| 20090206554 | STEAM TURBINE ENGINE AND METHOD OF ASSEMBLING SAME - A method is provided for assembling a turbine engine. The method includes providing a retro-fit seal ring assembly that includes a plurality of unitary, arcuate ring segments that are circumferentially-spaced about a center axis of the ring assembly. Each of the plurality of ring segments includes a body and at least one integrally formed tooth that extends radially inward therefrom. The methods also includes extending at least one fastener through the body of each of the plurality of ring segments, and removably coupling each of the plurality of ring segments to an outer surface of a stationary component within the turbine engine using the at least one fastener. | 08-20-2009 |
| 20100164181 | Sealing Ring for Turbo Engines - A sealing ring for turbo engines is provided. The sealing ring includes individual sealing segments, between which springs are mounted. Locking elements are provided on the parting joint of the turbo engine to retain the sealing segments. In order to ensure that the sealing elements can be securely closed on the parting joint, the sealing segments are positively interconnected on the parting joint. | 07-01-2010 |
| 20110127728 | SEALING RINGS FOR A LABYRINTH SEAL - In sealing rings for a labyrinth seal that are arranged on a rotationally symmetrical component and in frictional contact with a stationary run-in layer, a part of the sealing ring ( | 06-02-2011 |
| 20120133101 | METHOD AND APPARATUS FOR PACKING RINGS - A seal assembly for a turbomachine is provided. The turbomachine includes a stationary housing and a rotor rotatable about an axis. The seal assembly includes a plurality of arcuate packing ring segments disposed intermediate to the rotor and the stationary housing, and a plurality of inter-segment gaps disposed between the plurality of arcuate packing ring segments. The plurality of inter-segment gaps are inclined at a first angle from a radial axis of the rotor and inclined in a direction of motion of the plurality of arcuate packing ring segments. The seal assembly also includes a biasing member disposed intermediate to the stationary housing and the plurality of arcuate packing ring segments and coupled to both. | 05-31-2012 |
| 20160097458 | SEALING SEGMENT - The invention relates to a sealing segment for sealing between a stationary component and a rotating component. The sealing segment having a passage that extends so as to enable pressure balancing between radial ends of the sealing segment so by providing a seal that can ensure a minimum seal distance is maintained without the need for the complexities of actuators or other mechanical devices. | 04-07-2016 |
