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.
