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 12):
The heat engine of  claim 1 , further comprising a near adiabatic engine with means of preventing engine lockage, wherein:\n a shutoff valve prevents flow of fluid from said heat exchanger to said engine, preventing an equalization of pressures in said engine when idle, preventing flooding of said engine; an open channel bridge valve connects said expansion chamber and said pump chamber volumes when said engine stops, allowing an artificial balance of pressure in the environment surrounding the oscillating said diaphragm between said expansion chamber and said pump during the engine startup; said bridge valve will gradually close as said engine establishes adequate pressure/temperature separation and balances the pressure environment surrounding the oscillating said diaphragm so said engine can run on its own; and said inlet valve between said expansion chamber and said pump volume may serve in place of said bridge valve for said startup of said engine.
