Abstract
A linear drive motor of a cryogenic refrigerator, where a reciprocating armature (10) which alternately compresses and expands a gaseous fluid in a thermodynamic cycle, is supported at both ends by flexure supports (110, 130). The armature has a clearance seal (150) with a stationary piston (11) attached at one end to the armature housing by a flexible stem (11B) to minimize cross-bearing loads between the armature and the stationary piston along the clearance seal.
