The actuation mechanism is comprised of a pushbutton, a guiding member, a limiting sleeve and a shell. The pushbutton, guiding member and limiting sleeve are housed in the shell. The pushbutton is attached to the guide member that selectively slides in the limiting sleeve. A connecting rod attached to the guiding member interfaces with the valve in the sprinkler and actuates the flow of water.

Registration elements are provided to ensure the proper alignment between the members of the apparatus. Correspondingly, indicia located at upper and lower external surfaces of the assembled apparatus reduce or eliminate the need to disassemble the apparatus or intermittently test the water spray pattern to ensure proper installation of the apparatus. Preferred methods for assembling the apparatus, for directing the outflow of water, and for aligning the members of the apparatus are disclosed.

Abstract: The present invention provides a spray head assembly with a moving spray nozzle that delivers fluid in a substantially uniform spray distribution. The movement of the spray nozzle is a wobbling motion, preferably combined with some rotational motion. The wobbling motion is generated by disposing a wobble inducing member or wobble turbine in the path of the fluid supply. The water flowing over the wobble turbine causes the turbine to wobble. The wobbling turbine then causes the spray housing and nozzle to wobble. The spray pattern produced by the wobbling spray housing changes more or less rapidly so that fluid droplets or streams are directed along arcuate paths rather than at a single point. This type of spray distribution pattern is gentler than many stationary patterns and the unique design of the wobble inducing member does not include complex mechanical parts or significant flow restrictions.
