    摘要： The embodiments described herein provide a cloth seal for use with turbine components. The cloth seal includes first and second cloth layers. One or more central shims are positioned between the first and second cloth layers so as to block a leakage flow path. Another shim is positioned on and seals the opposite side of the first cloth layer from the one or more central shims positioned between the first and second cloth layers so as to block another leakage flow path. Yet another sealing shim may be positioned on the opposite side of the second cloth layer from the one or more central shims positioned between the first and second cloth layers to as to seal the opposite side of the second cloth layer and block another leakage flow path.

    摘要： A seal assembly for a rotary machine is provided. The seal assembly includes multiple sealing device segments disposed intermediate to a stationary housing and a rotor. Each of the segments includes at least one plate and a sealing element. The seal assembly also includes multiple inter-segment gaps formed between the multiple sealing device segments. Further, for each pair of adjacent sealing device segments, at least one pair of adjacent plates includes one plate overlapping another plate at an inter-segment gap.

    摘要： The present application thus provides a retractable seal system for use between a high pressure side and a low pressure side of a turbine engine. The retractable seal system may include a seal positioned in a slot of a stationary component, a pressure balance pocket positioned about the seal, and a conduit in communication with the pressure balance pocket and the high pressure side.
