ABSTRACT:
A thermally responsive by-pass valve device which permits maximum fluid flow in limited area conditions. The valve device is adapted to be employed in an environment in which there are limited area conditions within conduit structure having a plurality of flow passages in a by-pass type of cooling system of an internal combustion engine. The by-pass valve device is provided with valve seat structure which has an entrance opening and an exit opening, and there is an internal wall surface of gradually increasing dimensions between the exit opening to the entrance opening. Thermally responsive actuator mechanism is positioned within the openings of the valve seat structure. The portions of the actuator mechanism which occupy the greatest area are positioned in lateral alignment with the portion of the internal wall surface having the greatest dimension, and the portions of the actuator mechanism which are of a lesser area are positioned in lateral alignment with the portion of the internal wall surface having a lesser dimension. Thus, there is minimum restriction and maximum flow area through the valve seat structure.
