ABSTRACT:
Free piston Stirling coolers and engines are improved by a spring coupling the displacer to the piston and having a variable spring constant. Controllable variation of its spring constant permits controllable variation of displacer stroke, engine power output and cooler thermal pumping rate and thus the invention is useful for stroke limiting and load matching.
