Abstract

A high temperature dynamic seal and methods of assembly and use. The dynamic seal is provided as a rotating seal, which includes a stationary ring and rotating ring assembly, with a seal ring that is positioned between the stationary ring member and the rotating ring assembly. One or more high temperature seals create a seal between the stationary ring member and a device in which the dynamic seal is used. Similarly one or more high temperature seals create a seal between the rotating ring assembly and a rotating shaft of the device. One or more of the high temperature seals are formed from a metallic material with various cross-sectional shapes.
