Abstract
A fluid mixer and distribution device which comprises an oscillation/mixing chamber having an upstream end, a downstream end, top and bottom walls, sidewalls which diverge from the upstream end and then converge towards the downstream end. A power nozzle, adapted to be coupled to a source of liquid under pressure, issues a main jet of carrier fluid (a liquid, for example) into the upstream end of the oscillation/mixing chamber. The oscillation/mixing chamber has a pair of control ports symmetrically contiguous to the side of the main jet of liquid, and an exit aperture at the downstream end of the oscillation/mixing chamber for the egress of the mixed fluids from the oscillation/mixing chamber to ambient or a point of utilization. One or more sources of fluent materials connected to the control ports, whereby any vacuum caused by the main jet of liquid at the control ports entrains the fluent material for mixing with the carrier jet of liquid in the oscillation/mixing chamber to form a mixture for spraying to ambient through the exit aperture or to a utilization device.
