    Disclosed herein is a carburetor for an internal combustion engine embodying a novel air control valve in which the air is admitted from a plurality of radially disposed apertures. Air flow is controlled by a like plurality of movable shutters attached to a movable cage assembly circumscribing the carburetor housing. The carburetor also embodies vacuum valves which generate vacuum signals for the engine's spark advance and exhaust gas recirculating mechanisms as a function of the engine's manifold vacuum and the position of the cage assembly. In the preferred embodiment, the cage assembly is a rotary cage.

    (54) CARBURETTOR FOR INNER MOTOR The invention relates to the field of engine construction, in particular to carburetors for an internal combustion engine. Carburetors for an internal combustion engine are known, comprising a housing, a valve located on the axis of rotation with a casing for controlling the air flow, provided with inlet openings made on the casing, shutter elements for controlling the opening degree of the openings located at the intake openings an orifice located along the axis of the valve; and a fuel supply device installed in the casing 1. A disadvantage of the known device is that air through TfOK in the immediate vicinity of the valve is asymmetrical, especially when the opening angle of the valve is very small. Asymmetrical air flow adversely affects the distribution of the air / fuel mixture in the intake manifold of the engine. Such a disturbance in the distribution of the combustible mixture leads to an increase in fuel decomposition and an increase in the toxicity of exhaust gases. COMBUSTION The aim of the invention is to improve the mixing of the fuel with air. The goal is set by the fact that the inlet orifices are made radially relative to the axis of the valve to direct air flow towards the center of the casing, and also that the closure elements are placed between the casing and the casing, and the casing is installed with the possibility of angular movement relative to the casing of the valve. Fig, 1 shows a carburetor, side view; fig 2 is the same, top view. The carburetor contains a base 1, on which case 2 is installed. A turn-on casing 3 encloses the case 2 from above and on the side, and is fed to the carburetor using a regulating fuel device 4 according to a signal from the control unit 5 with fuel supply. The housing 2 is attached to the base 1 by means of fasteners-blocks 6. The rotary casing 3 is moved by the action of an actuator controlled from the fuel supply pedal 7. The movement of the pedal 7 is transmitted to the cable 8, - having a linearly movable wire core 9, at one
