Abstract: A sprinkler head including an adjustable valve with a valve opening and a movable valve means. The valve means includes a gate means movable into and out of the valve opening. The gate means and valve opening form a valve port to control fluid flow at relatively low fluid flow rates. The valve port includes a port perimeter and cross sectional port area in a plane lying generally perpendicular to the flow of fluid. The valve port is varied in size while maintaining a continuous port perimeter with a generally wide cross sectional port area.

Abstract: An automatic reset reversing mechanism that resets a sprinkler to its preset cycling path or arc after it is moved to a position outside of the preset cycling arc. The automatic reset reversing mechanism utilizes a single clutch tooth on a dog drum that supports the reversing dogs. The reversing dogs are adjustable on the dog drum into any desired angular position in order to preset the arc of movement of the cycling sprinkler nozzle. The base of the sprinkler includes a notch that mates with the single clutch tooth during normal reversing movement of the cycling sprinkler nozzle. The dog drum is also movable upwardly to remove the single clutch tooth from the mating notch when the sprinkler nozzle is moved forceably outside of the preset cycling arc. Further movement of the sprinkler nozzle will replace the clutch tooth in the mating notch to re-establish the original preset sprinkler nozzle cycling arc.

Abstract translation: 一种自动复位反转机构，可在将喷头移动到预设循环弧之外的位置时将喷头重置为其预设循环路径或弧。 自动复位反转机构使用支撑反转狗的狗鼓上的单个离合器齿。 反转狗可以在狗滚筒上调节到任何期望的角度位置，以便预设循环喷洒喷嘴的运动弧。 洒水喷头的底座包括一个与单个离合器齿匹配的凹口，在循环喷洒喷嘴的正常反向运动过程中。 当喷头喷射器可靠地移动到预设的循环弧线之外时，狗滚筒也可以向上移动以从配合凹口去除单个离合器齿。 洒水喷嘴的进一步运动将取代配合凹口中的离合器齿，以重新建立原来的预设喷洒喷嘴循环弧。
