  • Retractable compliant plate seals
    Patent number: 7909335
    Abstract: A seal arrangement for sealing the space between a rotating element and a stationary element, the sealing arrangement comprising a compliant plate seal housing supported adjustably in the stationary element, the compliant plate seal housing supporting a compliant plate seal; and a spring system provided between the compliant plate seal housing and the stationary element to bias the compliant plate seal housing in a direction away from a surface of the rotating element. Alternatively, or additionally, one or more actuators may be provided to move the compliant plate seal housing in a direction away from a surface of the rotating element.
    Type: Grant

  • Shaft seal formed of tapered compliant plate members
    Publication number: 20080107525
    Abstract: A shaft seal reduces leakage between a rotating shaft and a stator. The shaft seal includes a plurality of plate members attached to the stator in facing relation. The plate members define a sealing ring between the stator shell and the rotating shaft. A thickness of the plate members tapers from thick to thin from a stator end to a rotating shaft end. In this manner, with the more tightly packed tips of the plate members, axial leakage is reduced by tapering the plate members so that the plate roots are thicker than the plate tips.
