Abstract
This invention relates to the area of jet technology, primarily to liquid/gas ejector devices used for the creation of a vacuum. The technical problem, solved by the invention, is the increase of the coefficient of efficiency of the liquid/gas vacuum ejector device. This problem has been solved by this invention due to the optimization of the process of mixing gas and liquid media. This has been achieved due to the optimization of mixing gas and liquid media in the mixing chamber of the liquid/gas vacuum ejector device, containing an active nozzle (1) and a mixing chamber (2), the area of the minimal section of the latter being 201 to 800 times the area of the minimal section of the active liquid nozzle (1), and the ratio of the distance from the outlet section of the mixing chamber (2) to the outlet section of the active nozzle (1) to the diameter of the minimal section of mixing chamber (2) is in the range from 10 to 300.
