more details on these poppet valves plizzz

I removed one of them and attached a picture, one with the activating lever (struck originally by the eccentric cam) removed.

Kinda like my design...? Actually, I've been tossing around that kind of concept in my head for about a week

'been tossed around this forum for a while now too, the problem is too much tossing and not enough doing

For the air cillinder, what pressure would it be able to have?
You could use it as a pump, or, as a pneumatic ram

Too large a diameter to be a useful pump, but a pneumatic ram, hmmm...

so are you going to use these poppet valves for a full auto gun?

Possibly, but November is a long way away...

BTW, I found a teacher who could solve ADD (Attention deficit...) !!!
for myself at least

While that certainly got my attention (fuck!), I fear that delicious Eastern European accent would distract somewhat from proper pronunciation, I would recommend this as a proper cure for ADHD

lol AK-47 FTW
@POLAND_SPUD-- Yes, why the heck else would i have that name.

use The poppet valves to make 14 semi auto guns...

What a find, im sure your creative mind will just think of something that will amaze us 8)

vovka351 i guess you like wolfs?

(ps im eastern european, ukrainian, but i dont live there)

What operating pressure do you expect? And whats the diameter/surface area?
Attach a QEV with a reservoir and lets rock

It could be used to propell a hollow arrow, or placed inside of a barrel.
That would be easy to make and might spark a new tradition.
It would save air compared to an ordinary pneumatic, and it should be a whole lot more silent.

BTW: "poppet valve struck by excentric cam" equals "machinegun..."

I took it apart and attached a picture (the vernier caliper is open at 6 inches for scale) , I expect it can take at least 100 psi and with a 40mm bore, that's around 88Kg of force still, looking at heavy duty pneumatic nailers, they have pistons of much wider diameter and work in the same way a coaxial does, so perhaps the power of using this as a ram to actually fire stuff wouldn't be worthwhile. I think it would be more feasible to use it to knock open a large ball valve, hmmm...

BTW: "poppet valve struck by eccentric cam" equals "machinegun..."

That's exactly what I was thinking - for small bores at least, why bother with a piston valve? You could have a linear hammer driven by a motor (in the same manner as the piston on an airsoft electric gun is driven - one could even lift the mechanism from such a gun) that knocks the poppet open at regular intervals. As to reloading, you could either fit a blow-forward valve, or even better, you can have it powered by the motor too out of phase with the hammer, that way all the air from the poppet is used for firing the projectile...

Food for thought... though on the other hand, if I'm going to bother with an electric motor, I might as well make this - easier and less dead space

that's around 88Kg of force

I got a truly awesome idea!
How much do you weigh? Because....
Hey, you know those pogo-sticks kids jump around with?

[jackssmirkingrevenge]

hehe... 81Kg, convenient eh? Though it will more lifting than launching in that case

Interesting to note that it's a double acting cylinder, meaning it can be rocked back and forth, hmmm... and industrial sized female/alternatively inclined male pleasuring device perhaps
