EJECTOR Russian patent published in 2009 - IPC F04F5/30 

FIELD: machine building.

SUBSTANCE: ejector serves to displace low-pressure medium flow by high-pressure medium flow. Ejector comprises annular high-pressure medium nozzle 1, two concentric annular low-pressure flow nozzles 2 and 3, annular mixing chamber 4 and diffuser 5 formed by outer shell 6 and central body 7. Low-pressure flow is fed via pylons 8 to inner annular nozzle 3, pylons 8 connecting shell 6 and central body 7. Inner wall of high-pressure flow nozzle 1 is furnished with cylindrical shell 9 extending beyond outer wall 10 of high-pressure flow nozzle. Cylindrical shell 9 is arranged to displace axially relative to the edge of high-pressure flow nozzle conical outer wall.

EFFECT: creation of required parametres, ie temperature, concentration and flow rate, at diffuser edge.
