ABSTRACT:
A heat recuperative engine is provided with an improved heat recuperator having two branches. Each branch houses a pair of meshed gearlike rotors that extend across the chamber of the housing to form a blockage between the inlet and outport ports of the chamber. The rotors are formed similarly to external spur gears and have a central cylindrical body bearing radially projecting teeth or lobes which mesh to form a sealing line of contact that maintains the blockage when the rotors turn. Each rotor of the pair has its projecting teeth or lobes fitting closely with a segment of the chamber wall in which an array of heat pipes is embedded. The spaces between adjacent lobes of a rotor provide constant volume enclosures as the lobes sweep around the closely fitting chamber wall segment and carry working medium from the inlet to the outlet side of the chamber. The heat pipes extend between the two branches so that the hotter working medium swept around by the rotors in one branch gives up heat to the heat pipes which transfer that heat to the cooler working medium swept around by the rotors in the other branch. Consequently, the working medium in one branch is cooled while it is confined in moving constant volume enclosures and the working medium in the other branch is heated while it is confined in moving constant volume enclosures.
