ABSTRACT:
A sealed joint between two relatively movable surfaces. There is a recess in a first surface and a sealing member is received in with a close fit in the recess. The sealing member has a modulus of elasticity such that it does not deform substantially under a predetermined external pressure. The sealing member extends from the recess to contact the second surface. A sealing ring is received in the recess to provide an additional seal for the joint. Pressure applied to one side of the joint can act on that side of the sealing member remote from the second surface to force the sealing member against the second surface. The end of a sealing member is chamfered where it contacts the second surface to reduce the area of contact with the second surface.
