A garden sprinkler has an input base, an output member rotatably installed at the top of the input base, and a rotating member capable of driving the output member. The output Both sides of the output member are respectively equipped with a first outlet and a second outlet. The first outlet is equipped with a first sprinkler, and the second outlet is equipped with a second sprinkler and an adjusting sleeve. The second sprinkler is a side outlet and is screwed with the adjusting sleeve. The second sprinkler can be adjusted by the adjusting sleeve, which improves the convenience of sprinkling operation without multiple sprinkler heads.

There is provided a turf cup assembly that attaches to a buried pop-up type sprinkler to blend a top of sprinkler both cosmetically and functionally with turf surrounding the sprinkler. The turf cup assembly includes a turf cup and a sleeve. The turf cup mounts to a riser of the pop-up type sprinkler. The turf cup contains soil and root structure of turf. The sleeve surrounds the turf cup and attaches to a top of a housing of a pop-up sprinkler. The sleeve can be at or slightly below grade, and the cup extends out of the sleeve during an irrigation cycle and retracts into the sleeve at the end of the irrigation cycle.

Rotational speed of a spray arm is regulated based on centrifugal force and a liquid jet to create a variable angle corner spray nozzle. The regulator includes a weight on a pivot and a fluid jet, the weight having a curved surface to produce a variable angle corner spray nozzle depending on the weight angle. Centrifugal force created during rotation pushes the weight outward, which increases as the spray arm rotation speed increases. The liquid jet is located out from a pivot point and tends to push the weight inward. The pushing force of the liquid jet is maximum when the weight is most inward and minimum when the weight is most outward. The regulator stabilizes the arm speed at a specific speed independent from center pivot friction and the spray arm nozzle's orientation tolerance. Speed stabilizes when centrifugal force on the weight is equal to the pushing force of the fluid jet.

An exterior fire suppressing system includes a flagpole that has a bottom end and an upper end. The flagpole has a height above a ground surface that is greater than 10.0 feet when the bottom end of the flagpole is anchored in the ground surface. A halyard is mounted on the flagpole and engages a flag to raise and lower the flag on the pole. The flagpole has a conduit therein for transporting a fluid. The conduit has an inlet positioned adjacent to the bottom end and an outlet adjacent to the upper end. A water sprinkler is mounted on the flagpole and is fluidly coupled to the outlet. The water sprinkler is rotatable and disperses water in an arcuate pattern extending outwardly from the flagpole wherein the flagpole defines an axis of the arcuate pattern of dispersed water. A hose connector is fluidly mounted to the inlet.

An irrigation sprinkler has a vertical axis (A) and is configured to emit a liquid jet. The sprinkler includes a base and a head operatively connected to the. A reciprocal element rotatably mounted to the head is configured to undergo reciprocal motion about the vertical axis (A), in response to being impacted with the liquid jet from a nozzle belonging to the head. The reciprocal element has a diffuser arm which carries a plurality of integrally formed, spaced apart diffuser posts which are configured to be hit by, and diffuse the liquid jet during the reciprocal motion.
