Here is my new Beta type, cold side ventillation Manson engine in an animated GIF.
The crank is so simple, but works well.
Less friction on the sealed parts as same like Beta Stirling without any gears! :)
The hot side ventillation is possible too as mine first construction.
The engine has regenerator and this construction can work with flywheel or free construction also!
So, if you have enough money, time and tools for this engine, just build it and call itt Kovács Beta type Manson engine. :)
Here is a normal crankshaft version with original Manson cycle ventillation
and hot side ventillation
