Abstract

The invention relates to the field of jet technology. The surface area of the minimal cross-section of the mixing chamber represents from about 1.1 to about 7.98 times that of the minimal cross-section of the active liquid nozzle. A liquid-gas jet apparatus with the above described correlation of sizes has a higher efficiency due to reduced energy losses.

Claims

1. A liquid-gas jet apparatus, comprising an active liquid nozzle and a mixing chamber, wherein a ratio of the surface area of the minimal cross-section of the mixing chamber to the surface area of the minimal cross-section of the active liquid nozzle is within the range of about 1.1 to about 7.98.

2. A method for increasing the efficiency of a liquid-gas jet apparatus, having an active liquid nozzle and a mixing chamber, for evacuating a gaseous medium by kinetic energy of a liquid medium, comprising:

making the liquid-gas jet apparatus wherein a ratio of the surface area of the minimal cross-section of the mixing chamber to the surface area of the minimal cross-section of the active liquid nozzle is within the range of about 1.1 to about 7.98.
