    Abstract: A fuel circuit for a turbine engine is provided. The fuel circuit includes a fuel return valve connected to the main circuit and to a fuel tank, the valve being capable of adopting an open position in which the valve allows an excess quantity of fuel to be returned to the tank, and a closed configuration in which the return of fuel to the tank is blocked; a first hydraulic line connecting the valve to the main circuit, and including a first filter; a second hydraulic line connecting the valve to the main circuit, and including a second filter; and an intermediate hydraulic line connected to the first and second lines downstream from the filters, the first and second lines being hydraulically connected together by the intermediate line when the valve is in the closed configuration.

    Abstract: A fuel supply system for a gas turbine engine including first and second positive displacement pumps operated simultaneously to supply fuel under pressure from a low pressure source, a combining spill valve controlling the output flows from the first and second pumps to combine the outputs of the first and second pumps for supply to a metering valve of the system, or to spill some or all of the output of one or both pumps back to the low pressure supply, a pressure raising and shut off valve arrangement downstream of the metering valve for isolating the fuel system from an associated engine until the fuel pressure upstream of the pressure raising and shut off valve arrangement exceeds a predetermined pressure, and, a control system dependent upon the position of the combining spill valve for reducing said predetermined pressure at which said pressure raising and shut off valve arrangement opens.

    Abstract: A multiple fluid feed system for, for example, a turbine engine, comprises a fuel tank, a fuel pump, and means for switching fuel flow from said pump between a return to tank condition and an engine supply condition. A starting fuel reservoir has a cylinder with a fuel inlet and a fuel outlet. A piston in the cylinder is movable from a start position to a run condition in response to movement of the switching means from the return to tank condition to the engine supply condition. A supply of starting fuel is disposed in the reservoir and is biased out of the reservoir upon initial movement of the piston.

    Abstract: A device and method are disclosed to reduce the self-heating of the fuel in an aircraft turbojet engine fuel system by inducing cavitation in a positive displacement pump in the system. The cavitation is induced by modulating the charging or inlet pressure of the pump by the action of a modulating or regulating valve placed in the pump inlet line.
