new co-axial piston with suppressor

[CS]

Hmmm, just had a thought.

Frow what I understand silencers in theory, is that they essentially realese the same energy over a shorter period of time yeilding a 'queiter' noise. So if a silencer that was constructed correctly with 'holes' in the outer jacket, wouldnt it yeild a similar reduction of peak energy by increasing the time the energy is exerted over, while increasing the area in which the energy is distributed over, thus reducing the 'sound'. That sound right?

Yep. That's why actual guns with silencers aren't as powerful.

thats why most guns dont actually use silencers, they use supressors. the difference is that silencers actually decrease the velocity of the bullet while supressors just muffle the sound

This link should lead everybody in the right direction as to how silencers actually work... http://people.howstuffworks.com/question112.htm

Exactly, supressors and silencers are completely different. He's using a supressor NOT a silencer. So as interesting silencers are, it's off topic. Not that I care, I'm actually very bored. Now who's off topic.

I have some of my own questions, where is the barrel? and if its really a coaxle isn't the sprinkler valve overkill for that size? you could use a blowgun for that in fact wouldn't using the sprinkler valve as a primary valve make it stronger?, and why is the hose barb on the blow gun still?

edit: wow how did I end up posting here this is old I think I forgot when I was searching

[jackssmirkingrevenge]

Old topic but some of the suppressor "facts" expressed at questionable at best

its my theory that as the projectile reaches about half way through the suppressor alot of the pressurised air behind it will escape through the holes in the barrel then travel through the sound absorbing material and then exit out the holes in the outer shell. kind of like yelling into a pillow will reduce the sound of your voice, the air waves from your voice still exit the otherside of the pillow but its is very muffled.
anyway its just a theory, any thoughts?

Try yelling into a pillow made of airtight plastic and you'll see the difference

So what does this prove? sorry, i sometimes dont analyze correctly. Would it be better to make one with holes, or without? And is there any other type material i can use to put in the supressor to reduce the sound rather than steel wool?

There isn't a single commercially available suppressor out there with holes in the outer casing, for the simple reason that it worsens performance.

Steel wool works best for combustions, since it serves to dissipate the heat of the propelling gasses and therefore reduce their pressure. For pneumatics though you're better off with softer materials like cotton wool or scouring pads.

[SpudUke5]

Ok thx. Cause i thought of making a supressor and i just did find some steel wool laying around. But yea i can get some cloth to shove in there. Thx.

Don't get busted with that silencer man... Prison time.

it depends, but the risk is certainly there - have a read through this page.

ok ok but there are silencers used in pnematic equipment, for example they are placed in exchaust ports of QEVs...

I think that holes in the outher casing of a silencer would help (ofcorz if the silencer is packed tightly with wool or simmilar material that would slow down the gases considerably )
because the pressure can be released gradually before the bullet leaves the silencer

volume of air released in spudguns is much higher than in most airguns so silencers without holes can work fine for airrifles....

It's better to let the gasses expand and lose pressure first, then release then through the muzzle.
