Abstract
A rotary heat engine including a central crankshaft and a plurality of cylinder assemblies and a heat exchanger assembly. At least one of the plurality of cylinders, and preferably all of the plurality of cylinders includes a cylinder member, a piston member slidably positionable within the cylinder member, a connecting rod and a rolling diaphragm. The rolling diaphragm is positioned between the piston and the cylinder assembly to define a working volume which is in fluid communication with an opening that is in communication with the heat exchanger body.
