Beschreibung
Zusammenfassung:	The invention proposes a system for supplying (10) fuel to an aircraft turbomachine, which includes a low-pressure circuit (14) in which a low-pressure pump (12) is installed, and a high-pressure circuit (44) supplying an injection device (20) of the turbomachine and actuators (22) of components of the turbomachine, which includes several high-pressure pumps (30, 32), characterised in that each of the said high-pressure pumps (30, 32) consists of a stage of a high-pressure pump with several stages, each stage of the said pump with several stages being associated with each of the said segments (24, 26).
