摘要： By randomly arranging dimples provided on a sealing face, a sliding characteristic is improved in a wide range of a bearing characteristic number on the sealing face. A pair of sliding parts in which a plurality of dimples is arranged on at least one of sealing faces that relatively slide on each other is characterized in that each of the plurality of dimples is provided independently from the other dimples, and arranged in such a manner that the plurality of dimples having different opening diameters is randomly distributed.

摘要： Sliding parts by which a sealing function of the sealing faces can be maintained for a long time by actively taking a fluid into sealing faces and discharging the fluid from the sealing faces while meeting contradictory conditions of sealing and lubrication so as to prevent concentration of sediment causative substances on the sealing faces and hence prevent generation of sediment are provided. A fluid circulation groove 10 including an inlet section 10a where a fluid comes in from a high pressure fluid side, an outlet section 10b where the fluid goes out to the high pressure fluid side, and a communication section 10c that provides communication between the inlet section and the outlet section is provided in at least one of sealing faces of a pair of sliding parts that slide on each other. The fluid circulation groove 10 is isolated from a low pressure fluid side by a land section R. A section of a bottom wall of the fluid circulation groove 10 is formed in a round bottom shape.

摘要： A fluid is actively taken into sealing faces and discharged from the sealing faces so as to prevent concentration of sediment causative substances on the sealing faces and hence prevent generation of sediment while preventing leakage of the fluid taken into the sealing faces to a low pressure fluid side. Thereby, a sealing function of the sealing faces is maintained for a long time. A fluid circulation groove 10 including an inlet side section 11 where the fluid comes in from a high pressure fluid side and an outlet side section 12 where the fluid goes out to the high pressure fluid side is provided in one of sealing faces S of a pair of sliding parts that slide on each other. The fluid circulation groove 10 is isolated from the low pressure fluid side by a land section R. Groove width of the outlet side section 12 of the fluid circulation groove 10 is gradually expended toward an outlet end.
摘要翻译： 流体积极地进入密封面并从密封面排出，以防止密封面上的沉积物致因物质的浓缩，因此防止沉积物的产生，同时防止进入密封面的流体泄漏到低压流体侧 。 由此，密封面的密封功能长时间保持。 流体循环槽10包括流体从高压流体侧进入的入口侧部分11和流体流出到高压流体侧的出口侧部分12，流体循环槽10设置在一对密封面S中的一个 相互滑动的滑动部件。 流体循环槽10通过陆部R与低压流体侧隔离。流体循环槽10的出口侧部12的槽宽度朝向出口端逐渐扩大。
