  • Patent number: 4532954
    Abstract: A wall hydrant is described herein comprising a hollow tube having an inlet end and outlet end. The inlet end is adapted to be connected to a source of fluid under pressure and has a valve means adjacent its inlet end. The inlet valve means comprises a cylindrical body portion having an inward end terminating in an arcuate nose portion. A plurality of spaced apart tab elements extend outwardly from the body portion and bear against the inward surface of the hollow tube. A longitudinally extending groove is located on the outer surface of the body portion. A valve seat portion is provided in the inlet end of the tube. A valve control rod is connected to the valve means and extends through the opposite end of the hollow tube to permit remote control of the valve means and to selectively permit the valve means to slide inwardly to a closed position on said tabs, and outwardly to an open position. A drain valve is positioned on the rod and bears on a second valve seat portion when the valve means is open.
