Abstract

PURPOSE: To enable automatic opening or closing depending on temperature change, by providing a slider in a nonmagnetic tube so that the slider corresponds to a stator provided outside the tube and by making one of the stator and the slider of a permanent and the other of a thermosensitive magnetic substance of prescribed Curie point.
CONSTITUTION: When the temperature of a fluid which enters through an inlet port 2 is not higher than Ta or Tb, a slider 8 made of a thermosensitive magnetic substance is magnetized so that the slider is maintained in a position shown by a full line in Fig., against a spring 11 in interaction with a stator 4 made of a permanent magnet and fixed on the peripheral part of a nonmagnetic tube 1. As a result, the fluid flows out of an outlet port 3 through the passage hole 9 of the slider 8 and the passage hole 7 of a valve seat 6. When the temperature of the fluid exceeds Tb, the slider 8 is not magnetized and brought into pressural contact with the valve seat 6 by the restoring force of the spring 11. As a result, the passage hole 7 is shut off by a valve element 10 secured on the slider 8 and the fluid flow is stopped.
