SLIDING COMPONENT
A sliding component is characterized in that dimples are provided on one sealing face of a pair of sliding parts that mutually slide relative to each other, and grooves with directionality are provided in a cavitation formation area in each dimple.
1 . A sliding component characterized in that dimples are provided on one sealing face of a pair of sliding parts that mutually slide relative to each other, and grooves with directionality are provided in a cavitation formation area in each dimple.
2 . A sliding component according to claim 1 , characterized in that the grooves with directionality are provided at least on a low-pressure fluid side of the cavitation formation area.
3 . A sliding component according to claim 1 , characterized in that continuous grooves that communicate with a high-pressure fluid side are provided at least in a location other than the cavitation formation area in the dimple.
4 . A sliding component according to claim 1 , characterized in that the grooves with directionality provided in the cavitation formation area in the dimple are formed such that their directions become symmetrical relative to a sliding direction of the sealing face with reference to a center of a sliding direction of the dimple.
5 . A sliding component according to claim 2 , characterized in that continuous grooves that communicate with a high-pressure fluid side are provided at least in a location other than the cavitation formation area in the dimple.
6 . A sliding component according to claim 2 , characterized in that the grooves with directionality provided in the cavitation formation area in the dimple are formed such that their directions become symmetrical relative to a sliding direction of the sealing face with reference to a center of a sliding direction of the dimple.
