    摘要: {Technical Problem} Provide a sliding component that reduces the leakage rate of sealed fluid and significantly improves the lubrication characteristics at startup or stop, while being actuated by means of fluid lubrication in the rotation phase, thereby achieving the effects of sealing and lubrication at the same time. {Solution to Problem} The 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 comprise 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; extremely shallow thin grooves are formed on the sealing face on the low-pressure fluid side of the extremely shallow parallel grooves; 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.

    摘要: {Technical Problem} Provided is a shaft seal device whereby both sustained sealing function and low friction in the seal section can be realized. {Solution to Problem} In a lip-type seal shaft seal device equipped with a lip seal for sealing a rotary member and a stationary member concentrically disposed to the inside and outside in a radial direction, a plurality of aeration-creating parts for creating aeration through relative rotational sliding of the lip seal and the rotary member are formed in separated fashion in the circumferential direction on the outside peripheral surface of the rotary member. The aeration-creating parts are configured from a plurality of fine grooves arranged in the circumferential direction and extending along the axial direction of the rotary member. The lip of the lip seal extends towards the outside atmosphere side, leaving a portion of the aeration-creating parts at the sealed fluid side in the axial direction.

    摘要: {Technical Problem} To provide a mechanical seal which will not leak when stationary; which operates using fluid lubrication and prevents leakage during rotation, including at the start of rotation; and which enables airtightness and lubricity to be exhibited. {Solution to Problem} A plurality of sealed-fluid-accommodating blocks separated in the circumferential direction are formed on either the sealing face of a fixed ring or the sealing face of a rotating ring so as to communicate with a sealed fluid accommodation space. Pumping parts for creating a pumping action due to the fixed ring and the rotating ring sliding while undergoing relative rotation are formed on a bottom part of the plurality of sealed-fluid-accommodating blocks. The pumping parts formed on the bottom parts of the plurality of sealed-fluid-accommodating blocks are provided with an intake pumping part which acts in a direction in which the sealed fluid is drawn in and a discharge pumping part which acts in a direction in which the sealed fluid is discharged.

    摘要: Provided is a slide component that can prevent deposit formation on a sealing face as well as promoting circulation of a fluid on sealing faces while fulfilling both conflicting conditions of sealing and lubrication, to maintain the sealing function of the sealing faces for a long period of time. One slide part 5 is 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. The other 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.
