I need help about double acting stirling engine

[msb95]

Hello friends
Can anyone help me about double acting stirling engine?
I need some information about it.

I have drawn one up but have yet to build it. My version will have two seperate displacers with each hooked to each end of the double action piston/cylinder assembly. There is a thread here http://stirlingengineforum.com/viewtopic.php?f=1&t=360 that shows some examples of working double action Stirlings. It's been done and it works. It is also easier to pressurize a double action from what I have read.
