    摘要： This shaft sealing device and rotary machine equipped therewith are provided with: a sealing body (12) configured by stacking, in the circumferential direction of a rotating shaft (6), a plurality of thin sealing pieces (20) extending from a housing (9) towards the inside of the rotation shaft (6) in the radial direction; and a low-pressure-side side sealing plate (17) which is arranged along the low-pressure side of the sealing body (12) and in which a plate surface (17d) facing the low-pressure side is pressed against the inner wall surface (9e) of the housing (9) by means of the fluid pressure applied from the high-pressure side to the low-pressure side, the aforementioned inner wall surface (9e) facing the axis line direction. A protrusion (9f) for blocking the downward flow (9) towards the inside of the low-pressure-side side sealing plate (17) in the radial direction along the low-pressure side of the sealing body (12) is formed on the inside of the low-pressure-side side sealing plate (17) in the radial direction, and a communication path (9g) for guiding, to a low-pressure-side region, the downward flow (d) blocked by means of the protrusion (9f) is formed on the housing (9).

    摘要： Disclosed is a shaft sealing device (100) including: a housing (60) in which an annular recessed portion (61) is formed and which is fixed to a stator; a sealing body (20), a radially outer portion of which is accommodated by the annular recessed portion (61); and a high pressure-side sealing plate (40) that is disposed along the sealing body (20) in a high pressure region (Hs). An inflow groove (66) is formed in any member of the housing (60), the high pressure-side sealing plate (40), and the sealing body (20) such that a fluid flows through the sealing body (20) from a low pressure region (Ls) during a non-normal operation in which pressure in the high pressure region (Ls) is higher than pressure in the high pressure region (Hs). A communication path (69) is formed in the housing (60) such that the inflow groove (66) and a space in the high pressure region (Hs) communicate with each other via the communication path (69).

    摘要： A shaft seal device that seals between the outer peripheral surface of a rotating shaft and a stationary member that is provided on the outer peripheral side of the rotating shaft, provided with a thin-plate seal that has a plurality of thin plates that are arranged in the circumferential direction of the rotating shaft and an abradable seal that is arranged at a position differing with the thin-plate seal in the axial direction, and having a free-cutting material that is disposed at either one of the rotating shaft and the stationary member, and a seal fin that projects toward the rotating shaft or stationary member from the other of the rotating shaft and the stationary member.
