摘要: A pressure balance seal includes a sealing surface facing an inward radial direction, and a stator interface comprising at least one surface interfacing with a stator. The pressure balance seal further includes a friction reducing feature. The friction reducing feature includes a cavity on the sealing surface. The cavity is configured to receive a fluid such that a normal force acting on the pressure balance seal is counterbalanced by a force generated by a pressure of the fluid.

摘要: An aspirating face seal includes a primary seal, a secondary seal, and a biasing device. The primary seal includes a first seal component and a second seal component. The first seal component is configured to be coupled to a rotor and rotatable with the rotor. The secondary seal includes a plurality of flexible elements and configured to be disposed between the second seal component and a stator housing. A biasing device is coupled to the second seal component such that the second seal component is biased along an axial direction away from the first seal component during a non-operating condition.
