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