Description:
FIELD OF THE INVENTION 
     This invention concerns showers for the delivery of differentiated jets of water. 
     BACKGROUND OF THE INVENTION 
     Already available on the market are those showers with a head housing concentric elements assembled as a unit and which form a combination of one, two or more types of passage for the delivery of the same number of different jets of water, and where at least one of the elements can be rotated by hand to distribute the incoming water through at least one feed hole and selectively through each type of passage depending on the shape of the required jet of water. 
     Such showers are usually pre-set for the delivery of different types of jets of water, such as, fine, delicate (soft), pulsating or massaging, etc, and the methods used to move from one type of jet to another are known. 
     SUMMARY AND OBJECTS OF THE INVENTION 
     The foremost aim of this invention is to produce and supply a shower capable of delivering atomised jets of water besides the other common types of jets of water. 
     Another aim of this invention is to propose a shower with incorporated injector-diffuser units having a particular configuration and combination to generate and deliver atomised water through a crown of nozzles with the advantage of having water finely subdivided for various uses that is not possible to achieve with the more traditional showers. 
     The aims of the present invention are accomplished with the shower having a housing defining an opening for receiving liquid, such as water. The plurality of different types of nozzles are in the housing, where one of the types of nozzles are atomizer type nozzles. The atomizer type nozzles are ranged in a crown pattern in the housing. A control element is also positioned in the housing and selectively communicates passages between the opening in the housing and the plurality of different types of nozzles.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The shower shown is composed of a body a housing  20  having a longitudinal duct or opening  21  connected to a water inlet pipe—not indicated—having an outlet  22  towards well known elements not requiring definitions, whose purpose is to control the water delivery according to the different jets. 
     In the example shown, such elements include a multiple-way conveyor-distributor  23  equipped with a control knob  24  capable of selectively deviating the water from the incoming duct  22  to a first series of external nozzles  25  for the delivery of fine jets of water, to a diffuser with nozzles  26  for delivery of pulsating or massaging jets of water, and to a crown of atomizer nozzles  27  for the delivery of the water in future different shapes or forms. 
     According to this Invention this crown of nozzles  27  is aimed at delivering for the most part atomised water. 
     Such atomizer nozzles  27  have the form of teats in a ring-shaped diffuser  28 , preferably a rubber one, together with the first series of nozzles  25 , in the form of teats—FIGS. 5-7. 
     The ring shaped diffuser  28  is held and coupled with a rigid flange  29  presenting a series of holes  30  for the first order of nozzles  25  and a second series of holes or atomizer nozzles holes  31  for the crown of atomizer nozzles  27 , FIGS. 2-4. 
     Another diffuser with nozzles  26  for the massaging jets of water is positioned in the centre of the flange  29 —FIG.  1 —and receives water from a analogous duct  26  controlled by the distributor. 
     A ring  32  with water ducts, coinciding with the first order of nozzles  25  is located around the flange  29 . The water reaches these nozzles by flowing through a duct  33  governed by the distributor  23 . 
     A rigid injector ring  34 , which holds several atomizer injectors  35  has been inserted in the ring-shaped diffuser  28 , each positioned in correspondence with one of the nozzles In the crown of nozzles  27 . The injector ring  34 , the diffuser ring  28 , the flange  29  and the distributor  23  are substantially concentric. 
     The injectors  35  receive water through the holes or injector passages  36  that can be opened and closed as often as one wishes, governed by the distributor  23  when the form of the jet of water to be delivered is selected. 
     Each injector  35  is made up principally of a cylindrical element projecting from the injector ring  34  towards the inner chamber of its corresponding nozzle  27 . The projecting element—FIGS.  8 - 12 —presents longitudinal lateral channels  37 , each of them in communication with a central chamber  38  provided at the base of the element and open towards the atomiser nozzle  27 . More precisely, each longitudinal lateral channel  37  is connected to this central chamber through a non-radial passage  39 , but orientated at a tangent to the cavity itself—FIG.  11 —. 
     In this way, when the distributor  23  is in the position to send water to the injectors  35 , the water is obliged to pass through the lateral channels  37  of each injector and compelled to enter its lower central chamber  38  through the tangential passages  39 . Thanks to the location of these passages water will whirl into the chamber  39  increasing its speed and pressure and creating, however, the conditions to deliver the water in a fine atomised form from the corresponding nozzles  27 . The overall effect of the atomised water Is particularly appreciated and useful for various uses in the care of hair and skin. 
     While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
