Abstract
A sprinkler includes a housing having a water inlet and a water outlet. A plug is slidably secured in the housing and may be moved toward and away from the water outlet for adjusting outlet water quantity. A block is rotatably supported in the housing and has a helical groove for engaging with the plug and for moving the plug forward and rearward relative to the water outlet. The water outlet quantity may thus be adjusted for allowing much water to sprinkle the farther area and for allowing less water to sprinkle the closer area to the sprinkler.
