Abstract (en)
[origin: EP3163093A1] An ejector for generating a vacuum comprises a drive nozzle (120) and a ring drive nozzle (140). The drive nozzle (120) is for generating a drive jet of air from a flow of compressed air and directing the drive jet of air into a first section expansion nozzle (130) in order to entrain air in a volume surrounding the drive jet of air into the jet flow to generate a vacuum across the first section. The ring drive nozzle (140) is for generating a drive ring of air from the flow of compressed air and directing the drive ring of air onto the jet flow and the entrained air, and into an inlet of a second section expansion nozzle (150).
