<p>A seal assembly (10) for effecting a seal between a stationary housing (12) and a rotatable cylinder (16) comprising a plurality of arcuate segments (40) radially disposed about the outer circumference of said cylinder (16). Each segment (40) has an axial sealing surface (100) defining a radius approximately equal to that of the rotatable cylinder (16) and additionally has end sections (102 and 104) for overlapping adjacent segments (40) thus creating a gap (103) and radial interface between said adjacent circumferentially disposed segments. The sealing assembly (10) additionally comprises elastomeric elements (64) for sealing the gaps (103) formed by the adjacent overlapping segments (40), a spring loaded cable (52) for tensioning the segments (40) radially about the outside circumference of the cylinder (16) and threaded studs (44) for removably attaching each segment (40) to the housing (12) while concurrently permitting radial displacement of each segment (40) independently from its adjacent segments.</p> |
