Abstract
An oscillating spray device comprising an oscillation chamber. A power nozzle for projecting a jet of liquid under pressure into the oscillation chamber in a given direction. A reversing member in the chamber has a reversing wall for reversing the direction of flow of the fluid jet in a direction 180° opposite the given direction. A system of vortices is formed thereby for alternately passing fluid to one side or the other of the reversing member. A pair of passages, one on each side of the reversing member, convey alternate pulses of fluid through the passageways in the given direction past the reversing member to an outlet to ambient, and an island barrier positioned in the outlet to ambient and forming two separate passageways to the outlet and a third passageway between the reversing member and the island barrier. The spray characteristics can be adjusted by changing the spacing between the reversing member and island barrier.
