Abstract

A combustor for use in an external combustion engine having a rotary-type regenerator heat exchanger includes a housing having a combustion chamber, an air chamber, a plurality of first outlet ports, and a first inlet port. A main partition defining the combustion chamber and the air chamber in the housing has a plurality of second outlet ports defined in a peripheral portion thereof and a second inlet port defined in a central portion thereof. An annular regenerator is rotatably supported in the housing, dividing the air chamber into first and second chambers, the regenerator having first and second axially opposite end surfaces and a multiplicity of axial through-holes extending therebetween. First subpartitions define first outlet passages communicating between the first outlet ports, respectively, and the first end surface of the regenerator, and divide the first chamber into air and exhaust sections. Second subpartitions define second outlet passages communicating between the second outlet ports, respectively, and the second end surface of the regenerator, and divide the second chamber into air and exhaust sections.
