Abstract
A Stirling cycle type engine is disclosed in which a displacer piston and power piston operate within a cylinder due to flow of a working fluid which is heated and cooled by a heater element and a cooler element. The cylinder is divided into an upper expansion chamber and a lower compression chamber by a displacer piston. The lower chamber is defined between the displacer piston and power piston. The upper chamber and lower chamber are connected to one another through a serially interconnected heater, a regenerator and a cooler, whereby the working fluid flows into the lower chamber from the upper chamber or vice versa. The regenerator and the cooler are disposed on one outer peripheral side of the cylinder and vertically aligned therewith. Thus, the radial size of the engine is reduced without reducing its efficiency.
