Abstract (en)
[origin: WO2020256678A2] The present invention relates to a brush seal (1) which provides sealing between the high pressure regions and the low pressure regions around the shafts which rotate at high speed and particularly provided in turbo machines like airplane motors, vapor turbines and gas turbines, and which increases performance and which is compliant to different diameters thanks to the flexible structure thereof in circular direction and which comprises fibers (2) which provide sealing by forming a surface which prevents flow. The subject matter brush seal (1) is characterized by comprising at least two plates (4) which have notched structure and between which the bunches, formed by fibers (2), are fixed in the form of sandwich; notches (5) provided on the notched plates (4) and which provide freedom to the notched plates (4) in the direction of circular bending; extension regions (6) which have plate (4) parts which remain between the notches (5).
