  • Tilt pad bearing with through-pivot lubrication
    Patent number: 9739310
    Abstract: A tilt pad bearing may include a support structure having first and second support structure surfaces. A pivot may have first and second pivot surfaces, and the first pivot surface may be coupled to the second support structure surface. A pad may have first and second pad surfaces, and the first pad surface may be coupled to the second pivot surface. A path of fluid communication may extend from the first support structure surface, through the pivot, and to an opening in the second pad surface.
    Type: Grant

  • Seal assembly, cartridge, and method
    Patent number: 7201379
    Abstract: A seal assembly and cartridge for sealing a space between a rotating member and a stationary member in which a sleeve extends around the rotating member and with the inner surface of the sleeve being spaced from the outer surface of the rotating member to form a gap. Pressurized fluid is introduced to the sleeve to establish and maintain a predetermined gap between the sleeve and the rotating member, so that the pressure of the fluid can be varied to maintain the predetermined gap despite variations of the diameter of the rotating member during its rotation.
