  • Patent number: 11331629
    Abstract: A fiber bundle cartridge for a fiber membrane degassing system includes an inner sleeve including one or more perforations and a fiber bundle positioned radially outward from the inner sleeve. The fiber bundle has an annular shape defining a central bundle axis. The perforations of the inner sleeve define a plurality of inlets and/or outlets facing radially with respect to the central bundle axis. A fiber membrane degassing system includes a housing defining a cylindrical volume having at least one inlet and at least one outlet. The system includes at least one fiber within the cylindrical volume, where fluid flowing through the cylindrical volume from the at least one inlet to the at least one outlet flows perpendicular to a longitudinal dimension of the fiber. A method of degassing a liquid includes directing a liquid volume through a fiber bundle in a direction radial to a longitudinally extending bundle axis.

  • Patent number: 9416880
    Abstract: A rotary metering valve assembly includes a stationary body plate having a first contact surface. Also included is a valve plate having a second contact surface disposed in contact with the first contact surface of the stationary body plate, wherein the valve plate is configured to rotate relative to the stationary body plate. At least one of the first contact surface and the second contact surface comprises a surface flatness of less than about 2.4 ?m (about 93 ?in) and a surface roughness of at least about 0.2 ?m (about 8 ?in).

  • Patent number: 9399953
    Abstract: A pump sharing valve for a gas turbine engine fuel system includes a housing having multiple ports. A sleeve is arranged in the housing and includes an inlet window and first, second and third windows axially spaced apart from one another. A spool is slidably received in the sleeve and includes a diameter and first and second cylindrical portions. The first cylindrical portion selectively connects the inlet window to the second and third windows. The second cylindrical portion selectively connects the inlet window to the first window. The spool is movable between first and second positions relative to the first, second and third windows to regulate flow. The first and second cylindrical portions respectively includes first and second widths. A first ratio corresponds to the first width to the spool diameter and a second ratio corresponds to the second width to the spool diameters. The first ratio is between 1.83 and 1.93 and the second ratio is between 1.22 and 1.32.

  • Patent number: 9303784
    Abstract: An apparatus and method for controlling a pressure drop of a fluid is disclosed. A sleeve includes a plurality of flow passages in a wall of the sleeve. A member slides relative to the sleeve to reveal at least a portion of the plurality of flow passages to control flow of the fluid through the flow passages. The plurality of flow passages are at azimuthally-and axially-staggered locations around the sleeve.

  • Patent number: 9249800
    Abstract: A bypass directional control valve has a valve sleeve, and two sets of outlet ports on each of two axial sides of the inlet ports. The outlet and the inlet ports all are formed to be cylindrical holes, and a diameter of the inlet ports is greater than a diameter of the outlet ports. A valve sleeve, a spool, a fluid flow system and a method are all also disclosed.

  • Patent number: 9212608
    Abstract: A method of metering fuel with a fuel valve. The method includes arranging a spool within to a sleeve along an axis, wherein the spool includes four seal lands. The sleeve includes a fuel inlet aperture, a fuel outlet aperture, and a shutoff port. A first cavity and a second cavity are defined between the spool, the sleeve, and subsets of the seal lands. The fuel inlet port and the fuel outlet port abut one such cavity. Sliding the spool along the axis results in the fuel outlet aperture extending longitudinally beyond the second seal land in the upstream direction.
