Abstract
Even when a fluid discharge for discharging high-pressure fluid (sealed fluid) to a high-pressure side of a sealing face is provided, the disclosed sliding component prevents precipitation, adhesion and accumulation of a deposition-causing substance through a dehydration condensation reaction between the high-pressure fluid and low-pressure fluid on the sealing face, and also prevents occurrence of cavitation which would otherwise take place in association with a sudden pressure drop due to a discharge of fluid. Disclosed is a pair of sliding components provided, on a high-pressure side of one of relatively sliding sealing faces thereof, with a fluid discharge for discharging fluid to a high-pressure fluid side, wherein a buffer groove for reducing penetration of low-pressure fluid toward the high-pressure fluid side is provided in the sealing face S on a low-pressure side of the fluid discharge.
