摘要： A control valve includes particle and moisture accumulation inhibiting features. The control valve includes a piston that provides for pressure communication to a back cavity through a tortuous path that settles out particle matter carried within the airflow. Moreover, the piston includes drainage openings that direct moisture out of piston and away from the sealing surfaces.

摘要： An example filter assembly prevents particles from entering a control valve and defines an airflow path between an inlet and outlet. An inlet tube extends from an inlet and defines an inlet passage into a filter housing. Openings within the inlet tube open into an interior space of a filter housing. An outer housing defines a cavity within which the filter housing is secured. The filter housing includes an open top portion that engages a cap that covers and seals the outer housing. The cap holds the filter housing to prevent movement of the filter housing.

摘要： A thrust bearing for a rotary machine includes first, second and third layers. The second layer includes a corrugated foil arranged between the first and third layers. The corrugated foil includes a wall having peaks engaging the first layer and valleys engaging the third layer. A depression is arranged in the wall between first and second peaks. The depression is spaced from the first and third layers. The first layer includes multiple arcuate top foils that are arranged adjacent to a thrust runner of a rotatable shaft. A corresponding number of arcuate corrugated foils may be used to support the top foils. The third layer, which is provided by an annular main plate, includes multiple arcuate spacers arranged circumferentially on the main plate. The spacers are generally aligned with a trailing edge of the top foils. The depressions decrease the stiffness of the bump foils. The spacers direct the axial load through the thrust bearing in a desired manner.

摘要： A hydrodynamic bearing is provided that includes an annular main foil having axially spaced inner and outer surfaces. Bump foils are supported circumferentially on the outer surface. Top foils are supported circumferentially on the inner surface opposite the bump foils. In one example, spacers are arranged between the top foils and the main foils. The spacers can be provided by chemically etching the main foil, in one example. The bump foils include first and second corrugated portions respectively providing first and second axially heights. The first axial height is less than the second axial height and is arranged at a leading edge of the bump foil relative to the direction of airflow across the hydrodynamic bearing.

摘要： A motor includes a housing including separate motor and bearing cooling inlets. A motor is arranged within the housing and includes a stator and rotor assembly that is supported on air bearings. The motor cooling inlet is in fluid communication with the stator, and the bearing cooling inlet is in fluid communication with the air bearings. A vent is arranged in the housing and is common to the motor and bearing cooling inlets. The vent is in fluid communication with a low pressure side of a ram air duct. The bearing cooling duct is in fluid communication with a high pressure side of a ram air duct, such as through a reverse J-tube. A differential pressure between the high and low pressure sides moves cooling fluid from the bearing cooling inlet to the vent to cool the bearings.

摘要： A diffuser includes multiple vanes rotatable about pivot pins between multiple positions. A mounting plate supports a backing plate. The vanes are arranged between the backing plate and the shroud. The pivot pins are in a slip fit relationship with the backing plate, vanes and shroud and are threadingly received by bosses in the mounting plate. The mounting plate and pivot pin arrangement better enables the backing plate and shroud to remain parallel with one another during deflection of the backing plate and/or shroud. Structure, such as integral protrusions and/or bolts, extend from between the backing plate and shroud through apertures in the vanes to better contain the vanes in the event of a catastrophic failure.

摘要： A diffuser is provided having a spaced apart shroud and backing plate. A diffuser vane is provided between the backing plate and shroud. The vane includes first and second sealing surfaces opposite from one another and adjacent to the backing plate and shroud. Leading and trailing surfaces are arranged opposite from one another and adjoin the first and second sealing surfaces. The first sealing surface includes a first protrusion extending therefrom approximate to the leading surface with a gap extending from the trailing surface to the first protrusion. The second surface includes a second protrusion extending therefrom proximate to the trailing surface with a second gap extending from the leading surface to the second protrusion. The surfaces provide four corners such that the protrusions are arranged on opposite corners from one another to create a pressure differential between the first and second sealing surfaces.
