Abstract:
1. A spray head for use with pressurized water originating from a water source to produce a generally 360° spray pattern, comprising: a body having a proximate end, a distal end, and a sidewall connecting the proximate and distal ends, said sidewall defining a plurality of sidewall ports, said body further having a cavity; wherein the distal end of the body defines a distal port adapted to be coupled to the water source and wherein the proximate end of the body defines a proximate port; an interior wall disposed within the body and defining at least a portion of the cavity, said interior wall further defining a plurality of interior ports; wherein the body further defines a first channel and a plurality of secondary channels, the first channel being adapted to provide a first channel water flow path from the distal end of the body to the cavity, and each of the plurality of secondary channels being adapted to provide a second channel water flow path from one of the plurality of interior ports to one of the plurality of sidewall ports; a member disposed within the body and defining at least one swirl port, the at least one swirl port situated in the first channel water flow path for inducing a circumferential flow component to water in the cavity; wherein the at least one swirl port, the cavity and the proximate port are adapted to permit the pressurized water to flow from the at least one swirl port through the cavity through the proximate port and to disperse the pressurized water radially outward away from the body in the generally 360° spray pattern; wherein each secondary channel defines a pressure-reducing tortuous flow path to reduce the velocity of water flowing therethrough and is adapted to disperse water in a wedge-shaped spray pattern to an area close to the spray head relative to water dispersed from the proximate port; and wherein the dispersion of water through the proximate port and each of the sidewall ports is continuous and unobstructed when water is supplied from the water source.
