Abstract
A seal assembly includes a semi-tubular sealing element defining a longitudinal axis, and a retainer configured to retain the sealing element. The sealing element has a longitudinal center portion and first and second longitudinal side portions, an array of resilient arcuate fingers extending from the first longitudinal side portion and curving partially around the longitudinal axis, and a depressor portion extending from the second longitudinal side portion and having a free edge diametrically opposed to the center portion. The retainer defines a channel with an entrance opening, the channel being configured to receive the sealing element in a position in which the depressor portion extends outside of the entrance opening in position to bear a load, the channel being defined by a pair of opposed side walls configured to resiliently capture the sealing element.
