Claims (1)
よび、前記膨張ピストンが往復動可能に装架され
、前記膨張ピストンの先端部との間に膨張空間を
画成する膨張シリンダを備え、前記蓄熱部が前記
膨張ピストン外周に刻設された環状溝を介して前
記膨張空間と連通する極低温冷凍機において、前
記環状溝よりも先端側に位置すべくシール部材を
前記膨張ピストン外周に嵌装し、常時前記膨張空
間および常時前記環状溝と夫々連通する開口を備
えた熱交換器を前記膨張シリンダの先端部外周に
配設した極低温冷凍機。 an expansion piston having a heat storage section built therein; and an expansion cylinder on which the expansion piston is mounted so as to be able to reciprocate and define an expansion space between the expansion piston and a distal end of the expansion piston. In a cryogenic refrigerator that communicates with the expansion space via an annular groove carved on the outer periphery of the expansion piston, a sealing member is fitted on the outer periphery of the expansion piston so as to be located on the distal side of the annular groove, and the sealing member is always placed on the outer periphery of the expansion piston. A cryogenic refrigerator comprising: a heat exchanger having openings that communicate with the expansion space and the annular groove at all times, and disposed on the outer periphery of the distal end of the expansion cylinder.
