  • Device for controlled discharge of liquid to animals
    Patent number: 4633816
    Abstract: A drinking valve (40) for supplying animals with water. This valve has an actuating member (46) accessible to the animal which when actuated opens a flow path for the liquid through the drinking valve (40). In the non-actuated position the flow path through the drinking valve (40) is completely closed and in the position of maximum actuation the flow path is strongly restricted or completely closed. In the intermediary position the drinking valve (40) yields the amount of water which the flow path is intended to produce. The actuating member (46) is connected to main closing valve (47, 49) which in turn actuates a secondary restricting or closing valve (53, 54).
