Sprinkler with top-side remotely vented pressure regulator |
摘要 |
An irrigation sprinkler includes a riser and a nozzle rotatably mounted at an upper end of the riser. A gear train reduction is mounted in the riser and a turbine is coupled to the gear train reduction for rotation by water entering a lower end of the riser. A gear driven coupling mechanism mounted in the riser couples the gear train reduction and the nozzle. A pressure regulator is mounted in the riser and is adjustable from a top-side of the sprinkler. |

1. An irrigation sprinkler, comprising:
a riser; a nozzle turret rotatably mounted at an upper end of the riser; a gear train reduction mounted in the riser; a turbine coupled to the gear train reduction and rotatable by water entering a lower end of the riser; a gear driven coupling mechanism mounted in the riser and coupling the gear train reduction and the nozzle turret; and a pressure regulator having a valve portion mounted in the riser adjacent a passage that provides a water flow path to the nozzle, the pressure regulator including a valve body movable relative to at least one water flow port to increasingly obstruct the at least one water flow port, a spring connected to bias the valve body to affect a pressure of the water at an entrance of a nozzle in the nozzle turret, and an air flow path separated from the water flow path that vents the valve portion of the pressure regulator to ambient air pressure; wherein the spring that biases the valve body is mounted in the nozzle turret. |
