Abstract : Heat energy is supplied to the hot volume of a Vuilleumier cycle cryogenic refrigerator, or to a Stirling cycle heat engine, with and by the inventive heater module which is disposed within the hot working volume of the machine. The heater module is in contact with the working fluid within the hot volume, thereby more efficiently supplying heat energy to the machine. This invention accomplishes heat input to the most optimum place, namely: inside the hot volume. A preferred embodiment and a variation are taught. (Author)
