Abstract

See full text

Thermally activated devices, including thermally activated release devices. These devices may be used as part of any device or system in which thermal activation may be desired. In particular, described herein are thermally activated devices configured as sprinkler valves. The thermally activated devices typically include a channel and a plug element, where the plug element is a shape memory material, which may be a single-crystal shape memory alloy. The channel has two connected regions, where the first region has a diameter that is greater than the diameter of a plug element in a first configuration and the second region has a diameter that is less than the diameter of the plug element in the first configuration but greater than the diameter of the plug element in its second configuration.
