Abstract

An actuator for performing a function at a predetermined temperature includes an actuator assembly with a resiliently expandable element and a device for liberating hydrogen gas into a sealed system formed in part by the element. When the hydrogen gas pressure in the system becomes sufficiently high, the element expands to perform the function. The resiliently expandable element is a piston or a bellows and the device for liberating hydrogen gas is a hydride sensor assembly.
