mechanical engineering. SUBSTANCE: fuel- injector device has main axle, reverse-flow zone, fuel injector, and inlet zone positioned along main axle between fuel injector and reverse-flow one. Vortex flow of fuel may be created in inlet zone. Reverse-flow zone has circular space adjacent to inlet zone. This space narrows in direction of inlet-zone flow and turns into reverse-flow line. Device provides for enhanced accuracy of adjustment of fuel supply to burner. EFFECT: simplified construction. 4 cl, 4 dwg
