Another configuration of the Stirling Engine. This is the Rhombic
Drive. There is more information about this drive on Roy Rice's site
In the above displacement engine a heat source is applied where
the red arrow points whilst the fins are cooled. (Blue arrow)
The displacement cylinder (terracotta colour) moves back
and forth inside the main cylinder. Air is free to move down the
sides of the cylinder.
This layout of engine works in the same way as the previous page.
What a wonderful design!
