Abstract: An aspirating face seal for use with a rotary machine includes a rotating seal ring including a radially outer surface that includes an oblique portion. A stationary seal ring is coupled proximate the rotating seal ring such that a first gap is defined therebetween. The stationary seal ring is movable along a centerline axis of the rotary machine between an open position and a sealed position, and includes an extension member that extends across the first gap. An auxiliary seal includes at least one seal tooth that includes a seal tooth tip. The at least one seal tooth extends radially inward from the extension member such that a second gap is defined between the seal tooth tip and the oblique portion.

Abstract: A seal for a rotary machine includes a flexible element extending circumferentially about a rotor and extending generally radially from a first end to a free second end. The flexible element is coupled proximate the first end for rotation with the rotor. The flexible element extends at substantially a first angle between at least an intermediate portion of the flexible element and the free second end when the rotor is operating at less than a critical speed, such that a clearance gap is defined between the free second end and a stationary portion. The seal also includes a retaining plate having a stop that orients the flexible element at a second angle proximate the free second end when the rotor is operating at equal to or greater than the critical speed, such that the flexible element forms a dynamic seal between the rotor and the stationary portion.
