Open the CIPO recordAbstract From the Canadian patent
An air flow amplifier of relatively high air flow amplification ratios in which a thin film of pressurized primary air flowing in a transverse direction is mechanically deflected to impinge on a generally frusto-conical surface tapering towards the throat of the amplifier. The deflecting action is produced by a deflection ring which is spaced inwardly from the amplifier's annular nozzle. The ring has an internal diameter substantially larger than the amplifier's throat so that secondary air entering through the ring may flow directly towards the frusto-conical surface to mix with the primary air flowing along that surface.
