PURPOSE:To form a compressor by utilizing the magnetic field of a superconductive coil by providing a movable coil which is movable inside the superconductive coil, supplying an AC current to the coil to reciprocate a piston which is cinnected to the movable coil. CONSTITUTION:A superconductive coil 2 which is contained in a cryostat 1 is cooled to a cryogenic temperature with liquid helium from a helium tank 3, and evaporated helium is again liquefied by a refrigerator 4, to which the high pressure helium gas is supplied, and used for cooling. At this time, movable coils 6 are slidably mounted in parallel inside the coil 2 of race track state, a current is supplied from an AC power source 9 to the coil, thereby reciprocating the coil 6, a piston 7 is reciprocated in a cylinder 8 through an arm 12. Accordingly, the magnetic field of the arm 2 can be effectively used to form a compressor, thereby reducing the size. |
