Title: SYSTEM FOR SUPPLYING FUEL TO A TURBOMACHINE
Abstract:
The invention relates to a system for supplying fuel to a turbomachine, comprising a fuel circuit comprising a pressurisation means (202) at the outlet (3) of said system, and a pump (1). The circuit comprises a flow rate sensor (201) arranged between the outlet of the pump and the pressurisation means, the flow rate sensor (201) comprising a sliding drawer (211), a restoring means (206), and a sensor (212) for detecting the position of said drawer in order to indicate the flow passing through the flow rate sensor (201), the system comprising a device (6') arranged to as to drive the pump with a controllable rotational speed and means (4') arranged so as to control the device on the basis of a measurement supplied by the flow rate sensor, in such a way as to adapt the rotational speed of the pump shaft.
