A liquid-gas ejector comprising a nozzle and a mixing chamber is disclosed, wherein the distance between the outlet section of the nozzle and the inlet section of the mixing chamber of a liquid-gas ejector is determined from the following formula:whereL-distance between the outlet section of the nozzle and the inlet section of the mixing chamber (mm);k-design factor, ranging from 0.001 to 0.3;alpha-ratio of the surface area of the minimal cross-section of the active nozzle to the surface area of the minimal cross-section of the mixing chamber;G-liquid flow rate through the nozzle (g/sec);mu-coefficient of resistance of the nozzle (g/sec*mm2), amounting from 0.5 to 1.1. A liquid-gas ejector realized according to the above-mentioned formula exhibits a higher efficiency factor.
