Title:
SLIDING COMPONENT
Document Type and Number:
WIPO Patent Application WO/2018/139231
Kind Code:
A1
Abstract:
Provided is a sliding component with which it is possible to improve lubrication by actively introducing a fluid to a sliding surface when from startup to normal operating state, prevent the deposition of wear particles and contaminants within sliding surfaces, and prevent the occurrence of wear of and leakage from sliding surfaces. The sliding component comprises a pair of sliding components 4, 7 which slide relative to one another. One of the sliding components is a fixed-side sealing ring 7, and the other sliding component is a rotating-side sealing ring 4. These sealing rings 4, 7 have a sliding surface S formed in the radial direction, and seal against leakages of liquid or mist-form fluids which are the fluids being sealed, and comprise, on at least one of the sliding surfaces S: a positive pressure-generating mechanism 11 having a positive pressure-generating groove 12 which is connected with the sealed fluid-side edge of the sliding surface S, and which is not connected to the leakage-side edge; and a discharge groove 10 which is provided in an inclined manner such that the upstream-side end is positioned on the leakage side and the downstream-side end is positioned on the sealed fluid side.
