Abstract
A water dispenser for feeding small animals comprising a casing supplied with water under positive pressure and having an outlet at its downstream part, a valve for controlling water feed disposed in the outlet, and a water feed tube. The valve comprises an elastic valve seat member having an annular disk portion constituting the valve seat and a cylindrical portion formed coaxially and integrally with the disk portion and a poppet valve normally closed against the valve seat and fixed to the upstream end of the feed tube, which, upon being nudged and moved at its downstream end by a small animal, opens the poppet valve to permit water from a supply to enter the cylindrical portion of the valve and then into the feed tube. A flow control rod with transverse comb-cut grooves is inserted in the feed tube to prevent excessive rushing of water therethrough.
