ABSTRACT:
A permanent magnet armature is reciprocated between electromagnetic coil assemblies in a motor chamber that is evacuated and maintained at a cryogenic temperature by circulation of a cryogenic cooling medium through pressure sealed, coil enclosing spaces of the coil assemblies. Shock absorbers absorb the thrust applied by the armature to the coil assemblies at the ends of its stroke. The armature drives pumps for transmitting motive energy externally of an insulated enclosure within which the power plant is housed.
