Abstract
A thermally sensitive check valve is disclosed in which a bimetallic snap disc functions in one position as the check valve element and in another position to either maintain the valve open as in one illustrated embodiment, or to maintain the valve closed as illustrated in another embodiment. By combining the check valve function and the valving function in a single bimetallic snap disc, a simple and reliable device is provided.
