  • Patent number: 5967417
    Abstract: A shower head, for example, a hand shower contains in its interior a means with which the flow of the water leaving the shower head through a jet orifice can be modulated relatively slowly. The means for modulating the flow of water may be powered, more particularly, by a turbine wheel arranged in the interior of the shower head. When two arrays of jet orifices are provided for producing two different types of jet the means may be used for automatic changeover between the two types of jet. The invention provides a shower with which the user is showered by all types of jet possible with the aid of the shower without requiring him to make a change by hand.
