    摘要： A yard hydrant wherein no separate operating handle component is used or required and the operation of a valve assembly is accomplished by a movable spout head. A vertically disposed flow pipe disposed within a standpipe has a valve means at its lower end and is secured at its upper end to the hydrant head. Water under pressure reaching the valve will normally elevate the valve to closed position with the flow pipe and hydrant head being elevated accordingly. The valve means is either full open or full closed and is opened by depressing the hydrant head to correspondingly depress the flow pipe and open the valve. Means are provided to releasably lock the hydrant head and valve in depressed or full on position. Upon release of the head from depressed position, water pressure on the valve automatically elevates it to closed position. An adjustment means in the head relative to the top of the flow pipe is provided for regulating the volume of flow, if desired.
