  • Manually operated metering valve for a fuel control
    Patent number: 4344281
    Abstract: A fuel control having an electrically operated metering valve and a manually operated metering valve through which fuel is independently scheduled to an engine. During normal operation, the electrically operated metering valve controls the flow of fuel to the engine in response to an operator input signal. However, should an electrical failure occur, the manually operated metering valve is activated to schedule fuel to the engine. The manually operated metering valve has a pressure responsive member that receives an input signal representative of the discharge pressure of a compressor in the engine to prevent surging during acceleration.

  • Fuel control for gas turbine engine
    Patent number: 4033112
    Abstract: Fuel control apparatus including a fuel conduit connected to receive pressurized fuel from a fuel pump and provided with fuel servo actuated metering valve means therein for controlling the rate of fuel flow therethrough to an engine. The fuel servo actuated metering valve is actuated by a fuel servo piston pressurized by a servo valve controlled fuel pressure differential derived from a predetermined fuel pressure differential maintained by a pressurizing valve downstream from and in series flow relationship with the metering valve. The metered fuel flow for actuating the servo piston is extracted from the fuel conduit upstream from the pressurizing valve and returned to the fuel conduit downstream from the pressurizing valve.
