Claim:
A system for injecting fuel into a turbomachine having N fuel injectors placed in a combustion chamber of the turbomachine and fed from a fuel tank, the system further comprising, interposed between said N injectors and said tank, a single pumping means for taking fuel from the tank and delivering N metered fuel flows to the injectors, wherein said single pumping means comprises an assembly formed by: a drive shaft having a longitudinal axis and fitted with N same-diameter drive gears: a driven shaft of longitudinal axis parallel to the longitudinal axis of the drive shaft. provided with N same-diameter driven gears meshing with said N drive gears; and N-l sealing partitions placed transversely between pairs of adjacent gears on the drive and driven shafts so as to define N fuel admission zones and N fuel delivery zones situated on either side of a longitudinal plane containing the longitudinal axes of the drive and driven shafts, said N fuel admission zones communicating with one another via holes pierced through the sealing partitions; said assembly being fitted longitudinally in leaktight manner in a cylindrical body having at least one fuel admission orifice connected to the tank and opening out into any one of the admission zones, and N fuel delivery orifices each opening out into a respective one of the N fuel delivery zones to feed each of the N injectors.
