An axial seal assembly is provided at the interface between adjacent wheels (18) and spacers (32) of a gas turbine rotor and disposed about tubes (58) passing through openings in the rotor adjacent the rotor rim and carrying a thermal medium. Each seal assembly includes a support bushing (80) for supporting a land (70) of the thermal medium carrying tube (58), an axially registering seat bushing (82) disposed in the opposed opening and a frustoconical seal (84) between the seal bushing and seat. The support bushing (80) includes a radial flange (88) having an annular recess (90) for retaining the outer diameter edge (93) of the seal, while the seat bushing (82) has an axially facing annular surface (96) forming a seat for engagement by the inner diameter edge (98) of the seal. <IMAGE> |
