FIELD: engines and pumps.
SUBSTANCE: fuel injection device for the ring combustion chamber of the turbo-machine contains a control loop constantly feeding the injector with the outlet to the first Venturi tube, and a multipoint loop. The multipoint loop periodically feeds injected holes made on a frontal surface of the forward ring chamber of the second Venturi tube, coaxial to the first Venturi tube and enclosing it. The ring rim is mounted in the ring chamber to form in it of the loop for fuel supply to the injection holes, and cooling loop by means of passing of fuel supplied to the injector of the control loop. The cooling loop passes along the frontal surface of the chamber in the immediate proximity from the injection holes.
EFFECT: invention is aimed at minimizing of coking of fuel circulating at the level of the frontal plane of the ring chamber.
