ラバネを設けたことを特徴とする冷凍機。 It consists of a compressor that causes periodic pressure fluctuations in the working gas in a working space, and a cold finger section that communicates with the working space of the compressor via a supply pipe and that absorbs heat from the outside at one end. The part includes a cylindrical cylinder, a moving body that reciprocates inside the cylinder,
a seal for the moving body that surrounds the moving body and seals a portion where the supply pipe is connected to one end that absorbs heat from the outside of the working space surrounded by the moving body and the cylinder; and a gas that surrounds one end of the moving body. The movable body has an inner cylinder fitted with a spring space and a piston member seal for sealing a portion where the gas spring space and the supply pipe are connected, and the movable body is configured to prevent a difference between the gas working space and the gas spring space. driven by dynamic pressure;
The refrigerator has a phase relationship between the pressure in the working space and the motion of the moving body, characterized in that the refrigerator is provided with a spring that presses and fixes the internal cylinder against the cylinder.
