Including Working Fluid Force Responsive Vane Or Flow Control Patents (Class 415/146)
  • Patent number: 11035380
    Abstract: This diffuser vane (60), of which a blade height direction is aligned with an axial direction, has an airfoil shape in cross section orthogonal to the blade height direction, and comprises a body which, starting from a leading edge at the end on the radially inner side toward the radially outer side, extends toward the front side in an impeller rotating direction (R) and reaches a trailing edge at the end on the radially outer side. In the body of the diffuser vane, the turning angle of a shroud-side blade shape (S) that is the airfoil of an end face on one side in the axial direction is different from the turning angle of a hub-side blade shape (H) that is the airfoil of an end face on the other side in the axial direction. The airfoils form a transition continuously between the shroud-side blade shape and the hub-side blade shape. The turning angle of the hub-side blade shape is smaller than the turning angle of the shroud-side blade shape.

  • Publication number: 20140064908
    Abstract: An exemplary valve device for controlling flow of a turbomachine fluid includes a housing having a first inlet at a first elevation, a second inlet at a second elevation higher than the first elevation, and an outlet. A flow control member is within the housing. The flow control member in a positive g-force environment is biased toward a first position that permits flow through the first inlet to the outlet. The flow control member in a negative g-force environment is biased toward a second position that restricts flow through the first inlet to the outlet.

  • Publication number: 20140037422
    Abstract: A system and method for rapid pressurization of a motor compartment and cooling system during a shutdown, a surge, and/or other situations in which the suction pressure significantly varies. A motor/compressor arrangement includes a seal gas system fluidly communicating with the motor compartment via a motor pressurization line, with the outlet of the compressor, and with a shaft seal. A motor pressurization valve is coupled to the motor pressurization line and a controller is configured to open the motor pressurization valve at start-up of the motor-compressor to supply seal gas to the motor compartment and to pressurize the motor compartment when a difference between the seal gas supply pressure and the suction pressure is indicative of the seal gas supply pressure being insufficient.

  • Publication number: 20130028705
    Abstract: An active clearance control system utilizes a working fluid stream to control radial thermal growth and thereby a clearance between turbine blades and a corresponding shroud of a gas turbine engine. Conduits disposed about a turbine case and proximate to pads defined within the turbine case include a flow surface parallel to the pads. The pads are an area of increased thickness in the turbine case that receives impingement flow from the conduits. Grooves within the pads further increase impingement cooling flow effectiveness. The increased thickness of the pads provides the thermal mass desired to effect thermal expansion and contraction responsive to the cooling airflow.
