Beschreibung
Zusammenfassung:	The invention relates to a fuel supply system of a turbomachine, including a fuel circuit having a pressurizing means at the outlet of the circuit, a pump arranged to send a flow of fuel into the circuit, and a flow sensor placed in a fuel supply duct between an outlet of the pump and the pressurizing means. The fuel circuit includes a device for regulating a flow cross section between the pump and the flow sensor, the device being activated by control means, the shaft of the pump being associated with detection means recording a speed of rotation of the shaft, and, if these detection means record a speed of rotation above a variable predetermined threshold, the regulating device is activated in order to reduce the flow sent to the flow sensor.
