Patent number: 6719218Abstract: A shower head has a housing with a water inlet and a control valve which connects to the housing inlet and has a plurality of water outlets. The control valve regulates the flow of water to a plurality of circumferentially arranged spray openings and to a nozzle which is located within the periphery of the spray openings. The nozzle has the ability to turn or spin, thus providing a soft spray which may be independent of or concurrent with the discharge of water from the spray openings. The nozzle may also wobble, which movement may be described as nutational, or the slow movement of the axis of the nozzle about another axis. Wobbling movement provides a somewhat more concentrated spray than that provided when the nozzle only spins. The shower head further has an auxiliary port which may be utilized with other spray devices such as fixed sprays or hand-held shower heads.Type: GrantFiled: June 25, 2001Date of Patent: April 13, 2004Assignee: Moen IncorporatedInventors: Lonnie F. Cool, Mark S. Kacik, Yaakov Korb, Richard A. Parso, Stephen J. Zaborszki
