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 4):
The heat engine of  claim 1 , including an oscillation diaphragm, to define alternately the pump volume and expansion volume wherein:\n the structure of the said diaphragm has a conical frustum shape so as to optimize the structural integrity and strength of the walls of the oscillating diaphragm; the conical frustum shaped structure adds strength while decreasing the required weight of the diaphragm; the conical frustum shaped structure provides a tight configuration so as to decrease the residual dead volume of working fluid being cycled, minimizing volumetric pocket waste at the valve connections of said working cylinder and said pump chamber so the fluid cycling is more complete, compact, and efficient; said valve means between said working chamber and said pump volume that is mounted on said conical frustum shaped divider diaphragm between said working chamber to said pump volume so that fluid compression out of said working chamber to said pump volume is direct; and wherein; said valve between the working chamber and pump volumes automatically closes at near TDC due to rapid pressurization occurring inside said pump volume that is caused by the rapid closing of that said pump volume; the rapid movement of said diaphragm as said pump volume closes causes a higher pressure condition inside said pump volume, ensuring that said valve between the working chamber and pump chamber remains closed during the closing of said pump volume; a flapper plate component of the outlet valve between the said pump volume and said heat exchanger is sandwiched between the conical frustum shaped body encasement walls that enclose said pump volume, creating unidirectional flow from the pump volume to the high pressure/temperature said heat exchanger; and the inlet valve between said working chamber and said pump volume has multi-inlet openings whereas the outlet valve between said pump volume and said heat exchanger has multi-outlets around the upper parameter of the said conical frustum shaped body casement that encloses said pump volume.
