초록

A brush seal arrangement for sealing cooperation between a shaft and a surrounding member which is relatively rotatable with respect to the shaft. The brush seal includes an annular rotor disposed in surrounding relationship to the shaft and sealed with respect to the housing, and the rotor mounts thereon first and second annular bush members which are disposed in axially spaced relation and which have annular edge portions which create a frictional and sealing engagement with the shaft to nonrotatably and sealingly couple the rotor to the shaft. A passa...
