A fuel metering device in a turbine engine, mounted betwen a high-pressure pump (14) which draws out the fuel fronm a fuel tank (16), and a plurality of fuel injectors (20) disposed in a combustion chamber in the turbine engine, characterized in that it includes a metering device (22) which receives, at a pression P1, the fuel to be injected from a regulator valve (34) and delivers it, at a pressure P2, to the plurality of injectors through a blocking valve (26), the regulator valve recirculating the fuel towards the high-pressure pump, according to the difference (P1- P2) of pressures detected directly at the ports of the metering device and injected at its two end inputs (36A, 36B).
Dispositif de dosage de carburant dans une turbomachine, monté entre une pompe haute pression (14) qui soutire le carburant d'un réservoir de carburant (16) et une pluralité d injecteurs de carburant (20) disposés dans une chambre de combustion de la turbomachine, caractérisé en ce qu'il comporte un doseur (22) qui reçoit, à une pression P1, le carburant à injecter d'une soupape de régulation (34) et le délivre, à une pression P2, à ladite pluralité d'injecteurs au travers d'un clapet d'arrêt (26), ladite soupape de régulation assurant une re-circulation du carburant vers ladite pompe haute pression en fonction de la différence (P1- P2) des pressions prélevées directement aux bornes du doseur et injectées ses deux entrées d'extrémité (36A, 36B).
