ABSTRACT:
A multiple-phase Stirling cycle refrigeration apparatus includes four cylinders accommodating respective pistons and arranged within a cylindrical crank case on a circle concentric therewith. The four cylinders and their pistons are suitably dimensioned, the pistons reciprocated with a phase difference of 90.degree. separating one piston from the next adjacent, and the cylinders suitably interconnected to produce a very low temperature station and a moderately low temperature station, the former disposed at the center of the crank case and surrounded by the latter to faciliate the extraction of two temperature levels and to provide particuarly low temperatures in the very low or cryogenic temperature region.
