Abstract

PURPOSE: To enable always optimal valve opening/closing control, by moving a valve plate on a plane which extends across the flowing direction of a fluid and by driving the valve plate by the magnetic force of a magnet while controlling its magnetic flux depending on temperature change.
CONSTITUTION: When the temperature of a thermosensitive magnetic member 32 thrusted on a bar 27 of soft magnetic substance and housed in an opening provided in a projection of a housing 10 is lower than the Curie point, the magnetic flux of a permanent magnet 31 is bypassed through the member 32 being in a ferromagnetic state. As a result, the magnetic force of the permanent magnet 31 scarcely acts to a valve plate 22 of ferromagnetic substance and the plate is retained in a position by the force of a spring 24 to shut off the through holes 17, 18 of a valve seat plate 19. When the temperature of the thermosensitive magnetic member 32 exceeds the Curie point, the member becomes paramagnetic. As a result, the magnetic flux of the permanent magnet 31 flows through the bar 27 of soft magnetic substance and the valve plate 22 is moved rightward against the force of the spring 24 to start fluid flow.
