Abstract

A steam iron with a valve for controlling the flow of water from a water reservoir to a steam generating chamber. The valve has a displaceable bridge-shaped member positioned outside the water reservoir and spaced apart from a shaft carrying member. A valve stem extends between the legs through the bridge-shaped member and through a contour cam attached to the top of the bridge-shaped member. The valve stem is attached to the shaft carrying member. The contour cam has a first slanted surface along its circumference upon which a shaft carrying member projection may rest. There are two bimetallic elements sensitive to predetermined temperature changes, located on the steam generating chamber and symmetrically positioned with respect to the valve stem and connected to the legs of the bridge-shaped member, such that when the bimetallic members reach a predetermined temperature, they exert upward pressure against the legs of the bridge-shaped member and raise the bridge-shaped member toward the shaft carrying member thereby permitting a flow of water from the reservoir to the steam generating chamber.
