Definitions

  • the present invention relates to an aerating device for a water jet, comprising a water spraying device, an air intake, a mixing chamber and a flow orifice provided with means for regulating the jet.
  • Such aerators are widely used especially for spouts of sinks, sinks and bathtubs, to obtain a regular spray with little tendency to produce spurts, as well as to reduce the noise of the tap.
  • these devices pose various problems, above all by the fact that effective spraying is generally obtained by passing the jet through numerous very small holes which are located opposite walls which, struck by thin partial jets, spray them.
  • the production of very small holes does not lend itself to mass production, and on the other hand it is not possible to increase the diameter of the holes without compromising either the effectiveness of the spraying or the silence of the device.
  • the presence of very small holes crossed by the water flow quickly leads to their clogging and therefore to the need to replace the device, being practically not possible to clean effectively the engorged holes.
  • the object of the invention is to provide an aerator device of simple and economical manufacture, which is free from the drawbacks of known aerators or which presents them in reduced measure and, in particular, which does not require the execution of very small holes, while ensuring effective spraying and aeration of the jet even when a sphere or the like is not used for stabilization.
  • An auxiliary object of the invention is that of providing an aerating device which can be easily adapted for application on hydraulic devices having very different flow rates, such as the spouts of sinks, sinks and baths.
  • the main object of the invention is achieved by means of a water jet aerator comprising a water spraying device, an air intake, a mixing chamber and a flow orifice provided with means for regulating the jet.
  • the spraying device comprises a first element having at least one ring of relatively large openings, and a second element also having a ring of relatively large openings, superimposed on the first element so that the openings of the two elements correspond only on small parts adjacent to the edges, thus determining a plurality of restricted passage openings.
  • composition of the spraying device with two elements also makes it possible to also achieve the auxiliary object of the invention, which can be achieved by preparing a plurality of second elements, superimposable on the first element of the spraying device and having different characteristics, or alternatively by providing for the possibility of superimposing the second element on the first in different positions, or even, in certain cases, by the simple omission of the second element.
  • the openings of the two superimposed elements are preferably arranged so that the opposite edges of each opening of an element form restricted passage openings with the contiguous edges of two successive openings of the other element.
  • each light produces a small inclined jet which converges towards the jet, inclined in the opposite direction, of the contiguous light, so that the two jets spray reciprocally when meeting, without the need for the presence of a wall. .
  • This ensures high spray efficiency and re subsequently reduces noise. Since the spraying by reciprocal shock of jets is carried out, in this case, in a plurality of points arranged in a crown, the air can penetrate freely between the different jets and it is then entrained by the sprayed flow, even if no do not use a stabilization sphere or similar body capable of producing Venturi suction.
  • the number 1 indicates the aerator body, consisting of a socket which ends at the top with a thread 2 for mounting on the end of a hydraulic device.
  • a cylinder 3 In the bush 1 is mounted a cylinder 3, the lower end of which defines a flow opening provided with threads 4 for regulating the jet; on the threads 4, a mixing chamber 5 is formed in which the ambient air can arrive through openings 6 made in the wall of the cylinder 3 and through the gap defined between the cylinder 3 and the sleeve 1.
  • These parts are characteristic of most aerators and must not be modified for the application of the invention, they can therefore be of any type. what kind and shape.
  • the mixing chamber 5 is closed above by a first element 7 substantially in the form of a disc having a ring of openings 8, in this case equidistant circular holes arranged on a single circumference.
  • the holes 8 have a diameter large enough to allow easy manufacture, for example by molding of plastic material, of the element 7.
  • the disc 7 preferably forms a cavity for placing the second element of the sprayer therein.
  • the second element of the sprayer is in turn formed by a disc 11 also having a ring of openings 12, in this case circular holes in number equal to the number of holes 8 of the first element 7 and arranged on a circumference of the same diameter .
  • the holes 12 also have a diameter large enough to allow easy manufacture, for example by plastic molding, of the element 11; moreover, in the form shown, the holes 12 are smaller than the holes 8.
  • the diameters of the holes 8 and 12, the diameter of the circumference on which they are arranged and their number, are chosen so that, when the two discs 7 and 11 are superimposed with the respective holes 8 and 12 offset, as shown in FIG. 1, the opposite edges of each hole of one element form restricted passage openings with the contiguous edges of two successive holes of the other element.
  • the lights formed are, in number, twice the number of holes of each element, and they can be proportioned to the most severe requirements of an aerator for small flow, for example for washbasin, whose requirements of ventilation and silence are the most rigorous.
  • the disc 11 has a handle 13 for gripping it and it is provided with a centering stud 14 which can be introduced into one or the other of two corresponding holes 9 and 10 presented by the disc 7 ( Figures 1 and 2).
  • this arrangement which serves as an example, could be replaced by a non-circular conformation of the elements 7 and 11, or by other means of mutual reference, however arranged.
  • holes 8 and 12 have been illustrated as circular, they can, of course, be replaced by openings of any shape, for example rectangular; however the circular conformation of the holes determines, by their mutual intersection, narrow passage lights of biangular shape, particularly effective for this application.
  • these elements can be fixed to each other definitively during manufacture and, in this case, the mutual references 9, 10 and 14, as well as the grip 13, can be omitted.
  • a gasket 15 is normally superimposed on the device described, for mounting without losses in a flow spout.
