Abstract

A Stirling engine having a modular construction including a drive case and a cylinder block with generally flat mounting surfaces that face each other. The cylinder block includes cylinder bores and cooler bores that are perpendicular to the cylinder block mounting surface. Piston rods extend through the plane defined by the cylinder block mounting surface and couple piston assemblies positioned within the cylinder bores to a drive shaft. Piston rod seals contain a working gas present within the cylinder block from leaking into the drive case. The same basic engine components may be used with either sliding contact rod seals or bellows or other types of hermetic sealing elements.
