SUPERCONDUCTION NON-CONTACT COMPRESSION EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a high efficiency actuation gas compression device capable of performing continuous compression for a long period of time under an extra low temperature condition. ! SOLUTION: This invention is constituted by a magnetic levitation mechanism comprising ferromagnetic permanent magnets 38 stored in a piston 14, cryostat 34 arranged outside a cylinder 12 so as to oppositely face against the permanent magnets 38, a plurality of magnetic floating formations 32 stored inside the cryostat 34 and constituted by a bulk super conductive member 36 cooled down to a degree less than superconductive transition temperature arranged in an axial direction of the piston 14; a linear driving mechanism 24 comprising permanent magnets 26 stored in the piston 14 and arranged to show different polarities in a cylinder axial direction and a plurality of electromagnets 28 arranged in the cylinder 12 so as to face against the permanent magnets 26 and to show different polarities alternatively in an a
