WIPO Patent Application WO/2024/004657
Kind Code:
A1
Abstract:
Provided is a sliding component capable of preventing poor lubrication between sliding surfaces during low-speed relative rotation. In this sliding component in which a pair of sliding rings 10, 20 rotate relative to each other and partition a first fluid space S1 and a second fluid space S2, a sliding surface of corresponding one of the pair of sliding rings 10, 20 has: a specific dynamic pressure generation groove 16 that is provided on the first fluid space S1 side and that generates dynamic pressure by means of a first fluid F; a dynamic pressure generation groove 15 that is provided closer to the second fluid space S2 side as compared to the specific dynamic pressure generation groove 16 and that generates dynamic pressure by means of a second fluid A; a communication groove 131 in communication with the first fluid space S1; a circumferential-direction groove 132 provided closer to the second fluid space S1 side as compared to the specific dynamic pressure generation groove 16 and extending in the circumferential direction from the communication groove 131; and a first fluid introduction groove 14 which is provided closer to the second fluid space S2 side as compared to the circumferential-direction groove 132 and through which the first fluid F is introduced.
