FIELD: mechanical engineering.
SUBSTANCE: invention relates to systems providing fuel injection into combustion chamber of turbomachine. Proposed fuel injection system contains N fuel nozzles arranged in combustion chamber of turbomachine and supplied with fuel from fuel tank, and pumping unit built between nozzles and tank and containing set formed by drive shaft with N driving gears of one diameter, driven shaft with N driven gears of one diameter and sealing partitions arranged crosswise between two adjacent gears of drive and driven shaft to form zones of fuel intake and zones of fuel delivery located at both sides from longitudinal plane passing through longitudinal axes of driven and driven shafts. Set is installed in housing containing intake fuel hole communicating with tank and open to one fuel intake zones, and fuel delivery holes, each being opened to one of fuel delivery zones to supply each fuel nozzle.
EFFECT: simplified hydraulic part of system by reducing number of units used in system, provision of convenient control of metered out fuel flow rates through nozzles.
