Patent ID: 8857150

Claim:
A device for monitoring a high-pressure pump in a turbine engine fuel supply circuit, the circuit including a pressurizing and shut-off valve that is mounted at a flow outlet of a fuel metering valve and at a flow inlet of a supply duct of the injectors, and means for measuring rotational speed of the turbine engine, the device comprising: means for detecting an opening of the pressurizing and shut-off valve; means for recording a measured value of the rotational speed of the turbine engine at opening of the pressurizing and shut-off valve; and means for comparing the measured value with a predetermined threshold, to propose replacement of the high-pressure pump when the recorded value of the rotational speed reaches the predetermined threshold, wherein the pressurizing and shut-off valve remains in a closed position and prohibits the supply of the fuel to the injectors as long as a pressure of the fuel at the outlet of the fuel metering valve is less than a predetermined pressure threshold, and is in an opened position otherwise.
