Abstract: A flow controller for connection between a shower supply pipe and a shower head is disclosed which provides an intense, highly atomized spray to the shower head while reducing the amount of water used, as well as the amount of energy necessary to heat the water. The flow controller contains a controlling shaft which directs two high velocity streams of water against a wall in the flow controller to atomize the water. The controlling shaft, which is movable to provide a continuously variable control over the amount of water flowing through the flow controller, is rotated by a convenient horseshoe-shaped handle to allow the user to easily change the amount of water supplied to the shower head.
