ABSTRACT:
Method of and apparatus for doing work characterized by the steps of establishing respective hot and cold zones within a constant volume chamber; providing a flow path intermediate the zones and encompassing a caloric energy storage means for extracting heat from gases that are hotter and for delivering heat to gases that are colder as the respective gases are flowed therepast; separating the respective hot and cold zones by reciprocally movable member that is movable longitudinally of its cylinder and periodically reciprocally moving the member whereby to effect the following steps; (a) taking in the relatively cool ambient air into the cold zone; (b) moving the cool ambient air past the caloric energy storage means to pick up heat and become relatively hotter to tend to expand and increase pressure; (c) passing the hotter air from the chamber to an engine means for producing work; (d) passing a high temperature fluid in heat exchange relationship with the caloric energy storage means to again heat the caloric energy storage means and store heat and repeating steps (a)-(d). Also disclosed are specific preferred embodiments and apparatuses.
