Patent abstract
An intershaft seal is provided for inner and outer coaxial shafts which rotate relative to each other. The seal is located in an annular space between the shafts and maintains an axial pressure differential between a fluid pressure on the first side of the seal and a different fluid pressure on the other, second side of the seal. The seal includes a first runner which extends circumferentially around a first one of the shafts and projects therefrom into the annular space. The seal further includes a sealing ring which is coaxial with the shafts.
