Document Type and Number:
Japanese Patent JP2003075005
Kind Code:
A
Abstract:
To prevent the fall of the refrigerating capacity of a Stirling refrigerating machine by preventing heat losses by interrupting the heat transfer caused by the movement of a working medium by interrupting the entrance and exit of the working medium in and from the piston and cylinder of the Stirling refrigerating machine and the movement of the medium in the piston.
Even when a gap is produced in the screw-fit section 36 between a dome 33 and a metallic piston main body section 34, both of which constitute the piston 21, and the working medium flows in and out between the cylinder and piston 21 through the gap, the flow of the working medium in the piston 21 is interrupted by providing a heat shielding members 41-43 in the piston 21.
