pump in 2 floors

[redhight]

Hello I wish to realize a pump in 2 floors in a tube 16 mm in diameter which will slide in a tube 18 mm in diameter, I do not understand the principle of a pump in 2 floors you could help me to understand.
Thank you in advance.

Are you french?

[Mimikool]

It's a pump which, when you go down th stim, you compresse air, but when you go up, you compresse the air too.

You compresse air in first chamber when you go up the stim, this air go one the second chamber for being compressed in your tank.

But you can have mulitple stages, mor than 2

Sorry for my bad english ^^

I've found i understand very well what he say, i know why now

[Gun Freak]

Haha he must be french... Probably meant 2 stage

[saefroch]

And it sounds to me like he's attempting a coaxial design... Which I've never seen anyone build.

An effective two-stage will have a large disparity between the two diameters... that is to say that a 16:18 ratio isn't very useful, but with the design I built which uses a 4:1 ratio is more useful.

Most people call them "Two Stage" pumps

Here is how it works:

G-man has made a coaxial 2stage pumps, for his mk-III.

Hello, yes I am French.
Mimikool I am not registered on the forum of your link.
I have more or less understood(included) the principle, but how G-Man made to make a pump for 2 floors in 2 tubes? Thank you in advance.

Thank you but there is 2 tube I would like to make one in a single tube of 16mm which slides in a tube 18 mm in diameter to pump we pull the tube of 18 and we move him forward and behind as that of G-Man

have a look at the FX pump patent: http://www.google.com/patents?id=zPIQAA ... &q&f=false

Not that your english (however you're producing it) is all that bad, but are you using a translator? It seems like all your structures are directly translated...

[redhight]

Yes I use a translator I am bad in English to sadden.
I includes your link jackssmirkingrevenge can you explain to me of advantage.

[saefroch]

I highly recommend Google Translate. If that's not what you're using already... It's difficult to understand what you're asking about the patent...

[redhight]

Okay I'll use google to translate and my 2-stage pump compred I do not yet how did Gman into a copper tube with 2.
Can you explain a little.
Thank you in advance.
