Abstract: A showerhead system for communicating a fluid supply, the system including a fixed fluid dispensing unit supported at a location, the fixed dispensing unit including a plurality of nozzles in fluid communication with the fluid supply. A removable fluid dispensing unit is releasably secured to a receptacle established within the fixed dispensing, the removable unit further including at least one additional nozzle. The fluid supply is adapted to be in selective communication with either or both the fixed and removable fluid dispensing units, such as through the provision of a fluid diverter element located at an inlet of the fixed unit and from which extends a conduit in separate communication with the removable unit.

Abstract: The showerhead engine assemblies provide different combinations and variations of continuous, deflected, pulsating sprays, and aeration spray patterns including those that are adjustable enabling wide variations in the degree of aeration of the water passing through the showerhead, enabling wide variation of the characteristics of the water spray patterns. The spray patterns include a nondeflected, nonpulsating spray pattern; a deflected nonpulsating spray pattern; a nondeflected, pulsating spray pattern; and a deflected, pulsating spray pattern, while enabling the engine assembly to be self-cleaning. For pulsating spray modes, the showerhead engine assembly includes but five plastic parts and an O-ring seal; the parts being a stator, a spinner, an engager, a pressure plate, and a faceplate, openings beings disposed in the pressure plate and faceplate to enable fluid flow therefrom. Deflecting surfaces on the faceplate enable a variety of different flow patterns.
