    Abstract: An annular seal is provided for use in a turbomachine. The annular seal may form a generally rectangular cross-section and may include an outer radial surface forming an outer sealing surface and defining at least one annular groove and a plurality of slots spaced circumferentially about the outer radial surface. Each slot may have an end terminating in the at least one annular groove. The annular seal may also include a first axial sidewall forming a sidewall sealing surface and a recessed portion and a second axial sidewall opposing the first axial sidewall. At least one annular groove and the plurality of slots may be configured to maintain a low pressure environment across at least a portion of the outer radial surface. The second axial sidewall, the recessed portion, and the inner radial surface may be configured to maintain a high pressure environment there across during operation of the turbomachine.

  • Publication number: 20150008651
    Abstract: A sealing arrangement includes a first member having a non-circular hole, a second member having a non-circular and annular groove that extends continuously around an outer circumference of the second member, and a seal made of an elastic material and seated in the groove. An outer circumference of a body of the seal is in contact with a wall of the first member defining the non-circular hole, and an inner circumference of the body of the seal is in contact with a wall of the second member defining the groove. At least one protrusion protrudes from at least one portion of the body where a relatively low contact pressure is applied between the body and the groove and along a direction of insertion of the second member into the first member.

  • Patent number: 8820754
    Abstract: A seal assembly for an axial flow gas turbine engine includes a rotatable component having a radially extending mate face, a seal slot formed in the mate face, and a seal member slidably disposed in the seal slot. The seal slot includes a radially outer wall and an opposing radially inner wall extending into the component in a circumferential direction from the mate face. The radially outer wall is angled radially inwardly from the mate face toward an inner end portion of the seal slot. Rotation of the seal assembly during operation of the engine produces a centrifugal force on the seal member to effect movement of the seal member in the circumferential direction out of the seal slot.
