Title:
軸整合したコンポーネントを有するパルスチューブクライオクーラー
Document Type and Number:
Japanese Patent JP6987222
Kind Code:
B2
Abstract:
A pulse-tube cryocooler includes a compressor piston that is axially aligned with a pulse tube. The compressor piston is an annular piston that has a central hole around its axis. An inertance tube, connected to one end of the pulse tube, runs through the central hole in the compressor piston. The cryocooler also includes a balancer that moves in opposition to the compressor piston, to offset the forces in moving the compressor piston. The balancer may also be axially aligned with the pulse tube, the annular piston, and the inertance tube. The alignment of the compressor piston, the pulse tube, and the inertance tube aligns the forces produced by movement of fluid within the cryocooler.
