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.

1. A spray head assembly comprising:a chamber having a fluid inlet and a fluid outlet with a velocity tube; a spray nozzle having a fluid inlet in fluid communication with the velocity tube, the spray nozzle having a plurality of outlet channels; a bypass channel providing fluid communication between the chamber and the fluid inlet of the spray nozzle downstream of the velocity tube; a bypass valve disposed in the bypass channel to control flow from the chamber through the bypass channel to the spray nozzle fluid inlet, wherein the bypass channel and bypass valve provide fluid to the spray nozzle at a velocity that is less than the velocity of fluid passing through the velocity tube.
