Abstract:
A near adiabatic engine has four stages in a cycle: (1) a means of adiabatically expanding the working fluid during the downstroke from a high pressure/temperature level to a low level; (2) a means of cooling the working fluid at Bottom Dead Center (BDC); (3) a means of adiabatically compressing that fluid from a low pressure/temperature level at BDC to the higher level at Top Dead Center (TDC); and finally, (4) a means of passing that working fluid back to the high pressure/temperature source in a balanced pressure environment so as to minimize the resistance of that flow. This disclosure teaches the means of achieving (2) and (3) as follows: (2) a means is disclosed of BDC cooling of the expanded working fluid in the working chamber, and (3) a means is disclosed of adiabatically compressing the working fluid into the pump chamber before cycling the fluid.

Claim (Index 5):
The heat engine of  claim 1  with a valving system, wherein:\n separation between high and low pressures is maintained by the sequential operations of the valves in the working chamber and pump volumes; \n unidirectional flow is caused by the sequential closing of the valve between said working chamber and said pump volume, and the open of said valve between said pump volume and said heat exchanger; \n a sequence of actions occur as the said working piston approaches and leaves TDC such that the connecting valve between said cooling exchanger and said working chamber closes instantaneously before said diaphragm (separating said pump volume and said expansion volume) is allowed to move toward closing, so said expansion volume on the bottom side of said diaphragm, as defined by the displacement movement of the said diaphragm, opens instantaneously before said inlet valve to said expansion volume opens, allowing a hot pressurized bolus of working fluid to enter the engine from said heat exchanger; \n the sequence of operations, as the working piston approaches TDC, is precise; \n the said working chamber almost completely empties into said pump volume and said cooling exchanger volume before said valve between said cooling exchanger and said working chamber closes; \n when said valve between said cooling exchanger and said working chamber closes, the diaphragm mechanism is immediately released, allowing movement of the diaphragm to close the said pump volume; \n the force acting on said diaphragm is sufficient to complete the rapid action said force at near TDC is sufficient to maintain pressure on the face of said valve between said working chamber and said pump volume so said flow through said pump to said heat exchanger is unidirectional; \n immediately after said diaphragm begins to move, the said inlet valve from said heat exchanger opens to said expansion volume, allowing the opening void in said expansion chamber to fill; and \n when said working piston approaches TDC, the diminishing volume of said working fluid in said working chamber during compression shifts from compressing into said pump volume to merging into the void being defined as said expansion chamber volume opens, ensuring that the volume at TDC is not constricted causing said working piston to jam.
