Stirling cycle refrigerators, Burmiya cycle refrigerators, Gifford cycle refrigerators, and Gifford McMahon cycle refrigerators are multiple low-temperature region refrigerators consisting of a compression space, a cooler, a regenerator, a heat exchanger, and an expansion space. By combining high-temperature range refrigerators such as Stirling cycle refrigerators, Gifford McMahon cycle refrigerators, Solvay cycle refrigerators, Burmiya cycle refrigerators, Claude cycle refrigerators, etc., we generate refrigeration at temperatures of approximately 5K or less. This refrigeration system is attached to a cryostat that houses a superconducting magnet cooled with liquid helium, and the helium vapor that evaporates due to the heat that enters the cryostat is liquefied again. It is used in cooling devices that keep the amount of liquid helium in a cryostat constant at all times.

For this reason, the efficiency of the entire device deteriorates, and in order to obtain the same refrigeration output in the expansion space 113 of the refrigerator in the low-temperature region, a large input is required for the entire low-temperature device, which increases the size and weight of the device. There is. This means that the compression space 112 and expansion space 113 of the refrigerator in the low temperature region are in the cylinder 11.
a piston 111 slidingly disposed within 6,117;
110, the working gas enters the gap formed between the piston and the cylinder to allow the piston to slide, and this working gas absorbs the heat carried from the normal temperature part and the heat transmitted through the piston. This is because it cannot be made small enough.

きる。(Function) The volumes of the compression space 23 and the expansion space 22 of the refrigerator 10 in the low temperature region, which are configured by the compression space 23, the heat radiation section 28, the regenerator 29, and the expansion space 22, are as follows.
The expansion space is fluctuated by the reciprocating motion of the bellows 25 and 24 linked to the power source, crankshaft, etc., and the phase difference of the fluctuation is driven so that the expansion bellows 24 advances approximately 90 degrees relative to the compression bellows 25. Refrigeration is generated at 22, and compression heat is generated at compression space 23. The compression heat and the heat that enters the compression section 23 from room temperature are absorbed by the low temperature operating gas of the refrigerator 11 in the high temperature region in the heat radiation section 28,
The above heat becomes a refrigeration load on the refrigerator in the high temperature region.
By constructing the expansion space 22 with a bellows 24, one end of which is interlocked with the heat insulating connecting member 20, and the other end fixed with a heat insulating support cylinder 26, the gap between the piston and the cylinder can be secured in a conventional piston/cylinder type refrigerator. The heat carried by the existing working gas in the expansion space is eliminated, and the conduction heat transmitted through the piston and cylinder is also reduced, so that the expansion work generated in the expansion section 22 can be effectively extracted to the outside as refrigeration output.

By interlocking one end with the heat insulating connecting member 21 and fixing the other end with the heat insulating support cylinder 27, it is possible to reduce the heat entering the compression section 23 in the same manner as the expansion space 22, and therefore, the cooling of the high temperature region The refrigeration load on the machine can be reduced.

This is performed by reciprocating the heat insulating connecting members 20 and 21 fixed to one end of the bellows 24 and 25. The connecting members 20 and 21 are fixed to one end of the expandable members 33 and 34 in the normal temperature section, which make the vacuum container 35 vacuum-tight with respect to the atmosphere. At this end, connecting rods 31 and 32 are further provided which transmit the reciprocating motion of the drive mechanism of the normal temperature section.
are fixed, and the reciprocating motion of the connecting rods 31, 32 is directly transmitted to the heat insulating connecting members 20, 21 via the expandable members 33, 34.

Since it is completely cut off from the outside by 4,
Unlike piston-cylinder type refrigerators, there is no deterioration of refrigeration efficiency due to heat intrusion from the room-temperature part, and furthermore, the lubricating oil used in the drive part or the wear powder of the sealing material of the sliding part does not deteriorate. The effect is extremely large because impurities such as these do not mix into the operating gas, and performance deterioration of the refrigerator due to contamination of the cold storage material, surface contamination of the flow path 30 in the heat dissipation section, etc. does not occur.
