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 9):
The heat engine of  claim 1 , further comprising a near adiabatic engine with means of preventing or accommodating leakages, wherein:\n a means of sealing from leakage around the rim of said diaphragm separating said expansion chamber and said pump volume by using a parameter bellows seal; a means of sealing from leakage along the diaphragm rod between the pump interior volume and the outside atmosphere by using a bellows seal; a means of preventing leakage between said working piston and crankcase by using a bellows seal; a means of minimizing wear and tear on said bellows seal between said working piston and said crankcase by sufficiently elongating said bellows (relative to the travel of the said working piston); a means of handling said wear and tear of the rapid oscillating movement of said bellows while eliminating friction by using a resilient material, such as spring steel; a means for returning the leaking fluid back into the cycling volumes of the engine instead of using a said bellows seal to prevent leakage around the main working cylinder or cylinders; said means of returning said leaked fluid to said cooling exchanger sink for recycling, when pressure in said cooling exchanger at its lowest pressure/temperature point in the cycle; and said means, when said working fluid seeping into said crankcase, may flow back from said crankcase to said cooling exchanger sink due to the pressure differential between said crankcase and said cooling exchanger sink, returning said leaked working fluid to the cycling volumes through a unidirectional check valve placed between said crankcase and said cooling exchanger.
