ABSTRACT:
A drinking water dispenser for animals for use in suspension-type water supply systems includes a pin received within a vertical bore in a housing and having a lower portion projecting downwardly through the bore, and an upper portion formed with an enlarged head, and overlying weight engageable with an upper portion of the pin, the enlarged head of the pin having a surface engageable with a surface of the housing around the bore. One or both of the latter surfaces are rounded such that the two surfaces define between them a valve which may be opened either by raising the pin or by tilting the pin. In addition, the weight is spaced from the upper portion of the enlarged head of the pin so as to be separated therefrom by a gap when the pin is not tilted or raised.
