FIELD: jet equipment.
SUBSTANCE: invention relates to jet engineering, particularly, to gas ejectors. Ejector comprises an underwater channel, a mixing chamber, a vacuum chamber with a slit connecting it with the gas bleed zone, an outlet diffuser and a cavity and a resonator tube installed between the underwater channel and the mixing chamber, which together form a resonator.
EFFECT: invention increases the ejection ratio by 2–2,5 times.
