Abstract:
A rotary machine having a component rotatable about an axis, comprising:a stationary component having an annular groove about the axis, at least one axially directed locating flange about the axis and in part defining a slot opening into the groove, and a stop;a segment body for forming one of a plurality of arcuate segments about the axis of the machine and for partial disposition in the groove of said stationary component;said segment body having an arcuate seal face, at least one axially directed flange for disposition in the groove and a neck portion receivable in said slot and interconnecting said flange and said seal face, said segments being movable in said groove between radially inner and outer positions relative to said stationary component;an elongated retention clip disposed between said segment body and said stationary component, said clip having a generally radially outwardly extending projection adjacent one end thereof engaging said stop carried by the stationary component and a generally radially inwardly extending projection adjacent an opposite end thereof engaging said segment for supporting said segment body preventing circumferential downward displacement of the segment body about the groove under gravity forces; andsaid segment body including an arcuate outward face in said groove and in opposition to an arcuate radial inward face of said stationary component in said groove, said clip including an arcuately extending body between opposite end projections thereof for extending in said annular groove about said axis, said clip being substantially rigid between said opposite end projections, said clip body extending arcuately and lying radially between said segment body face and said stationary component face.
