A nozzle is known, containing a cylindrical mixing chamber, at the back end of which a teat nozzle is installed, and in the side wall there are air polishers / perpendicular airfoil and chamber length J and igniter IJ. A disadvantage of the known FORMARKER is low cost due to the high energy consumption required for the supply of air. The purpose of the invention is to increase efficiency by reducing energy consumption for air supply and simplifying the design. The goal is achieved by the fact that in the nozzle containing a cylindrical mixing chamber, in the back end of which there is a fuel nozzle, and in the side wall there are holes for air supply, distributed around the perimeter and length of the chamber, and the igniter, behind the mixing chamber, an additional shell is installed, in the cavity of which, near the output slice of the chamber, a zapalnik is placed, made in the form of a glowing body, the axis of the holes in the side wall of the chamber are inclined to one side at an angle of 1060 to the radius of the chamber and their number is 3-20, preferably 13. In addition, the ignition body of the igniter can be made in the form of a spiral placed along an arc with the opening angle of 30-330 at a distance of 0.005-0.03 ft from the output slice camera mix Moreover, the shell can be supplied at notches located along its perimeter in a checkerboard pattern. FIG. 1 shows the proposed nozzle, a general view; in fig. 2 — the mixing chamber (enlarged) f in FIG. 3 is a section A-A in FIG. 2 in FIG. 4 - forelock with inyl execution of igniter, option; in fig. 5 is a section along the line B – B in FIG. 4 in FIG. 6 a nozzle with an inelm version of the mixing chamber and a shell, (a variant in Fig. 7 - a shell sweep; in Fig. 8 - a nozzle with another shell installation option. The nozzle contains a cylindrical mixing chamber 1, the fuel nozzle 2 is installed in the rear end of the office, and the side wall has openings 3 for supplying air, distributed around the perimeter and length of chamber 1, and a pilot light 4. Behind the mixing chamber 1, an additional shell 5 is installed in the cavity, which has a pilot light 4 located in the form of a glow body one, the axes of the holes 3 are inclined to one side at an angle of 1060 at the radius of chamber 1, and their number is 3-20, preferably 13. The pilot light 4 can be made in the form of a spiral b, placed along an arc with the angle of the latter, 30-330, at a distance of 0, ..., 03 m of the output slice of the mixing chamber 1, and the shell 5 may be provided with notches 7, spaced along, its pershletra in a checkerboard pattern. The fuel nozzle 2 is connected by a fuel line 8 to a tank 9 equipped with - after-runner 10. Hole 3 d-, air supply communicated with the collector rum .11 connected to the blower 12. The nozzle 2 is equipped with an electromagnetic regulator 13 with a coil 14, a core 15, a needle 16 and a SPRING 17. An Ionization sensor 18 serves to control the presence of a flame. When the Injector operates, the fuel heated in the tank 9 by the heater 10 is supplied through the fuel line 8 through the flow controller 13 to the fuel nozzle 2, from where it flows into the mixing chamber 1. Air is supplied through the openings 3 in the side wall of the mixing chamber 1. Since the apertures 3 are located inclined at an angle to the radius of the mixing chamber 1, a vortex forms in it, whereby the fuel is sucked into the chamber 1, is intensively sprayed and ignited by the igniter 4 at the exit of the chamber 1. an angle of 10-60 to 1 in the rear of the mixing chamber, and also due to the choice of the optimal number of holes, the energy loss per air supply is significantly reduced, which increases the efficiency of the nozzle.
