Abstract
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.

Claim 1
Independent Claim
231 words
A method of doing work in a heat engine consisting of a chamber having hot and cold zones at respective ends thereof, a flow path containing a regenerator connecting said hot and cold zones, means movable within said chamber for circulating a working fluid between said hot and cold zones along said flow path, inlet means for the intake of ambient fluid through an inlet work producing means into said cold zone, and outlet means for the discharge from said cold zone to ambient, said method comprising the following steps: a. circulating said working fluid from said cold zone to said hot zone along said regenerative flow path to heat the working fluid and thereby effect the discharge of a portion of said working fluid from said cold zone through said outlet means to said ambient, thereby generating a potential for power output; b. adding more heat to said working fluid in said hot zone; c. moving said working fluid from said hot zone back to said cold zone through said regenerative flow path, thereby cooling said working fluid and effecting the intake of ambient fluid through said inlet means to said cold zone; d. generating a power output in said inlet work producing means as ambient fluid flows through said inlet work producing means to said cold zone to become said working fluid; and e. repeating steps a through d.

Claim 3
Dependent Claim
55 words
The method of claim 1 wherein a discharge work producing means is connected with said outlet means such that a power output is generated in said discharge work producing means when said portion of said working fluid is passed from said cold zone through said outlet means and said discharge work producing means to ambient.
Claim 4
Dependent Claim
18 words
The method of claim 1 wherein said heat is added by combusting a fuel with said working fluid.
Claim 5
Independent Claim
275 words
A method of doing work in a heat engine consisting of a chamber having hot and cold zones at respective ends thereof, a flow path containing a regenerator connecting said hot and cold zones, means movable within said chamber for circulating a working fluid between said hot and cold zones along said flow path, inlet means for the intake of ambient fluid into said cold zone, and outlet means for the discharge from said cold zone to ambient through a discharge work producing means, said method comprising the following steps: a. circulating said working fluid from said cold zone to said hot zone along said regenerative flow path to heat the working fluid thereby effecting discharge of a portion of said working fluid from said cold zone through said outlet means, thereby generating a power output in said discharge work producing means as said working fluid flows from said discharge means through said discharge work producing means to ambient; b. adding more heat to said working fluid in said hot zone to further effect discharge of a greater portion of said working fluid from said cold zone through said outlet means to said ambient, thereby generating a power output in said discharge work producing means as said working fluid flows from said discharge means through said discharge work producing means to ambient; c. moving said working fluid from said hot zone back to said cold zone through said regenerative flow path, thereby cooling said working fluid and effecting the intake of ambient fluid through said inlet means to said cold zone, thereby generating a potential for power output; and d. repeating steps a through c.
