Air nozzles are used in carburetors, in internal combustion engines. They provide suitable fuel blends at various working regimes of these engines, fuller burnout of the fuel blend, and a reduced fuel expenditure and toxicity of the burned out gases. The nozzle comprises a bush (6), connected to a body (1), which contains a sub-spring spring (2), a piston (3) connected to a needle with variable section (5), and directed to the bush (4). In the body, there is a driving opening "a" in its above-piston part and suction openings "b" in its sub-piston part.
