ABSTRACT:
A Stirling engine having a configuration which allow spatial separation of the heaters and coolers. The engine includes four cylinders with passageways connecting the cylinders such that a direct fluid connection is formed between each cylinder and every other cylinder. The configuration of the passageways and arrangement of the cylinders is such that heat energy is not wasted. The spatial separation of the heaters and coolers allows the heaters and coolers to be located in separate environments. The pistons within each cylinder are connected to one or two crankshafts through a connecting device which generates no side thrust on the cylinder walls. Preferably, the connecting device used is a hydraulic connecting rod.
