ABSTRACT:
A sealing ring structure for effecting a fluid seal between a stationary member having an annular groove and a cylindrical member having a longitudinal axis movable relative to the groove includes a sealing ring disposed in the groove along with an outer annular stressing member disposed radially outwardly of the sealing ring and biasing the sealing ring into engagement with the cylindrical member. The sealing ring has an end surface facing a low pressure side of the groove and an outer surface in contact with the stressing member. The end surface and the outer surface intersect to form an edge in circular line contact with the low pressure side of the groove. The end surface is inclined toward a high pressure side of the groove with respect to a line perpendicular to the axis of the movable member and the outer surface is inclined with respect to a direction parallel to the axis of the movable member.
