  • High-temperature thermal actuator utilizing phase change material
    Patent number: 10047730
    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 RbNO3 and CsNO3 in precise proportion that provides operation within this range.
