I am short of time so I will expand on this post on a later date.The picture is pretty easy to decipher.Enjoy Ladies and Gents.

But there is a few up-sides to this valve.No Air compressor is needed,and there doesn't need to be X amount of more fuel used.


The 'piston' as it is called is indeed threaded and its merely something I stole from an internal combustion engine except there is threads instead of it just sliding.It is filled with metered fuel then 'wound' up to a compression level which a wrench on the end and fired.Its only a concept I was contemplating in maths.

I am indeed thinking of making this in small size maybe in 25mm pipe which i can easily get threaded the whole length.

Cool. I like it. MAKE IT! lol.

Yea, thats good thinking and designing. I see one major problem -- Whats keeping the plunger/compressor from shooting out of the back when fired? You would need a really good locking set up to hold the plunger/compressor in the closed position.
Other wise great design!

is it just me or dos the plunger look like it has threads on it ?
anyway that is a smart desgin i might try it in a smaller verson

if it works u need to think of a name for the design

Very go. interesting that this is the basic idea a car engine works on. compressing gas and air then bang. :violent2:

This is also the basic idea behind DR's Generation II Hybrid, except instead of a threaded plunger you use water from a hose.

The plunger is threaded and you use a wrench to compress the air. rna told me on msn.

this seems like a different interpretation of gen 2 hybrids.

As Mark stated, this design is simply reducing the 'chamber' volume, creating a higher concentration. So your sole objective is to reduce the chamber volume after the mix is added.

As DR has done, along with others the water is simply more versatile. These threads present a problem in there inabilty to seal, and the slow rate of compression. I think you were trying to be unique in your design, but as I can tell, aside from transportation this provides no advantages. Possibly have a piston in a tube, with some all thread on it to provide this compression?

teflon tape should work right? and this would be cool for a rifle application...cheap too!

Such would become ineffective in the event that the rotation of the threaded surfaces is 'reversed' from its previous state. One really big problem I can see with the design is how are these unusually long threads created? Sure such could be created with proper machinery, but from my understanding you, RNA do not have such equipment.

You wouldn't have to thread the entire female part (chamber), just part of it. The male pipe part (plunger) would have to be completly threaded except for the very end where you would have o-ring grooves and o-rings (to seal it), and you can get the guys at homedepot to do it if you ask nice and give them some cash "under the table" so to speak, or buy a ratchet thread set for 30 bucks from some tool supply to thread the plunger.
This design might not work if you get into large size piping, or it would be extremely hard and expensive to do.

Pimpman22-I have to my avaliablility a drilling and milling machine 3 metal lathes with 150mm material capacity and a metal worker for an uncle.Tools and equipment are no problems but the 9 hour drive is a pain in the ass...If you follow the link bellow that is the Engineering company my Uncle owns feel free to look around I recon its damn cool.

Thanks for the kind words.And I had no idea how DR's Gen II hybrid worked,now it makes sence!
