LINEAR MOTOR COMPRESSOR WITH STATIONARY PISTON Abstract of the Disclosure A linear motor compressor within a cryogenic refrigerator wherein the compressor space, within which a gaseous flud is alternately compressed and expanded, is formed by a stationary piston (11) and a reciprocating armature (10) that is concentric about the piston. The armature is supported along a clearance seal with the stationary piston. An axial bore (14) along the stationary piston conveys gaseous fluid from the compression space (24) to a displacer within the cold finger of the cryogenic refrigerator. An isolator for reducing transmission into and out of the compressor comprising a dynamic absorber (40) and flat springs (61, 71) mounted with a damping material (95, 96) between the compressor and a mounting frame. A sensor (80) for detecting the position of the armature utilizes a target magnet (81) whose magnetic flux lines are decoupled from the flux lines generated about the coil.
