ABSTRACT:
A yard hydrant includes an improved valve assembly connecting the hydrant standpipe at a point below the frost line to a source of water under pressure. A hollow and generally cylindrical housing of such assembly is provided with a bore concentrically reduced relative to the diameter of the housing and having an upper plane spaced inwardly from the upper end of the housing to receive a rod mounted and handle operated valve. The bore terminates at its lower end in a valve seat defining a further concentrically reduced access opening to the water supply. In spaced concentric relationship about the bore are a plurality of water passageways each in communication with said bore and each extending from the upper plane thereof for communication with the standpipe to a point spaced above the valve seat so that the bore is full circle only intermediate the valve seat and the lower limits of the passageways. A drain hole is provided through the housing to the bore near the upper plane thereof. The seated valve shuts off the water supply and exposes the drain hole for water drainage to the surrounding ground from the standpipe and in the opening of the valve, water cannot flow to the standpipe until the valve has not only moved off of the valve seat but has moved beyond the full circle bore area to expose the lower end of the water passageways to communication with the source of water and at which time, the valve has closed the drain hole to prevent escape of incoming water at that point so that all of such water flows directly to the standpipe and nozzle. The design of the housing makes possible the use of plastic materials for economy in manufacture and efficiency in operation.
