Patent ID: 11125335

Abstract:
In an exemplary embodiment, a sliding component includes a pair of sliding parts sliding relatively to each other. One sliding part is a stationary-side seal ring 7, and the other sliding part is a rotating-side seal ring 4, wherein the seal rings have sliding faces S formed radially for sealing a liquid or a misty fluid as a sealed fluid against leakage. At least one of the sliding faces S is provided with: spiral grooves 11 which have upstream ends 11a connected to a leakage side, and downstream ends 11b not connected to a circumferential edge on a sealed-fluid side, and are disposed at an angle from upstream to downstream; and discharge grooves 10 disposed at an angle such that their upstream ends 10a are located on the leakage side and their downstream ends 10b are located on the sealed-fluid side.
