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.

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.

Abstract: A sprinkler for irrigating large areas comprises a stationary bearing member (1) for the spray pipe (12) and also comprises a separate braking device (3). The braking device (3) comprises radial extensions (13), which are non-rotatably connected to the spray pipe (12).

To improve the braking action, interdigitating axial extensions may be connected to the radial extensions.
