ABSTRACT:
The temperature responsive valve device controls a fluid passage within a valve body by opening a valve member at a low temperature, closing the valve member at an intermediate temperature and re-opening the valve member at a higher temperature. The valve member is controlled by two bimetal discs each of which is adapted to snap over center at differently selected temperatures and springs associated with the valve member and one of the bimetal discs respectively.
