Abstract
Abstract A device for dispersing fluids into a gaseous environment which includes a hollow body mounted for rotational movement about an axis of rotation by a motor or the like, the hollow body having a plurality of discharge orifices spaced circumferentially about the axis shaped to disperse fluid under pressure communicated interiorly therewith outwardly thereof in a pattern which diverges outwardly with respect to a line of symmetry, the line of symmetry associated with each orifice being related to a line tangential to the axis of rotation intersecting the associated orifice by an angle of less than 46* measured in any direction therefrom whereby dispersion of a source of fluid communicated with the inlet of the hollow body is distributed through the orifice into the surrounding gaseous medium under the action of both the pressure energy and kinetic energy developed during the operation of the device.

Claim 1
Independent Claim
274 words
A device for dispersing fluids into a gaseous environment comprising a hollow body having an axis of rotation, said body having a plurality of discharge orifices spaced circumferentially about said axis, each of said orifices being shaped to disperse fluid under pressure communicated interiorly therewith outwardly thereof in a pattern which diverges outwardly with respect to a line of symmetry, each of said orifices being positioned so that said line of symmetry is related to a line tangential to the axis of rotation intersecting the associated orifice by an angle of less than 46* measured in any direction therefrom, said body having inlet means for communicating a fluid source to the interior of said body at a position adjacent the axis thereof, and interior surface means for confining the fluid communicated with said inlet means to a flow path outwardly from said position adjacent said axis to said discharge orifices, and power means operatively connected with said body for imparting a rotational movement to said body about its axis in a direction corresponding to the outward extent of said tangential lines while said inlet means is communicated with a fluid source so that such fluid will flow outwardly of said discharge orifices with the combined energy resulting from the pressure and flow velocity of the fluid source into said inlet means, the pressure and flow velocity imparted to the fluid entering said inlet means by centrifugal force during the outward movement thereof along said interior flow path and the component of tangential velocity imparted to the fluid as it discharges from the orifices by the component of movement of the orifices in that direction.
