<p>The invention relates generally to the technical field of a sliding element (1) engaging a relative rotational motion and is such as to decrease a friction coefficient of a sliding face (2) and to improve the seal performance. The element has dimples (3) on at least one sliding face (2) of a pair of relatively rotating sliding faces (2,2), wherein the dimples (3) are inclined towards a rotary direction when viewed along a radial direction. The sliding face (2) of the sliding element (1) also disposes a plurality of ring-formed dimple sections (3A, 3B, 3C ...), which form annuli of distinct diameters wherein the dimples (3) are arranged along the individual annuli. The sliding face (2) also disposes annular dam sections (2A) which are located between the individual dimple sections (3A, 3B, 3C ...). <IMAGE></p> |
