ABSTRACT:
A valve mechanism for a livestock watering bowl. The valve mechanism is mounted in a water inlet line in the bowl and is adapted to be actuated by an animal to control the flow of water into the bowl. The valve mechanism includes a body provided with an inlet connected to the water line and having a central chamber connected through an inlet passage to the inlet. The inlet is adapted to be opened and closed by a valve member carried by a plunger that extends axially through the inlet passage and the central chamber and terminates in a button that projects outwardly from the opposite end of the body. The portion of the plunger located within the inlet passage has a non-circular cross section to provide a clearance between that portion of the plunger and the inlet passage, while the portion of the plunger located within the central chamber is formed with a laterally extending shoulder. When the button is pushed by an animal, the valve member will be moved to the open position enabling water to flow through the inlet passage to the central chamber where it is deflected and reduced in velocity by the shoulder and is discharged to the outlet. The valve mechanism provides a substantial volume of water flow without splashing or overflowing of water in the bowl.
