Abstract
Disclosed is a high-temperature thermal actuator that utilizes the dimensional change of a phase change media hermetically sealed within a shell. This actuator regulates and controls flow of a fluid between an intake and an exhaust utilizing a valve. In one example, the disclosed embodiments operate in temperature range between 350° C. and 400° C. This actuation range is tailored for specific applications utilizing an exemplary combination of RbNOand CsNOin precise proportion that provides operation within this range.
