<p>A sealing ring structure for effecting a fluid seal between a couple of members (5, 8) one of which (8) is movable with respect to the other, comprises an outer annular stressing section (3) radially biasing against a concentric inner sealing section (2) along an outer surface (6) thereof, which is provided with at least a portion inclined with respect to a direction parallel to the axis (II-II) of the movable member (8). Such configuration of the sealing section (2) is apt to assure in every operative conditions, which may occur in practice, a proper extent of the contact surface (15) avoiding leakage problems. <IMAGE></p> |
