Title: Shower bath spray head
IPC: B05B1/12
Filed: 1982-06-26
Abstract: EP--66289 A The spray head for a shower bath is designed to produce different types of water spray. A device for mixing the water with air is incorporated in the shower head. The aerated water emerges from groups (16) of holes (11) which are arranged in two concentric circles in a disc (3). - A second disc (4) has groups of two types of holes (5 or 6). Both types are covered by a mesh (8), whilst one hole type (5) has an additional layer of mesh (7). By rotating the disc, one or other type of hole can be brought in line with the water flow to produce the required type of spray.

(22pp Dwg.No.1,2/9) - EP--66289 B Shower head for the selective production of different spray streams, each of which is formed by a plurality of individual streams, using a perforated disc (3) for the production of high-speed jets, a screen arrangement (7, 8) arranged behind it for the production of bubble-laden individual streams and a conversion means (4, 9, 10) for altering the characterstics of the spray, an individual screen arrangment being provided for each spray stream and screen arrangements differing from one another with respect to the number of individual screens (7, 8; 8) arranged therein, characterised in that holes (5, 6) are associated with the screen arrangements (7, 8), said holes having a height such that they each form one individual stream departing from the shower head, the holes (5) associated with the screen arrangements having the larger number of individual screens (7, 8) having a larger cross section than the holes (6) associated with the screen arrangements having the smaller number of individual screens (8). (Dwg.1/7)l USAB- US4733818 A The showerhead has an upstream disc with chambers for directing the water downstreamwardly. In the path of the jets from the chambers there is a screened-disc which is rotatable selectively by the user and which has a number of openings. By bringing the correct opening below the jets, the user may select one of several different types of streams. - One of the openings has two screens, one at the top and one at the bottom of the opening so that, at low water pressures, there is abundant aeration which provides a rich outgoing stream of water. For a normal aerated showerhead, there is a hole with just one screen. Similarly, there is a third hole without any screen and which will produce a spray when that hole is located below the chambers.
