Abstract

A shower head having a plurality of spray modes and unique controls to allow the selection of the desired mode. The shower head includes several unique features to allow the inclusion of several different spray modes, such as wide spray, medium spray, center spray, champagne spray, high speed pulsating spray, low speed pulsating spray, and mist. A waterfall mode can be implemented. The shower head includes a flow control valve that controls the pressure of the water flow, and acts to divert water to a mode selector or to a separate spray mode, such as the mist mode. The flow control valve diverts water between the mode selector and the separate spray mode. It also allows a combination of the modes controlled by the mode selector and the separate spray mode. The shower head also includes a mode selector. The mode selector transfers or routes fluids from the flow control valve to any number of individual or a combination of flow spray mode outlets.
