MULTI-NOZZLE GAS EJECTOR Russian patent published in 2021 - IPC F04F5/18 F04F5/46 

FIELD: fluidic instruments.

SUBSTANCE: invention relates to jet devices, namely to gas ejectors with supersonic nozzles and narrowing mixing chambers. In an ejector comprising a throat, a subsonic diffuser, a tapering mixing chamber, a common feed manifold equipped with a perforated separation wall, and 7 supersonic nozzles installed symmetrically relative to the ejector axis along the shell of the mixing chamber, the length of the throat is 4 calibers, and the supersonic nozzles are inclined so that the nozzle axes intersect the main axis at a distance of 5 calibers, while the nozzle inclination is made using gaskets for brackets installed on the wall of the mixing chamber.

EFFECT: increased compression ratio at a fixed ejection coefficient while reducing the weight and size characteristics of the ejector.
