Abstract
A water sprinkler is disclosed having a rotatable water driven nozzle member and a stationary spout for simultaneously discharging a twirling stream of water from the nozzle member and a pulsating stream from the spout. A chamber is provided within which a pulsating valve is rotatably mounted about its hollow stub shaft. The shaft is secured to the nozzle member for rotation therewith, and allows passage of water from a water inlet through the nozzle member. The stub shaft of the pulsating valve further has a laterally extending segmented plate for intermittently opening and closing the spout for allowing a pulsating stream of water to pass therethrough. The water sprinkler is further provided with one or more water outlets connectable to a hose or spray forming nozzle. A rotary valve is provided for selectively connecting the water inlet to a selected one of the chamber and water outlets. The outer housing of the water sprinkler is formed to simulate a colorful fire hydrant.
