Animal drinker

摘要

An animal drinker includes a base tray that is defined by an exterior drinking trough connected to an interior fluid reservoir by a passageway. The trough and the interior fluid reservoir are maintained at a consistent fluid level. An upper reservoir stores fluid above the interior reservoir and is in fluid communication therewith by an outlet positioned at the bottom. A buoyant float pan is positioned in the interior fluid reservoir of the base tray. A float stop is positioned between the float pan and the outlet of the upper reservoir to stop the flow of fluid from the upper reservoir to the interior fluid reservoir at a predetermined level.

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.
