My "inventions"

[Andrzej]

Andrzei, I think Koichi Hirata has plans for the rotary displacer engine for sale on his site, have a look o google, most of his stuff is in both English and Japanese. His motor looks very much like yours, maybe you should get in touch with him, he has a Q &A section in his web site, but I think you might be able to contact him.
Build a conventional engine and get that working well, then you can start experimenting. If you design the first engine well, you will be able to change the displacer for a rotary one, do'nt worry about pressurization on the first one, get that going and then see what happens. Ian S C

Hi!
I known all Hirata plans and drawings. Few times I was send emails to Him - no answer....
As I wrote earlier, I solved the "pressurization problem :)
Thanks for all...
Either your attention and criticism helps me to work on the engine
Best and warm regards
Andrew

PS
In the current work, I found a great way to improve the ideal heat transfer in rotary displacer chambers...
Not patented yet!
:)
After I will try it - I can exlapin and show You!
:) :) :)

I think you have to E-Mail him on his work site, not his private one, not sure what it is, but its on the web site on google. Ian S C
