摘要: A linear drive motor of a cryogenic refrigerator, where reciprocating armature is coupled to piston which alternately compresses and expands gaseous fluid in thermodynamic cycle. The has clearance seal attached at one end flexible coupling reduce cross-bearing loads exerted by the along seal. displacer assembly refrigerator employs that reciprocates cylinder and/or reduces radial forces on
