Water distribution device

Image Number 5 for United States Patent #5366618.

A water distributor for distributing a flow of water to at least one of a plurality of output ports. The particular output port(s) chosen varies as a function of time and depends on the position of a motor driven rotor within the distributor. In another embodiment of the invention the distributor distributes water to at least one of a plurality of nozzles and draws water through at least one of the same plurality of nozzles. Other ones of the plurality of nozzles are neither outputting nor drawing in water. The function of a particular nozzle is dependent on the position of a rotor within the distributor. The rotor is motor driven whereby the function of a particular nozzle changes as a function of time as the rotor rotates. Each distributor of the invention is particularly adaptable for coupling to a fresh or salt-water aquarium to provide the aquarium with time varying currents and eddies. The distributors thus provide a varying flow of water to an aquarium to disperse pollutants and contaminants and provide oxygen to the water.
