  • Patent number: 9951786
    Abstract: A centrifugal pump impellor includes balancing holes that reduce axial thrust while minimizing the loss of pump efficiency. In one general aspect, the balancing holes penetrate the rear shroud between the blades, and are angled in both axial and rotational directions so as to direct the leakage fluid approximately parallel to the primary process fluid, so that it causes minimal interference with the primary fluid flow. In a second general aspect, the balancing holes extend from the rear cavity within the impellor blades and through the leading edges of the blades, thereby entering the primary flow in locations where the process fluid is almost static relative to the blades. This minimizes the impact on the flow of the process fluid past the blades, and thereby minimizes the loss of pump efficiency caused by the balance holes. In embodiments, each blade leading edge includes a plurality of balancing hole outlets.

  • Patent number: 9683455
    Abstract: A component for releasing a flow of material into an environment subject to periodic fluctuations in pressure, which has: a first surface that includes an inlet; a second surface that includes an outlet; a duct formed in the component and extending from the inlet to the outlet so, when the component is in use, a flow of material received at the inlet can flow along the duct to be released at the outlet into an environment subject to periodic fluctuations in pressure. The duct includes a constriction at which it decreases in cross-sectional area as it progresses from the inlet to the outlet. This can help reduce the variation in flow rate of material released at the outlet caused by the periodic fluctuations in pressure, and may help to avoid/reduce ingestion, when the component is in use. Preferably, the component is configured to form part of a gas turbine engine.

    Abstract: A system for sealing an oil chamber from an adjoining exterior volume, and a turbo-machine including a sealing system. The system for sealing the oil chamber from the adjoining exterior volume, both of which are delimited by a mobile rotor in rotation about an axis and a part, fixed or mobile, includes: a first seal arranged between the rotor and the part; a second seal that is mounted between the rotor and the part and which is offset longitudinally relative to the first seal, to form with the first seal a sealing chamber delimited by the rotor, the part, and the two seals; and a mechanism for supplying gas to the sealing chamber, such that the gas can be compressed when the rotor begins to rotate, the chamber communicating with the oil chamber and/or the adjoining exterior volume via the first and second seals alone, respectively.

  • Publication number: 20140291991
    Abstract: A wind speed amplification device that cooperates with a wind turbine to amplify ambient wind speed conditions directed to the blades of the wind turbine. In one embodiment, the amplification device has a conical shape that is configured to generally overly the central hub associated with an axis of rotation of the blades. In another embodiment, the amplification device has a wedge shape that is positioned radially outboard of the operating footprint of the blades and extends upstream of the plane of operation of the turbine blades. In a preferred embodiment, the wedge shaped amplification device includes a forward wedge portion and a rearward wedge portion that extend in opposite directions relative to the plane of operation of the blades.

  • Patent number: 8827663
    Abstract: A rotary pump including an impeller rotatable within a housing. A load is imposed on the impeller as it rotates, in a direction that is substantially parallel to the axis of rotation and wherein the load stabilises the motion of the impeller. The load may be achieved by magnetically biasing the impeller.

  • Patent number: 8807921
    Abstract: A bearing foil assembly includes a top foil, an intermediate foil, and a bump foil. The bump foil is provided with corrugations at circumferentially spaced locations. The bump foil has an end that is bent radially outwardly from a center of the foil assembly. The top foil has a bent portion extending radially outwardly and adjacent to the bent end of the bump foil. A first radius of curvature is defined to a curved portion leading into the bent portion at a first end adjacent to the bent end. A second radius of curvature is defined at an end of the bent portion on an end opposed to the bent end. A ratio of the first radius of curvature to the second radius of curvature is between 0.6 and 10. A bearing assembly, a shaft sub-assembly, an air machine, and a method of assembling a bearing into an air machine are also disclosed.

  • Patent number: 8740549
    Abstract: A lubrication system for turbocharger(s) ensures continuous lubrication of bearings and shaft of the turbocharger with lubricant retention during start and shut down of turbocharger-associated systems thereby enhancing the performance and turbocharger life. A shaft and bearings are lubricated by introducing pressurized lubricating oil through an oil inlet passage in the bearing housing and after lubricating, the lubricant returns to the engine oil sump located below the turbocharger through the oil outlet passage. A valve in the oil inlet pipe line permits lubricant flow to the bearings during engine running, and when the engine stops and oil pressure falls below the valve opening pressure, the valve shuts and traps the lubricant in oil inlet pipe that is above the valve. The oil outlet pipe retains sufficient lubricant in the bearing housing which lubricates the shaft and bearings post engine shutdown.

  • Patent number: 8727695
    Abstract: An apparatus and method is disclosed herein in which a heat-transfer fluid can be directed through a gap defined between a fillet and a chamfer. The apparatus includes a first member having a body portion and a flange portion projecting from the body portion. The flange portion extends along an endless path encircling an axis to define a receiving aperture. A fillet is defined at a junction of the body portion and an inner surface of the flange portion. The apparatus also includes a second member having a plug portion receivable in the receiving aperture. The plug portion includes a first surface operable to abut the body portion and limit movement of the plug portion into the receiving aperture. The plug portion also includes a second surface slidably engageable with the inner surface of the flange portion to guide movement of the plug portion into the receiving aperture along the axis.

  • Publication number: 20140119883
    Abstract: A liner wall insert is provided for a compressor rotor stage of a gas turbine engine. Several liner wall inserts are provided radially outboard of the tips of the rotor blades. The liner wall inserts have bleed flow channels formed therein. The bleed flow channels are arranged to remove flow from a trailing edge region of the stage and re-inject the bleed flow at an upstream region. The re-injected bleed flow alters the flow field around the tips of the rotor blades, for example the tip leakage flow. Thus, the bleed flow is used to improve the efficiency of the compressor rotor stage, and thus of the gas turbine engine.
