CRYOGENIC REFRIGERATOR |
| 摘要 |
In a cryogenic refrigerator, a displacer includes a cover portion at a low temperature end of the displacer. A cylinder accommodates the displacer to be reciprocated in a longitudinal direction and forms an expansion space of a refrigerant gas between the cover portion and the cylinder. A refrigerant gas channel through which the displacer and the expansion space communicate with each other is formed in the cover portion. In the refrigerant gas channel, a flowing-out direction of the refrigerant gas flowing into the expansion space is inclined with respect to the longitudinal direction of the displacer. |

1. A cryogenic refrigerator comprising:
a displacer; a cover portion which is provided on a low temperature end of the displacer; and a cylinder which accommodates the displacer to be reciprocated in a longitudinal direction and to form an expansion space of a refrigerant gas between the cover portion and the cylinder, wherein a refrigerant gas channel, through which the displacer and the expansion space communicate with each other, is formed in the cover portion, and wherein a flowing-out direction of the refrigerant gas flowing into the expansion space is inclined with respect to the longitudinal direction of the displacer in the refrigerant gas channel. |
