Abstract:
1. An animal drinker, comprising: a base tray defined by an exterior drinking trough and an interior fluid reservoir and including a connecting passageway for maintaining a fluid at a fluid level that is the same in each of the exterior drinking trough and the interior fluid reservoir; an upper reservoir for storing fluid positioned above the interior fluid reservoir and having an outlet positioned at a bottom of the upper reservoir; a buoyant float pan positioned in the interior fluid reservoir of the base tray; and a cylindrical float stop positioned between the float pan and the outlet of the upper reservoir to selectively stop a flow of the fluid from the upper reservoir to the interior fluid reservoir, wherein the cylindrical float stop defines an interior channel having a void for holding air and the cylindrical float stop is capped at each end by a flat stop for holding air in the void to give the float stop a substantially flat top surface and a substantially flat bottom surface, and the cylindrical float stop has a plurality of ribs spaced around the cylindrical float stop that each extend linearly and substantially a length of the cylindrical float stop between the substantially flat top surface and the substantially flat bottom surface.
