  • Screw pump and impeller fan assemblies and method of operating
    Patent number: 10240609
    Abstract: An impeller fan assembly that includes a housing, a stator, a rotor having a hub and an annular array of non-stationary blades extending from the hub, at least two spaced apart bearings mounted to the stator, and a pump in fluid communication with the bearings to provide fluid to the bearings. A screw pump is provided within the hollow portion of the shaft. Inlet of the screw pump is fluidly coupled to the sump and outlet is in fluid communication with the bearings. Rotation of the screw pump pumps fluid from the sump to the bearings. A de-swirler is provided within the sump to reduce rotational movement of the fluid within the sump. The de-swirler has a hub with fixed curved vanes extending from the centerline of the hub. The curved vanes have curvature in a direction opposite from a rotational direction of the screw pump.

  • Valve assembly and method of controlling flow of fluid
    Patent number: 9611947
    Abstract: A valve assembly includes a plenum having first, second, and third air source ports, a flapper valve assembly pivotally movable between a first position, where the first air source port is closed by the flapper valve assembly and the second and third air source ports are open and in fluid communication, and a second position, where the second air source port is closed by the flapper valve assembly and the first and third air source ports are open and in fluid communication and a method of controlling fluid flow via a valve assembly.
