Abstract
A turbomachine comprises a nozzle segment including an inner shroud defining a bottom surface and a nozzle flange defining a forward side surface and an aft side surface. A floating rotor seal is coupled to the nozzle flange via a carrier flange. The carrier flange includes a forward wall and an aft wall. The nozzle flange is positioned between the forward and aft walls and a flowpath is defined therebetween. A seal pocket is defined in one of the forward wall or the aft wall and is in fluid communication with the flowpath. At least one linear seal segment is partially disposed within the seal pocket. The linear seal segment is configured to form a seal against the nozzle flange or the bottom surface in response to pressurization of the seal pocket via a working fluid in the flowpath.
