ABSTRACT:
A device to regulate the flow of a fuel supply system for a gas turbine engine, said system being of the type comprising a volumetric pump, a flow regulator element in the outlet of the pump and a return circuit for the fuel connecting the outlet of the pump upstream from the regulator element with the inlet of the pump. The device includes a second flow regulator element in the fuel return circuit and an arrangement of elements to control the passage cross section of the regulator element so that the pressure drop of the liquid fuel at the passage of the first regulator element remains proportional to the discharge pressure of a suitably chosen stage of the air compressor of the engine.
