Abstract: The invention is directed to air-liquid atomizing nozzles, particularly for electrostatic paint spray systems. The nozzle of the invention is characterized by having an annular liquid discharge opening closely surrounded by an annular air discharge opening. The arrangement of the air discharge opening is such that the air, while being discharged in a generally cylindrical flow, is caused and permitted immediately to contract in diameter in front of the nozzle, and thereafter to gradually expand in diameter to form a desired paint spray pattern.
