초록

A temperature sensitive valve in which the annular valve seat is made of a thermal sensitive magnetic material having a Curie temperature that is of a preselected value. A vertically movable valve plug is positioned below the valve seat and contains a permanent magnet which normally urges the plug up into the valve seat to close the valve, but which allows the valve to open when the temperature of the valve seat exceeds the Curie temperature.

청구항

A thermally operated valve comprising a valve body having a fluid passage, a valve seat in the passage, the value seat being made of magnetic material having a predetermined Curie temperature above which the magnetic material is paramagnetic, a movable valve plug including a permanent magnet positioned in the passage, means guiding the plug into and out of engagement with the valve seat for closing and opening the plug, the magnet holding the plug against the valve seat by magnetic attraction at temperatures below the Curie temperature of the magnetic ma...
