Abstract
A temperature-responsive actuator for a sealing assembly comprises first and second annular members each having a camming surface for engagement with one another, the first and second annular members being positioned against each other so that they are nested and together exhibit a height 'h' at ambient temperatures, the first annular member having a coefficient of thermal contraction less than the coefficient of thermal contraction of the second annular member so that when the thermal actuator is subjected to temperatures less than ambient temperatures, the first and second annular members contract different amounts such that the 'effective' height of the actuator becomes 'h+.tangle-solidup.h'.
