  • Patent number: 5373811
    Abstract: The present invention is directed to an animal actuated drinking apparatus allowing animals to obtain liquid therefrom. The invention is directed to an apparatus, a kit, and a method of providing for an animal actuated drinking apparatus. The animal actuated drinking apparatus of the present invention includes a tubular body having a fluid passageway therethrough; an annular valve seat positioned within the fluid passageway, and an O-ring of resilient material seating against the annular valve seat. A valve actuator stem is adapted to seat against O-ring and in sealing engagement therewith. An elongated, generally cylindrical, elastomeric compression biasing sleeve of resilient material being in pressure contact with the valve actuator and maintaining the actuator in a neutral position. Displacement of the actuator stem from the neutral position causes fluid to flow through the apparatus. The replacement kits may be fitted with one or two piece actuators.
