Abstract
The aspirating liquid flow tube of a dual concentric tube assembly for a vacuum cleaner dump bucket is closed at its upper end, and is provided with opposed radial nozzles for discharging dirty liquid induced by the vacuum promoted air stream tangentially against the curved sidewall of the dump bucket dome above the ring baffle to facilitate separation of the liquid from the air stream and distribute the liquid about the full circumference of the dome sidewall prior to contact with the ring baffle to increase dump bucket capacity without introduction of liquid into the hollow riser tube leading to the vacuum source.
