  • Patent number: 4109671
    Abstract: A nonfreezing, nonpolluting hydrant construction. The hydrant includes an above-ground discharge head, a main valve body disposed below frost line, and a stand pipe interconnecting the two. A flow tube is mounted inside the stand pipe. The upper end of the flow tube is connected to a hydrant opening and closing actuator which reciprocates the flow tube. The lower end of the flow tube carries an ejector assembly incorporating a venturi. In its lower position the ejector engages a seat to close off an inlet line. When the hydrant is shut off, water in the upper portion of the hydrant drains to the valve body and lower portion of the stand pipe below frost line. On subsequent opening of the hydrant, this water is ejected through the venturi. The hydrant also includes a float and check valve assembly to prevent filling of the stand pipe in the event the discharge line is blocked while the hydrant is open. A modified unit in which the hydrant mechanism is embodied in a drinking fountain is also disclosed.
