Abstract

The aspirating liquid flow tube in the form of a dual vertical concentric tube assembly or a single vertical tube with a vertical transverse internal wall for a vacuum cleaner dump bucket is closed at its upper end, and is provided with a single axial opening or opposed radial nozzles for discharging dirty liquid induced by the vacuum promoted air stream against 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.
