Abstract
A Stirling cycle engine having a reciprocating power piston and a reciprocating displacer operating in cylinders having ports covered and uncovered by the motion of the piston and displacer. Ports of the power piston cylinder are connected to ports of the displacer cylinder through cooling means arranged to cool the working fluid. Various drive linkages are described which enable the motions of the power piston and the displacer to closely conform to the ideal Stirling cycle.
Claims11
A Stirling cycle engine having at least one power piston reciprocating in a cylinder and at least one displacer piston reciprocating in a cylinder, heating means located at or adjacent the upper end of the power cylinder, a first conduit connecting the upper ends of the power cylinder and the displacer cylinder, and wherein the walls of each cylinder are provided with ports which are uncovered by movement of the piston therein toward the bottom end of the piston stroke, the ports of the power piston cylinder being connected to the ports of the displacer cylinder by a second conduit incorporating cooling means arranged to cool the working fluid passing through said conduit.
