Of the Stirling engine playing dexterity parts and regenerator using this

摘要

PROBLEM TO BE SOLVED: To provide a part for a regenerator of a Stirling engine and the regenerator using the same, for reducing frictional resistance when contacting, and capable of maintaining a proper gap quantity corresponding to a working fluid amount, in the Stirling engine with the cylindrical regenerator disposed around a displacer.;SOLUTION: A part 10 for a regenerator of a Stirling engine includes a hollow disk-like metallic thin plate 11 and a comb-teeth part 12 formed along the inner edge of the metallic thin plate 11. Respective comb-teeth 14 of the comb-teeth part 12 are curved so as not to turn to the center of the metallic thin plate 11. The metallic thin plate 11 has a stepped part 16 for forming a thickness on its outer edge side thicker than a thickness on the inner edge side. The regenerator 40 of the Stirling engine is constituted by laminating the parts 10 for the regenerator.;COPYRIGHT: (C)2013,JPO&INPIT
