32 are open for creating first and second flows of water a and b respectively due to the geometry of the channel 122 the first and second flows a and b are correspondingly angled slightly downward an opening 128 in a lower side of the channel 122 provides for a third flow of water c in one particular application water dispersed from the nozzle 32 is regulated to a rate of approximately 2 5 gallons per minute in this application the flow of water is allocated approximately as follows a 35 b 35 and c 30 as diagrammatically shown in the cross sectional view of fig4 the flows a b and c from the nozzle 32 create a flush pattern for full coverage of the bowl 24 the nozzle 32 pressurizes the water and the rim 26 provides protection against splashing the water flows a and b define a symmetrical pattern and converge at an imaginary line x that passes through the nozzle and the front of the bowl 24 directly opposite the nozzle 32 the increasing horizontal width of the ledge 27 and the increasing slope of the ledge 27 as the ledge continues from adjacent the generally vertical surface 29 causes the water flows a and b to gradually cascade downward from opposing directions as they progress toward the front of the bowl 24 in this manner water from flow a and flow b is under enough pressure even under lower pressure conditions to provide complete wetting of the bowl 24 with particular reference to fig1 and.
