Abstract
The present disclosure relates generally to a sliding seal between two components. The sliding seal includes a first seal section, a second seal section, and (in some embodiments) a third seal section. Two or three of the seal sections are uncoupled, which allows the uncoupled seal sections to move relative to one another during relative movement between the two components. One or more spring tabs extend from the second seal section and bias the first and third (or in some embodiments, the first and second) seal sections away from one another.
