Showerhead with means for selecting various forms of output streams

In a device for producing bubbly streams over a range of water pressures:

• means for receiving water from a source and producing an output comprising jets of water,
• first means which when in the path of said jets breaks up said jets, offers resistance thereto, and mixes the resulting water with air to produce a bubbly jet of a first cross-section when the water pressure is in the higher part of said range,
• second means which when in the path of said jets breaks up said jets, offers resistance thereto in a lesser amount than that offered by said first means, and mixes the resulting water with air to produce a bubbly jet of a second cross-section, that is smaller than said first cross-section, when the water pressure is in the lower part of said range, and
• means operable for selectively causing said jets to either impinge only on said first means or only on said second means,
• said second means defining a passageway having said one screen across said passageway,
• said passageway tapering to thus narrow the same until its size substantially equals said second cross-section.

In a device for producing bubbly streams over a range of water pressures,

• jet producing means for connection to a source of water to produce at least one jet of water,
• control means having at least a high pressure setting and a low pressure setting,
• said control means, when in said high pressure setting, comprising first mixing means to break up the water of said jets and mix that water with air to form a bubbly stream of a first cross-section when the water pressure from said source is in the higher end of said range,
• said control means, when in said low pressure setting, comprising second mixing means, having lesser mixing capability than the mixing means involved in said high pressure setting, for providing sufficient mixing of the water from said jet forming means to break up the flow of that water and mix that water with air to form a bubbly stream of a second cross-section, smaller than said first cross-section, when the water pressure from said source is in the lower end of said range.

• each said mixing means comprising screen means,
• said control means including a passageway, when in said low pressure setting, that includes at least a part of said screen means, said passageway narrowing, downstream of said screen means, to said second cross-section.
