ABSTRACT:
This invention relates to a free piston Stirling engine in which a structure for aiding in the lubrication of the engine is provided. The piston of the Stirling engine is provided with turbine surfaces, such as blades. Working fluid entering the cylinder chamber applies a spin torque to the piston thereby causing the piston to spin and entrain gas about its perimeter for hydrodynamic gas lubrication.
