ABSTRACT:
A seal for a joint subjected to oscillatory motion having a W-shaped seal ring in an unloading condition which encompasses a load ring. The W-shaped seal ring comprises a driving flange, a sealing flange and a bight portion interconnecting the two flanges. The load ring is adapted to be fitted in the seal ring to force the driving flange into an interference fit with the counterbore walls so as to cause the driving torque to be applied through the seal ring. The thickness of the driving flange and the bight portion is made substantially same so as to ensure enough rigidity in the radial direction while allowing the seal ring to deform readily in the axial direction.
