Patent ID: 7174911

Claim:
A fire hydrant, comprising: a. a barrel adapted to communicate at least indirectly with a water conduit, the barrel comprising breakaway structure; b. a nozzle extending from the barrel and communicating with the barrel; c. a hydrant valve adapted to controllably restrict communication between the barrel and the water conduit; d. a valve actuator adapted to allow actuation of the hydrant valve, said actuator comprising an actuator rod; e. a cap structure adapted to at least close off the end of the barrel not in communication with the water conduit; and f. a second valve adapted to open when the hydrant valve is opened, the second valve comprising: (i) a seat; (ii) a restriction member adapted to cooperate with the seat; and (iii) biasing structure adapted to bias the restriction member against the seat so that water from the conduit flows through the nozzle only when the hydrant valve is at least partially open and the nozzle is at least partially open.
