Beschreibung
Zusammenfassung:	A system (S) for supplying fuel (C) to the combustion chamber (5) in an aircraft turbine engine (6), comprising injectors (1) comprising a first pilot stage (10), a second pilot stage (16) and a main stage (13), the pilot stages (10, 16) being configured to supply a permanent flow of fuel (C), the main stage (13) being configured to supply an intermittent flow of fuel (C), a device (2) for distributing the fuel (C) to the injectors (1), comprising a primary circuit (21), a secondary circuit (22) and a valve (20) which is configured to distribute the fuel (C) between the primary circuit (21) and the secondary circuit (22), the primary circuit (21) being connected to the first pilot stage (10) and the main stage (13), the secondary circuit (22) being connected to the second pilot stage (16), and a control unit (3) for controlling the valve (20). Un système d'alimentation (S) en carburant (C) de la chambre de combustion (5) dans un turbomoteur d'aéronef (6), comprenant des injecteurs (1) comprenant un premier étage pilote (10), un second étage pilote (16) et un étage principal (13), les étages pilotes (10, 16) étant configurés pour délivrer un débit permanent de carburant (C), l'étage principal (13) étant configuré pour délivrer un débit intermittent de carburant (C), un dispositif de répartition (2) du carburant (C) dans les injecteurs (1) comprenant un circuit primaire (21), un circuit secondaire (22) et une vanne (20) configurée pour répartir le carburant (C) entre le circuit primaire (21) et le circuit secondaire (22), le circuit primaire (21) étant relié au premier étage pilote (10) et à l'étage principal (13), le circuit secondaire (22) étant relié au second étage pilote (16), et un organe de commande (3) de la vanne (20).
