Abstract

Improvements in mixed ejector apparatus, of the type comprising in succession in the general direction of fluid flow, an inlet section defined in part by a secondary fluid flow inlet opening, and by a curved inlet surface, a section of neck and a diffuser section defined in part by a diverging wall surface and by an outlet opening, characterized in that each apparatus is provided in combination with; central means and injectors with a discharge nozzle positioned in the central region of the inlet surface of the secondary flow fluid of the inlet section generally above the diffuser section, and oriented to inject the primary flow fluid passing through of the neck section of the ejector and the diffuser section of the ejector; Perimeter injector means positioned in the inlet section and having a COANDA slot opening in said inlet zone of secondary flow fluid of the inlet section and adjacent to the curved inlet surface to inject primary flow fluid into the central region of the inlet area and through and through the ejector neck section and said ejector diffuser section; and fluid conduit control means that conducts the high energy primary flow fluid to the perimeter injector means for injection by said discharge nozzle and slot opening COANDA.
