| 主权项 | 1. A brush seal for a turbine having a rotating axis, the brush seal comprising: an annular layer of filaments being L-shaped in cross section and including an axial portion of the filaments extending in a direction substantially parallel to the rotating axis and a radial portion extending in a direction substantially perpendicular to the rotating axis, wherein a first end of the filaments is at an end of the radial portion and faces a rotating component of the turbine and a second end region of the filaments includes an end of the axial portion of the filaments and is configured to be fastened to a stationary component of the turbine, and annular side rails which sandwiched the second end region of the filaments, wherein the side rails are coaxial and aligned along a common radius, and one of the annular side rails seats in a step or groove in a stationary annular structure which supports the filaments. | ||
