Abstract: A shower head assembly includes an outer housing, an inner housing, a catch cap, and an impeller. Thus, the catch cap catches the water flow and introduces the water flow through the water inlet hole into the air chamber so as to reduce the water flow rate, thereby achieving the purpose of saving water. In addition, the water flow is ejected outward in a radiating manner by rotation of the impeller, thereby providing a massaging effect to the user.

Abstract: An irrigation sprinkler with two viscous brakes. The viscous brakes work in conjunction with each other to maintain a low RPM and also to rotate a water stream diffuser. The water stream is first directed toward a deflector that offsets the stream and angles it toward the area to be watered. The offset stream applies a torsional force on the deflector causing it to rotate. The stream is then interrupted intermittently by the diffuser that is rotating at a different RPM. The end result is a sprinkler that rotates slowly and breaks up the stream of water intermittently to create an even pattern of water on the area being sprinkled without using mechanical parts, such as ratchets or gearing. This is desirable for smooth operation and less chance of the operation being interrupted from contamination by dirt, insects, debris, etc. Also, a more random diffusion of the water is obtained.

Abstract: The present invention provides an apparatus with a wobble turbine that delivers fluid in a substantially uniform spray distribution. The movement of the wobble turbine 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 has outlet channels disposed therein that distribute the water. The spray pattern produced by the apparatus 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.
