LIQUID-GAS EJECTOR Russian patent published in 2017 - IPC F04F5/04 F04F5/46 

FIELD: machine engineering.

SUBSTANCE: ejector contains a distribution chamber with nozzles, a receiving chamber, mixing chambers and a discharge chamber. Each mixing chamber is mounted coaxially with respect to its nozzle. The nozzle consists of an outer cylindrical shell in which a bushing of antifriction composite material is mounted, the buching hole has a variable cross section that narrows down the flow direction, and annular grooves located along helical path are arranged on the inner surface. In addition, the mixing chamber consists of an outer cylindrical shell, into which a bushing of antifriction composite material is mounted, the bushing hole has constant cross-section.

EFFECT: increasing the ejector efficiency while reducing the device weight and simplifying the manufacturing process.
