Abstract: An animal watering valve that includes a housing having an internal bore having an upstream inlet and a downstream outlet. The housing includes a downstream guard and an upstream cap. The valve is actuated by deflecting a valve stem, located in the bore and accessible by the animal, to open a valve within the housing. The valve may be located in a valve cartridge retainable in the housing in a snap-fit manner. A bite-resistant shield cooperates with the valve stem to act as a barrier that prevents an animal from forcing materials between the valve stem and the guard and lodging the valve stem in its deflected or actuated position.

Abstract: An automatic animal watering system has a manifold for transporting drinking water, a controlled volume dispenser in the manifold for receiving a volume of drinking water, an inlet valve, and an outlet valve. A plurality of drinking valve assemblies is provided in fluid communication with the manifold between the inlet and outlet valves. A fluid sensor, capable of responding to changes in one or both of the water volume and pressure, is provided in the manifold between the inlet and outlet valves. The volume of drinking water available to the drinking valve assemblies can be regulated as a function of time to limit maximum potential leakage. The system also includes a controller receiving signals from the fluid sensor and generating a response to changes in the monitored water volume or pressure, thereby limiting potential water leakage in the system.

Abstract: A fluid absorbent assembly includes a fluid absorbent material located in an animal cage or in a liner inserted into the cage. The fluid absorbent material may comprise or be combined with a material that absorbs or neutralizes noxious vapors. A fluid permeable animal support structure may be located over the fluid absorbent material. The fluid absorbent material, which may be contained in a pad, may be contained in a housing that also forms the animal support structure. In the event of a drinking valve leak or other fluid leak within the cage, the fluid absorbent material expands and raises any animals located within the cage.
