Abstract
A detection method of a breakdown of a pressure relief valve of a fuel injection circuit for a turbomachine, the injection circuit including a low pressure stage and a high pressure stage, the low pressure stage having an inlet and an outlet, the high pressure stage having an inlet and an outlet, the low pressure stage being connected to the high pressure stage, the pressure relief valve being connected in parallel with respect to the high pressure stage, the injection circuit further including a recirculation loop including an inlet connected to the outlet of the high pressure stage and an outlet connected to the outlet of the low pressure stage, the method including measuring a differential pressure in the injection circuit.
