Development of the new four bar linkage Stirling engine

This four bar linkage was invented by Allan J Organ to improve the working fluid distribution in Stirling engines.
As I am searching for the concept of my next Stirling engine I built the linkage using the heat exchangers of the old rhombic engine.
They do not fit perfectly to the slightly different strokes but the additional dead space is minimal.
It is still unpressurized and I have to seal all components.

Have fun watching the video and I am always happy for comments and suggestions.
