摘要： A sliding component is characterized in that, on one sealing face of a pair of sliding parts that slide relative to each other, multiple positive pressure-generating mechanisms that include extremely shallow parallel grooves running roughly in parallel with the sealing face and having submicron-level height differences are provided independently in the circumferential direction, and that extremely shallow thin grooves are formed on the sealing face on the low-pressure fluid side of the extremely shallow parallel grooves, wherein the extremely shallow parallel grooves communicate with the high-pressure fluid side, and the extremely shallow thin grooves communicate with the extremely shallow parallel grooves, but are isolated from the low-pressure fluid side by a seal area, thereby reducing a leakage rate of sealed fluid and significantly improving lubrication characteristics at startup or stop at the same time.

摘要： Provided is a sliding component with less fluid leakage. A sliding component has a pair of sliding members at least one of which has positive pressure generation mechanisms and negative pressure generation mechanisms formed at a sliding surface of the sliding member. The negative pressure generation mechanisms are arranged on a low-pressure fluid side with respect to the positive pressure generation mechanisms. Adjoining two of the negative pressure generation mechanisms in a circumferential direction overlap with each other in a radial direction.

摘要： A sliding component includes a pair of sliding parts of which a rotating-side sliding part rotates in both forward and reverse directions. In the sliding component, at least one of the sliding parts has a sliding face provided with positive pressure generation grooves on the sealed fluid side, and a negative pressure generation groove on the opposite-to-sealed-fluid side and separated from the opposite-to-sealed-fluid side by a land, and a deep groove communicating with the sealed fluid side on the sealed fluid side of the negative pressure generation groove. The positive pressure generation grooves each have an upstream end communicating with the deep groove, and the negative pressure generation groove has an upstream inlet and a downstream outlet that communicate with the deep groove, and an intermediate portion between the inlet and the outlet located on the opposite-to-sealed-fluid side of the inlet and the outlet.

摘要： In an embodiment, in a slide component, dynamic pressure generation grooves 10 are provided on a sealing face of at least one of a pair of slide parts 4, 7 so as to be isolated with no communication from the sealed fluid side and the leakage side by land portions R of both the sealing faces, and a plurality of independently-formed minute recessed sections 11 is provided at positions on the sealing face IS between the dynamic pressure generation grooves 10 and the leakage side, the positions being separated in the radial direction from the dynamic pressure generation grooves. The slide component can make the sealing faces fluid-lubricant and low frictional and prevent leakage of a sealed fluid and incoming of dust to the sealing faces at the time of normal operation.

摘要： In an embodiment, a slide component includes one slide part 5 provided, on a low-pressure side of a sealing face thereof, with a negative pressure generation mechanism 10 including a negative pressure generation groove 10. The negative pressure generation groove 10a communicates with a high-pressure fluid side and is separated from a low-pressure fluid side by a land portion R. Another slide part 1 is provided, in a sealing face thereof, with at least one interference groove 15 communicating with the high-pressure fluid side for producing pressure variations in a fluid in the negative pressure generation groove 10a. The at least one interference groove 15 has an end 15a on an inside-diameter side extending to a position to radially overlap the negative pressure generation groove 10a.
