摘要：In this sealing device comprising at least one sealing ring (6) placed in a circular groove (2), a first ring (6) is provided which is located close to the bottom of the circular groove (2) and which has a width, measured in the axial direction, almost equal to the width of the said circular groove, and second and third rings (7 and 8) which are located axially side by side in the groove (2) in contact with that of the two peripheral surfaces of the first ring (6) which is the furthest from the bottom of the groove, and which have dimensions, measured in the axial direction, such that their sum is almost equal to the width of the said groove, the cuts (cut zones) in the first, second and third rings (6, 7 and 8) being angularly mutually offset. <IMAGE>
