部分を示す。 FIG. 1 is a diagram showing a refrigerator according to an embodiment of the invention, FIG. 2 is a diagram showing an example of a conventional refrigerator, FIGS. 3 to 3 are diagrams showing the operation of a conventional refrigerator, and FIG.
The figure is a diagram showing the relationship between the gas pressure in the gas spring space, the gas pressure in the working space, and the displacement of the moving body. In the figure, 1 is a compressor, 2 is a cold finger, 5 is a supply pipe, 7 is a moving body, 10 is a heat exchanger, 20 is an elastic body, 21 is a gas hole, and 22 is a moving body cap. The same reference numerals in the figures indicate the same or corresponding parts.

Claims

[Scope of utility model registration request]

The cold finger section consists of a compressor that causes periodic pressure fluctuations in the working gas in the 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. is a cylindrical cylinder,
a movable body cap that reciprocates inside the cylinder and holds down a movable body having a heat exchanger therein and a heat exchanger housed in the movable body from one end of the movable body; Seal a portion of the pipe connected to one end located within the sleeve and an internal cylinder that defines the moving direction of the moving body, and which absorbs heat from the outside of the working space surrounded by the moving body and cylinder. The movable body is a gas operating space, the movable body having a seal for a movable body, a gas spring space located in the internal cylinder and surrounding one end of the movable body, and a seal for a piston member that separates the gas spring space from the pipe space. driven by the differential pressure between and the gas spring space,
In a refrigerator in which there is a phase relationship between the pressure in a working space supported by an elastic body and the motion of a moving body, a gas hole formed in the moving body cap through which working gas passes is tapered. A refrigerator characterized by:
