Abstract
A symmetrical adsorption pump/compressor system having a pair of mirror image legs and a Joule Thomson expander 40, or valve, interposed between the legs thereof for providing a new, efficient refrigeration cycle. The system further includes a plurality of gas operational heat switches 48a, 48b, 48c, and 48d adapted selectively to transfer thereto heat from a thermal load 44 and to transfer or discharge heat therefrom through a heat projector 46, such as a radiator or the like. The heat switches comprise gas pressurizable chambers adapted for alternate pressurization in response to adsorption and desorption of a pressurizing gas confined therein.
