Abstract (en)
[origin: US4403739A] A device for aerating a jet of water, particularly for the delivery spout of a hydraulic apparatus, with a mixing chamber, an air intake, a delivery orifice provided with nets for regularization of the jet, and a pulverization device comprising a first and a second element having each at least a ring series of openings of relatively large size, these two elements, when in the position of finer pulverization, being superimposed in such a way that the openings of the two elements register with each other along small portions adjacent to the edges, thus forming a plurality of restricted passages. Perferably, the opposite edges of each opening of one element form two narrow passages with the adjacent edges of two subsequent openings of the other element, thus producing slanting jets which meet the one another and thereby pulverize. The second element may be displaced, interchanged or omitted in order to obtain different working conditions.
