Embodiment Construction

[0025] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in the following description, the same code|symbol is attached|subjected to the same element, and repeated description is abbreviate|omitted suitably. In addition, the structures described below are only examples and do not limit the scope of the present invention in any way.

[0026] figure 1 It is a figure which schematically shows the whole structure of the cryogenic refrigerator 10 which concerns on one Embodiment of this invention. The cryogenic refrigerator 10 includes a compressor 11 , a flexible connecting pipe 12 , and an expander 13 . The compressor 11 and the expander 13 are arranged separately. The flexible connecting pipe 12 connects the working gas chamber of the compressor 11 to the working gas chamber of the expander 13 . The flexible connecting pipe 12 constitutes a gas flow path through which working gas flows between the compr...

Abstract

Provided is a flexible connection pipe for a very low-temperature refrigerator, said connection pipe preventing or alleviating a deterioration in the performance of a very low-temperature refrigerator. This flexible connection pipe (12) for a very low-temperature refrigerator is provided with: a connection hose (14) that is provided with a flexible pipe (18), which has a pipe end (22), and a flexible tube (20), which has a tube end (24) being adhered to the pipe end (22) and is inserted into the flexible pipe (18); and a connection adapter (16) for connecting the connection hose (14) to a component of the very low-temperature refrigerator, said connection adapter (16) being adjacent to the tube end (24) and being fixed to the pipe end (22).

Description

technical field [0001] The invention relates to a flexible connecting pipe for an ultra-low temperature refrigerator and an ultra-low temperature refrigerator with the flexible connecting pipe. Background technique [0002] In a conventional cryogenic refrigerator, one component and another component (for example, a compressor and an expander) are connected by hard tubes. This structure is effective in reducing pressure loss in the connecting pipe. However, since the hard tube is difficult to change its shape, it is difficult to freely change the relative positions of the constituent elements. Therefore, the installation layout of the site where the refrigerator is used is limited. Therefore, in order to increase the degree of freedom of installation, it has been proposed to use a flexible tube for the refrigerator. The flexible tubing also helps reduce the transmission of vibrations between the components of the refrigerator. [0003] Previous technical literature [0...
