ABSTRACT:
A fluid delivery control device for regulating fluid delivery by a pump to the heated vaporization chamber of a steam curling iron through a fluid conduit provided with a spring biased valve in response to the temperature of a heating element in the chamber includes a bimetallic disc in the chamber having the property of changing its shape when heated to a temperature corresponding to the minimum temperature required of the heating element for vaporizing the fluid. A fluid delivery tube through which the fluid is delivered from conduit to the chamber has one end adjacent to the valve and the other end attached to the disc for movement therewith. When the chamber is below the minimum temperature, the disc pushes the one end of the tube against the valve to hold it closed and prevent delivery of fluid through the tube to the chamber. When the chamber is at or above the minimum temperature, the disc distorts and pulls the tube away from the valve, allowing the valve to be opened and fluid to be delivered through the tube to the chamber.
