Sliding components

Abstract

A pair of sliding components have a pair of sliding surfaces which rotate relative to each other to partition a sealed fluid space and a leakage space. A sliding surface is provided with a plurality of dynamic pressure generation grooves with different radial lengths. A plurality of dynamic pressure generation grooves are arranged such that a contour of a tip on the leakage space side draws peaks each of which is protruded toward the leakage space and valleys each of which is recessed toward the sealed fluid space and the peaks and valleys are alternately arranged in a circumferential direction, and the sliding surface is further provided with at least one fluid recovery groove which is located on the downstream side of the peak in a relative rotation direction and on the leakage space side.

Dependencies are inferred from the claim text.
