摘要： A low leakage seal for separating two environments and contacting a component surface is provided. The seal includes a base and an annular rib. The annular rib is coupled to and extends from the base. The annular rib includes at least one contact surface configured to contact the component surface having a plurality of angularly cut radial grooves formed therein. The annular rib flexes and pressure energizes in the presence of a pressure differential between the two environments.

摘要： A fluid-cooled seal rotor is described for a seal assembly that includes a seal case, a seal stator, and wherein the rotor has a sealing face on a first side and a heat-transfer structure on a second side. The heat-transfer structure may be a roughened surface. The heat-transfer structure may have protrusions which may be fins, including fins with roughened surfaces. The heat-transfer structure may have additional heat-transfer structures thereon to create complex, including fractal, structures. The fins may be shaped as impellers to move oil over the heat-transfer structure. Channels between fins may have a width greater than twice the boundary layer thickness for the fluid engaged by the fins. The fluid-cooled rotor, the seal assembly having the fluid-cooled rotor, an air turbine starter having the seal assembly, air turbine starters and other machines with rotating shafts using the seal are within the scope of the invention.

摘要： An improved oil seal is provided for sealing passage of rotatable shaft through an end wall of a bearing housing in a turbomachine or the like, wherein the shaft is rotatably supported within the bearing housing by oil-lubricated bearings. The improved oil seal comprises a slinger rotor mounted on the shaft for rotation therewith. The slinger rotor includes a radially outwardly extending slinger ring with radially open slinger ports formed therein, in combination with an axially projecting centrifuge sleeve defining an internal tapered centrifuge surface disposed in close running clearance with an axially projecting cylindrical wall segment on the end wall. During shaft rotation, the centrifuge surface pumps oil in a direction away from the end wall to the slinger ring for discharge through the slinger ports to the interior of the bearing housing. In addition, in the preferred form, the slinger rotor has an internal bore with axially extending lands for press-fit mounting onto the rotating shaft, wherein the lands are separated by ramped slots defining additional tapered centrifuge surfaces for pumping oil away from the end wall of the bearing housing.

摘要： An actuator that at least inhibits the deleterious effects of corrosive fluids, such as seawater, does not rely on relatively expensive materials, and is capable of operation and relatively high pressures includes two sealed buffer chambers. One buffer chamber is supplied with a buffer fluid, and the other buffer chamber is maintained at a vacuum pressure. The buffer fluid in the first buffer chamber helps remove any residual corrosive fluid that may remain on the actuator translation member as it moves into the actuator housing, and any fluid that leaks into the second chamber will boil as a result of the vacuum pressure therein.
