ABSTRACT:
A seal assembly 74 used between two members 42, 45 which are capable of relative movement is disclosed. Various construction details are developed which enable the seal assembly to accommodate other movement in a direction perpendicular to the direction of movement while accommodating movement in the direction of movement. In one embodiment, the seal assembly extends between two circumferentially extending surfaces which face each other. The seal assembly is formed of a plurality of circumferentially spaced seal elements 74 having flaps 116 which are radially and circumferentially flexible but relatively stiff in the axial direction in comparison to the radial and circumferential flexibility.
