, then connect them into a 12v pack, 1000mAh only sadly

Are those NiCd AA size cells or something else. A link will help me solve the problem.

I know NiCd sub C size will work.

wyz2285 · Thu Nov 03, 2011 12:57 pm

Yes they are Ni-Cd AA cells, well I would post a link buy I bought them from a local electronic store

and they this type is all they had, hope they works

And well... is burst fire possible without complicating too much? Sorry I know I had said that it´s not useful but I found out that a lot AEGs have that option

If they are Ni-Cd they should work OK.
Is there any part/model number on the battery?
There usually is for identification purposes.

wyz2285 · Thu Nov 03, 2011 1:16 pm

I think not... I bought these cells individually then packed them.
camelion Ni-cd 1.2v AA 1000mah, that´s it

Basically you bought these.

Looks like yes

but my are cheaper

How mony shots will they make more or less?

it is possible... though do you have a loading mech on that ?? if you don't then what's the point of adding that feature ??

It would be more practical to get an aeg (I assume you want it for airsoft ??). Seriously, you need an air chamber for that an as much batteries as you need for an AEG. So what's the point ?

Too be honest I don't like your design at all. Your using electricity to do what it does worst (I hope you get what I mean). This wouldn't be such a big deal if it was machined, as that would help to reduce friction, but it isn't. Lol I probably sound very negative.

wyz2285 · Thu Nov 03, 2011 2:36 pm

The valve stem is polished on a lathe first

low friction.
I want more power than a AEG, this valve+800psi

and a AEG needs more battery, my goal was a gun simular to baikal blackbird.
Again, this valve is also the reloading mechanism, see the first diagram I posted.
(I bet you were very positive if I had used the 3-way+cylinder option

)
Original thread where I got the Idea

Now you get it

nah really dude... solenoid 3 way valves do have a small solenoid inside - the only difference is that it is machined and a proven design that serves as a pilot valve for the main valve... so essentially you don't need much electricity to open it
