Abstract
A watering assembly for controllably dispensing water from a supply source into a drinking cup mounted on an animal watering apparatus and formed to prevent the accumulation of particulate matter on the top of the valve and induce and enhance agitating flow patterns created by water being discharged from the watering assembly. The watering assembly has a valve which is at least partially disposed within the cup and has a regulating portion which is activated by an animal forceably contacting the valve. Once activated, water flows from the valve and is directed downwardly into the cup by a deflector member whereupon the water flows over a flow directing portion of the valve which enhances the agitating flow patterns to thoroughly mix the water with any sedimentation which may have accumulated in the cup. Enhanced flow patterns created by the flow directing portion of the valve thoroughly mix the water in the cup preventing sedimentation build-up in blind areas or still areas. The flow directing portion is formed on an upper portion of the valve which is disposed within a container and has a generally conical shaped dome thus preventing particulate matter from accumulating on the upp…
