Abstract

PURPOSE: To enhance the safety of a thermal cock which opens or closes a fluid passage by a thermosensitive element, by automatically shutting off the fluid passage when electricity supply to a heating element for heating the thermosensitve element is suspended or ceased.
CONSTITUTION: An operating shaft 4 is extended from a valve 1 which opens or closes the fluid passage 2 of the body 3 of a cock. A driving section is coupled to the shaft 4. The driving section comprises a thermosensitive driver 5, a heater including a power switch 6 and a PTC heating element 7 for heating the driver, and a crank mechanism 8. One end of a return spring 12 is engaged with the link 11 of the crank mechanism 8. When electricity supply to the PTC heating element 7 is suspended or ceased by the spring 12 because of a trouble such as power outage, the valve 1 is returned to a position to shut off the fluid passage 2.
