Abstract
A high temperature sealing system for an axially expandable volume includes a piston seal whose temperature rating is lower than the operating temperature of the expandable volume. A primary backup seal includes a pair of opposing wedge-shaped rings that driven axially together against a wedge angle which drives them radially apart to close a gap and generate a torturous flow path to resist liquified piston seal material. A secondary backup seal includes a metal face seal positioned at an end of travel (EOT) stop.
