Claims (1)
ンサイクル等の冷凍サイクルを使用した蓄冷器式
小型冷凍機において、ヘリウムガス等の冷媒を断
熱膨張させる寒冷発生空間を構成するシリンダー
部とデイスプレーサー部とのすきま部の気密を保
持するためのデイスプレーサー部の高温端、低温
端にそれぞれ１個以上のシールを設けたことを特
徴とする蓄冷器式小型冷凍機。 In a regenerator type small refrigerator using a refrigeration cycle such as a Stirling cycle or a Gifford-McMahon cycle, the gap between the cylinder part and the displacer part, which constitutes the cold generation space where a refrigerant such as helium gas is adiabatically expanded, is airtight. A regenerator-type small refrigerator characterized by having one or more seals provided at each of the high-temperature end and the low-temperature end of the displacer section for holding the temperature.
