SLIDING COMPONENT
First Claim
1. A sliding component characterized in that:
- with respect to a pair of sliding parts that slide relative to each other, one sealing face has a fluid circulation groove comprising an inlet through which fluid enters from a high-pressure fluid side, an outlet through which fluid is released to the high-pressure fluid side, and a communicating part through which the inlet and outlet communicate with each other;
wherein the fluid circulation groove is isolated from a low-pressure fluid side by a land, a positive-pressure generation mechanism is provided in an area surrounded by the fluid circulation groove and high-pressure fluid side, and the positive-pressure generation mechanism communicates with the inlet and is isolated from the outlet and high-pressure fluid side by a land.

Abstract
A sliding component is characterized in that: with respect to a pair of sliding parts that slide relative to each other, one sealing face has a fluid circulation groove including an inlet through which fluid enters from the high-pressure fluid side, an outlet through which fluid is released to the high-pressure fluid side, and a communicating part through which the inlet and outlet communicate with each other; wherein the fluid circulation groove is isolated from the low-pressure fluid side by a land, a positive-pressure generation mechanism is provided in the area surrounded by the fluid circulation groove and high-pressure fluid side, and the positive-pressure generation mechanism communicates with the inlet and is isolated from the outlet and high-pressure fluid side by a land.

10. A sliding component characterized in that:
- with respect to a pair of sliding parts that slide relative to each other, one sealing face has a fluid circulation groove comprising an inlet through which fluid enters from a high-pressure fluid side, an outlet through which fluid is released to the high-pressure fluid side, and a communicating part through which the inlet and outlet communicate with each other;
wherein the fluid circulation groove is isolated from a low-pressure fluid side by a land, a positive-pressure generation mechanism is provided in an area surrounded by the fluid circulation groove and high-pressure fluid side, the positive-pressure generation mechanism communicates with the inlet, a spiral groove that discharges fluid to the high-pressure fluid side by means of relative sliding of the sliding parts is provided on an outside of an area surrounded by the fluid circulation groove and high-pressure fluid side and between the positive-pressure generation mechanism and the outlet and high-pressure fluid side, the spiral groove is isolated from the low-pressure fluid side by a land, and a surface on which the spiral groove is provided is set lower than the land and higher than the positive-pressure generation mechanism.
- with respect to a pair of sliding parts that slide relative to each other, one sealing face has a fluid circulation groove comprising an inlet through which fluid enters from a high-pressure fluid side, an outlet through which fluid is released to the high-pressure fluid side, and a communicating part through which the inlet and outlet communicate with each other;
