Patents by Inventor Edward F. Cole

Edward F. Cole has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Multiple function fuel valve and system
    Patent number: 5020315
    Abstract: A floating piston (54) has a valved (86) vent opening (88), with the vent opening closing (92) on movement of the piston. The piston is spring loaded (56, 58) to vent air, but seal fuel. Modulation of pressure in pressure resisting chamber (48) between pump discharge and lower pressures, provides control of the valve. Pressure difference (96, 62) and valve position (36) measurements provide flow measurement data.

  • Centrifugal main fuel pump
    Patent number: 4607486
    Abstract: A high speed centrifugal fuel pump delivers fuel to the main metering valve of a fuel control of a gas turbine engine for feeding the engine's burners, and a boost pump and positive displacement pump pressurize fuel for the servo medium for actuating the various valves and engine geometry actuators. The boost pump also assures that the vapor/liquid flow relationship satisfies the engine's requirements.

  • Automatic vent for fuel control
    Patent number: 4449359
    Abstract: This invention relates to the fuel system of a gas turbine power plant and modifies a conventional fuel control to automatically vent trapped air contained in the fuel control and fuel distribution system into the engine's burners by bypassing the conventional minimum pressure and shut off valve. This serves to prime the main fuel pumps when running dry during the switching of one fuel tank to another.

    Inventors: Edward F. Cole, Dean H. Crombie
  • Fuel heating system for gas turbine engine
    Patent number: 4354345
    Abstract: To accommodate fuel having higher freezing points the continuous bypass flow of fuel from the fuel control is selectively diverted to pick up the rejected heat from the engine's lubrication system to heat the fuel in the aircraft fuel tank.

    Inventors: Raymond A. Dreisbach, Jr., James G. Griffin, Edward F. Cole
  • Fuel collecting and recycling system
    Patent number: 4206595
    Abstract: This system serves to collect and recycle fuel leftover in the fuel manifold and fuel distribution system of a gas turbine power plant when it is shutdown and operates in conjunction with the power plant's existing fuel control.
