Abstract:
1. A sliding element for providing a seal between sliding faces of a pair of relatively slidable components, one of said components being a stationary sliding element and the other of said components being a rotary sliding element, said sliding faces retaining a plurality of elongate dimples in an inner circumferential side and an outer circumferential side with respect to a boundary reference line, said dimples disposed in said inner circumferential side being inclined toward a different direction from said dimples in said outer circumferential side, forward edges of said dimples relative to a rotational direction disposed in said outer circumferential side being inclined toward said outer circumference, forward edges of said dimples relative to the rotational direction disposed in said inner circumferential side being inclined toward said inner circumference, a plurality of radial lines, said dimples located in said outer circumferential side and said inner circumferential side being disposed along a radial line of said plurality of radial lines, said plurality of said radial lines being disposed along a circumferential direction in a radicalized manner, and along each radial line of said plurality of radial lines, at least two dimples in said inner circumferential side and at least two dimples in said outer circumferential side are arranged to form a plurality of circles of dimples in each of said inner and outer circumferential sides.
