ABSTRACT:
A Stirling-cycle refrigerator including a compressor portion having two cnders with respective pistons therein, and an expansion portion with a cylinder having first and second distinct spaces and with opposite ends of an expansion piston in the distance spaces. The two cylinders of the compressor portion are connected by respective conduits to the two spaces of the expansion portion. The end of the expansion piston in the first space has a regenerator therein. The two pistons of the compressor are driven 180.degree. out of phase, whereby to simultaneously induce compression in the first expansion portion space and expansion in the second through respective conduits.
