Switching current water director (SCWD) for aquariums










Image Number 4 for United States Patent #6796273.

The present invention relates to a water director for distributing a surge or flow of water to one or more of a plurality of output ports, which can vary in shape, size, and number, typically for use in marine and fresh water aquariums. Water pumped through a conduit into the hermetically sealed Switching Current Water Director (SCWD), powers an internally mounted gear driven fluid motor, which turns a rotational valve, alternately opening and closing a plurality of water outlet ports. When mounted externally to an aquarium, proper placement of output nozzles, which are connected to a water conduit attached to the various SCWD outlet ports, provides the desired opposing, or switching back and fourth currents. Depending on the inlet and outlet port configuration, the SCWD can be adapted to suit many applications.
