摘要： A device for priming an empty or partially full burner manifold of a gas turbine engine with fuel before it is required to supply from the burner manifold to the associated burners comprises a fuel accumulator and a control valve.A fuel pressure signal supplied to the control valve terminates the supply of relatively high pressure fuel to the fuel accumulator via the control valve. A metered quantity of fuel is supplied via the control valve to the burner manifold from the fuel accumulator by the motive force of a spring acting on a piston in the accumulator. The metered quantity of fuel is supplied via the control valve to the burner manifold, to fill the burner manifold and to prevent undesireable drops in the quantity of fuel being supplied to other manifolds when the regulated fuel is supplied to the burner manifold.
