PURPOSE:To rapidly operate at a specified temperature by securing a fixed side magnet around a nonmagnetic guide tube and a thermo-sensitive magnetic element at one opening end of the guide tube, and movably inserting a movable side magnet along the inside of the tube. CONSTITUTION:A fixed side permanent magnet 2 is secured around a guide tube 1 whose one opening end is provided with a yoke 3, the permanent magnet 2 is surrounded by a yoke 4, the opening end of which being secured to the yoke 3. A thermo-sensitive magnetic element 5 is secured within one opening end of the guide tube 1. A movable side permanent magnet 6 is movably inserted along the hollow portion of the guide tube. Since this permanent magnet 6 is tubular the thermo-sensitive magnet element 5 can be inserted into its hollow portion. |
