Abstract
In an exemplary embodiment, a sliding component includes a pair of sliding partsandsliding relative to each other, with a high-pressure gas present on one side of the pair of sliding partsandand a low-pressure liquid on the other side. At least the sliding parthas a sliding face S provided with positive pressure generation mechanismseach having a positive pressure generation groove, and provided with an annular deep grooveon the high-pressure gas side. The annular deep grooveis isolated from the high-pressure gas side by a land R, and is connected to the low-pressure liquid side through radial deep grooves. The sliding component is capable of fulfilling both conflicting conditions of sealing and lubrication, with a gas on the high-pressure fluid side and a liquid on the low-pressure fluid side.
