A seal assembly for effecting a seal between a stationary housing and a rotatable cylinder includes a plurality of arcuate segments radially disposed about the outer circumference of the cylinder. Each segment has an axial sealing surface defining a radius approximately equal to that of the rotatable cylinder and additionally has an end section for overlapping adjacent segments thus creating a gap and radial interface between the adjacent circumferentially disposed segments. The sealing assembly additionally comprises means for sealing the gaps formed by the adjacent overlapping segments, apparatus for tensioning the segments radially about the outside circumference of the cylinder and studs for removably attaching each segment to the housing while concurrently permitting radial displacement of each segment independently from its adjacent segments. |
