Abstract
The fluid expander includes a housing, a drive shaft mounted for rotation within the housing, a piston-cylinder assembly including a cylinder and a piston disposed within the cylinder for converting energy from a working fluid to rotational energy output via a drive shaft. Various adjustment assemblies are provided for adjusting speed, torque, stroke length, and thermodynamic cycles of the device. The fluid expander assembly can be used with external combustion systems, with solar or geothermal energy systems, or with internal combustion systems.
