Abstract
Improvements in sprinkler systems having fluid under pressure flowing therethrough and a sprinkler head with a pop-up nozzle actuated by fluid pressure. An impeller is actuated by the fluid flow to rotate the nozzle and thus rotate the spray of fluid therefrom. A transmission is disposed between the impeller and the nozzle for transmitting rotation of the impeller to the nozzle. The transmission is sealed off from the fluid passing through the system by a resilient expandable diaphragm at one end. A fluid pressure responsive seal is provided in the system in sealing engagement with the nozzle. The sealed-off portion of the transmission is completely filled with a lubricating medium which is free to selectively contract or expand against the diaphragm in response to varying ambient conditions encountered by the sprinkler head. The nozzle may also include means for varying the pattern of the sprayed fluid and may be comprised of molded plastic components which may be assembled together.
