    A carburettorfor engines of motorvehicles has a suction conduit (1) fed by fuel from a chamber (3) in which the fuel level is kept constant by a needle valve actuated by a float system with two floats (14, 15), the walls (5, 6, 7, 8) which delimit the chamber (3) laterally are vertical and vertical are the outer surfaces of the two floats (14,15), particularly those facing the walls of the chamber (3), on the vertical line passing through the centre of gravity (33) of the figure (39) defined by sectioning a horizontal plane by the spatial figure included between the inner walls of the chamber (3) and the outer surfaces of the floats (14,15) there is the main jet which is supported by a columnar structure having vertical walls, suspended from the cover of the carburettor, and which accommodates the main and idling circuits of the carburettor; the planes of the level of the fuel contained in the chamber section the floats according to figures whose static moments relative to the fulcrum of the closure lever of the needle valve are substantially constant as the inclination of the carburettor relative to the horizontal plane varies.

    1 The invention relates to engineostroilt, in particular, to carburetors for an internal combustion engine. The aim of the invention is to improve the reliability of the carburetor. FIG. 1 shows a carburetor for,.,. internal combustion engine with an open low-angle camera, top view; in fig. 2, section A-A in FIG. one; pas figs. 3 shows a section BB in FIG. one; in fig. 4 — torus cap; in fig. 5, view B in FIG. 4. The carburetor for an internal combustion engine comprises a housing 1 with a flow channel 2 and a float chamber 3 arranged against the latter, which is made with a flat bottom 4 (FIG. 2) and vertical side walls 5-8, inside which a float system is installed that supports a constant fuel level and equipped with a pivoting lever 9 mounted on a fixed axis 10, and a lid 11 of the float chamber 3 (Fig. 3), made with one flat surface 12, which bounds the inner cavity 13 of the bottom chamber 3. The rotary lever The g 9 is rigidly connected with two floats 14 and 15, with the first float 14 having two float elements 16 and 17 interconnected by a jumper 18, and the second float 15 having two float elements 19 and 20 interconnected by a jumper 21. The sliver 18 of the float 14 is arcuate; it is arcuate and surrounds the boss 22 without touching it, and a hole 23 is made in the boom 22 for the fastening element (not yet). The jumper 21 of the second float 15 has arcuate recesses 24 and 25, both are equipped with equivalent pop shops 14 and 15. The float element 16 of the float 14 and the float element 20 of the float 15 are located relative to axis 10 further than the float elements 17 and 19, and the sequence is made with a large immersion volume than the float i elements 16 and 20. As can be seen from FIG. 4, the krppka 11 has a protrusion obrazdenny into the internal cavity 1.3. the float chamber 3 and made in the form of a columnar element 26 with an emulsion well 27, with a main fuel jet 28 and an emulsion tube (not shown) installed in the projection, with the axes of the emulsion tube and the main fuel jet 28 arranged on a vertical line, passage. through the center of gravity of the flat figure, the image of the surface of the mirror 29 of the fuel in the float chamber 3 when the carburetor is horizontal, and also lie in the outermost height. 0 symmetry passing through the axis of this flat figure. The lid 11 also has a fuel valve 30, which interacts with a pivoting lever 9, and a sleeve 31, is made of a polymer material and is located co-centrically to the fuel valve 30, and the sleeve 31 is made with an end surface 32 coinciding with the plane of the flat surface 12 of the cover 11. The latter has a sleeve-like element 33, the intruding cavity of which forms the inlet part 34 of the flow channel 2, and the cover 1, the column-shaped element 26 and the sleeve-shaped element 33 are made as an e / din piece having racks 35 for fastening The fixed axis 10 of the pivot arm 9 and the recesses 36 and 37 (Fig. 5) in the lid 11 have the same configuration as the configuration of the opposite parts of the internal cavity 13 of the float chamber 3. The housing 1 is made with a boss 38 having an opening 39 for fixing element (t} e shown), and with the boss 40, which has a channel 41 of the carburetor dosing systems. The housing 1 has a diffuser 42 for the flow channel 2. The outer surface 43 of the columnar element 26 is vertical, and the recesses 36 and 37 of the curl are limited to a flat surface 12 and have vertical side walls. The work of the carburetor is as follows. When the engine is mounted on a vehicle, the latter experiences more acceleration in the longitudinal and transverse directions, and a change in inclination occurs when moving uphill or downhill (such as in high-traffic vehicles). However, the fuel level in the emulsion well 27 remains constant (disregarding the operating mode of the engine), as the axes of the main fuel jet 28 and the emulsion tube lie on a vertical line passing through the center of the body of the 1-piece figure formed by the fuel mirror, and due to the configuration The internal cavity 13 of the float chamber 3 and the floats 14 and 35 do not displace the center of gravity of this figure when the above factors influence the vehicle. At the same time, the floats 14 and 15 create a constant force on the fuel valve 30. Although the degree of immersion of the float elements 16, 17, 19 and 20 is also variable, but due to the itx of different heights and distances to the axis 10 (as indicated) a constant force is provided to the fuel valve 30 from the pivot arm 9. This provides a constant ::.
    The volume of fuel in the float chamber 3, the surfaces of the bottom 4, the cover 11 and the side walls 5-8 ensure that the center of gravity of the flat figure of the mirror 29 is in line with the axes of the emulsion tube and the head 19 of

    28 fuel supply. All this provides increased carburetor reliability, and the float chamber 3 of the carburetor can be located on either side 5 of the flow channel 2. Regarding the direction of movement of the vehicle
