选择在低温下产生少量制冷的最佳方案的演变过程导致容积式往复膨胀机成为最广泛使用的装置。这些机器在斯特林循环、Gifford-McMahon循环、Solvay循环、Vuilleumier循环或这些循环之一的一些修改上操作。无一例外，今天在这些循环上建造的机器都使用长膨胀机活塞，该活塞将冷区域与环境温度分开，并允许重要的活塞密封件位于环境温度下。
The evolutionary process of selecting the best scheme of producing small amounts of refrigeration at cryogenic temperatures has resulted in positive-displacement reciprocating expanders becoming the most widely used means. These machines operate on the Stirling cycle, Gifford-McMahon cycle, Solvay cycle, Vuilleumier cycle, or some modification of one of these. Without exception, the machines being built today on these cycles all use a long expander piston which separates the cold region from ambient temperatures and permits the important piston seal to be located at ambient temperature.
