Abstract: A temperature responsive valve includes a housing and a cylindrical structure disposed within the housing. The housing defines an inlet passageway and an outlet passageway wherein the cylinder body of the cylindrical structure is disposed between the inlet passageway and the outlet passageway. The cylindrical structure includes a first layer so that the cylindrical structure is configured to expand from a decreased diameter to an increased diameter when the first layer of the cylindrical structure is exposed to an increased pre-determined temperature range causing the cylindrical structure restricts the inlet passageway and the outlet passageway at such increased pre-determined temperature range.
