摘要： PURPOSE:To reduce the thermal loss and to improve the engine efficiency by installing rings to seal the clearances between cylinders in which an operating gas is sealed, and pistons to partition the inside of the cylinders into two chambers of different temperatures, to the cylinders. CONSTITUTION:In a hot gas engine using a VM(Vuilleumier) cycle, pistons 1a and 1b to partition a high temperature chamber 10a and a middle temperature chamber 10b, and, a low temperature chamber 11a and a middle temperature chamber 11b, are provided respectively in a high temperature side cylinder 10 and a low temperature side cylinder 11 arranged in the square direction of an external combustion type engine 6, and at the clearances 2a and 2b of both chambers, rings 3a and rings 3b are provided in two steps respectively. In this case, the rings 3a and 3b are inserted and installed in ring grooves 4a and ring grooves 4b engraved at the upper parts of the cylinder inner walls 10c and 11c respectively. As a result, even though the pistons 1a and 1b perform reciprocating movement in the engine, the positions to partition two chambers of different temperatures are not changed, and a thermal loss flowing through the clearances and through the cylinder walls are reduced.

摘要： PROBLEM TO BE SOLVED: To reduce heat loss of heat carrying medium in a bellows 24 caused by atmosphere between a casing 22 and the bellows 24. SOLUTION: A regenerator 25 is provided between a drive shaft 27 and the casing 22 through bearings 18. The regenerator 25 is formed by forming metal such as stainless steel and brass in the form of a mesh sheet or wool. A chamber in the casing 22 is parted to a room side space RB and a heat sink side space RA. Heat of the atmosphere flowing between these is accumulated and regenerated by the regenerator 25. Temperature change in the atmosphere in the heat sink side space RA is thus restricted, thereby heat loss of the heat carrying medium in the bellows 24 is reduced. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To manufacture a regenerator for an external combustion engine, which reduces a material cost. SOLUTION: In an external combustion engine using a regeneration cycle, a cylindrical regenerator has an annular heat accumulation body 19a constituted in such a manner to combine together a plurality of notched annular materials 19a1-19a3. In this case, it is desirable that by deviating the notched annular heat accumulation elements 19a1-19a3 at every given layer in a given angle arc, joint lines in a lamination direction are differed from each other. Further, it is desirable that by effecting diffusion joining of the annular heat accumulation bodies laminated in given layers, a cylindrical regenerator is formed as a sintered product. Further, any one of a wire netting substance, a foam metal, and metallic fiber can be used as a material for each heat accumulation body.
