Title: Folded guide link stirling engine

Abstract: A folded linkage for coupling a crankshaft and a piston undergoing reciprocating linear motion along a longitudinal axis. The folded linkage has a guide link with a first end coupled to the piston. A connecting rod couples the distal end of the guide link to the crankshaft which rotates about an axis that is orthogonal to the longitudinal axis of piston motion and located between the proximal end and the distal end of the guide link. A guide link guide assembly supports lateral loads on the guide link at its distal end. The folded linkage may be applied to couple the compression piston and displacer piston of a Stirling cycle machine to a common crankshaft.
