PURPOSE:To improve the thermal efficiency and durability, by a method wherein a high temperature cylinder and a reproducer housing part are formed integrally with each other to form a dome-shaped cylinder, and an inner liner, partitioning a reproducer chamber and an expansion chamber, is situated to the interior of the cylinder. CONSTITUTION:A dome-shaped cylinder containing a high temperature cylinder and a reproducer housing part is provided. An inner liner 16, partitioning a reproducer chamber and an expansion chamber, is provided, and its top part is engaged with the internal peripheral surface of the top part of the cylinder 15, its lower part being engaged with the upper part of a cooler 6. A reproducer filler (reproducer) 5 is situated between the cylinder 15 and the inner liner 16, and a concentric annular cooler 6, having it sinner wall surface forming a surface sliding over a displacer, is located below the reproducer 5 and within the cylinder 15. In which case, projections 106 are provided in plural spots in the direction of periphery on the bottom of a cooler 6, and each projection 106 having its protruding surface formed flush with a seal ring slide surface 107 of the displacer. |
