ABSTRACT:
There is disclosed an apparatus and method for a thermosensitive safety valve to restrict a supply of fluid in a fluid delivery system when the temperature of the fluid reaches a predetermined temperature. A bimetal reed is utilized in which its unattached portion flexes outward from its normal, non-flexed position when the fluid temperature reaches a predetermined value into a flexed intermediate position with the mainstream of the fluid flow subsequently providing the pressing force for placing the unattached portion in a fluid restricting position. Furthermore, the reed may be reinstated in at least its flexed intermediate position so as to allow for subsequent fluid flow when the temperature of the same has been adjusted to a value less than the predetermined value of temperature.
