A seal assembly

A sprung seal assembly (20) includes a flexible sprung seal (22) having a center section (24) disposed between opposing curved and cantilevered first and second end sections (26, 28). First and second free edges (30, 32) of the first and second end sections (26, 28) respectively are trapped within a retainer (36). First and second sliding lugs (40, 42) attached to the first and second free edges (30, 32) respectively are slidably disposed in first and second channels (50, 52) respectively. The first and second free edges (30, 32) are trapped in the retainer (36) by the first and second sliding lugs (40, 42) disposed in the first and second channels (50, 52) between a mounting surface (60) and the retainer (36) attached to the mounting surface (60). The center section (24) may have a wear strip (66). The sprung seal assembly (20) may be disposed between a relatively fixed sidewall (11) and a relatively movable flap (13) of a nozzle assembly (8). The retainer (36) is mounted to the flap (13) and the center section (24) is in sealing engagement with a sealing surface of the sidewall (11).
