Slide component
The purpose of the present invention is to provide a slide component that can exhibit sealing performance and lubricity regardless of rotating direction. A pair of slide components 4, 7 that slide relative to each other have sliding faces S that slide relative to each other, and a sealed fluid-side periphery 16 and a leakage-side periphery 15 . The sliding face S of at least one slide component 4 of the pair of slide components 4, 7 includes: a fluid introduction groove 13 in communication with the sealed fluid-side periphery 16 ; a first pressure generation mechanism 12 of which one end is in communication with the fluid introduction groove 13 and the other end is surrounded by a land portion R 1 ; and a second pressure generation mechanism 11 of which one end is in communication with the leakage-side periphery 15 and the other end is surrounded by an annular land portion R 2 . The fluid introduction groove 13 and the other end 12 e of the first pressure generation mechanism 12 include overlapping portions Lp overlapping circumferentially.
1. A pair of slide components that slide relative to each other, wherein:
the pair of slide components have sliding faces that slide relative to each other, a sealed fluid-side periphery, and a leakage-side periphery,
the sliding face of at least one slide component of the pair of slide components includes: a fluid introduction groove in communication with the sealed fluid-side periphery;
a first pressure generation mechanism of which one end is in communication with the fluid introduction groove and an other end is surrounded by a land portion; and
a second pressure generation mechanism of which one end is in communication with the leakage-side periphery and an other end is surrounded by an annular land portion, and
the fluid introduction groove and the other end of the first pressure generation mechanism include overlapping portions overlapping circumferentially, wherein
the fluid introduction groove has an inclined wall part facing the other end of the first pressure generation mechanism; and
the inclined wall part is inclined to a direction to approach the one end of the first pressure generation mechanism with respect to a radial axis connecting an intersection point of the inclined wall part and the sealed fluid-side periphery and a center of one of the slide components.
2. The slide component according to claim 1 , wherein the fluid introduction groove and the first pressure generation mechanism are arranged nearer the sealed fluid-side periphery than the annular land portion.
3. The slide component according to claim 1 , wherein the fluid introduction groove is formed into a trapezoidal shape.
4. The slide component according to claim 1 , wherein the fluid introduction groove is formed into a triangular shape.
5. The slide component according to claim 1 , wherein the first pressure generation mechanism consists of a groove part.
6. The slide component according to claim 1 , wherein the first pressure generation mechanism consists of a dimple group consisting of a plurality of dimples.
7. The slide component according to claim 1 , wherein the second pressure generation mechanism consists of a groove part.
8. The slide component according to claim 1 , wherein the second pressure generation mechanism consists of a dimple group consisting of a plurality of dimples.
9. The slide component according to claim 1 , wherein the second pressure generation mechanism is formed into a spiral shape.
10. The slide component according to claim 1 , wherein the depth of the fluid introduction groove is deeper than the depth of the first pressure generation mechanism.
11. The slide component according to claim 1 , wherein the depth of the fluid introduction groove is same as the depth of the first pressure generation mechanism.
