FIELD: mechanical engineering; turbomachines.
SUBSTANCE: fuel system of turbomachine combustion chamber has fuel-feed nozzle providing spraying of fuel in combustion chamber, and mixing-and-deflecting unit arranged symmetrically relative to axis of fuel-feed nozzle and designed to form mixture of fuel oxidizer with fuel and its atomizing in said combustion chamber. Mixing-and-deflecting unit has first swirler and, at least, second swirler arranged with relative displacement along said axis and separated by venture device arranged coaxially relative to fuel-feed nozzle. First swirler is rigidly fastened to said fuel-feed nozzle and is arranged at constant distance from nozzle in radial direction. Distance is chosen so that fuel atomized by fuel-feed nozzle cannot get onto said first swirler.
EFFECT: provision of good atomizing of fuel under all conditions.
