Definitions

  • This invention relates to an improvement in a swivelling type, orientable nozzle particularly suitable for use in saunas and similar equipment calling normally for the delivery of steam.
  • nozzles are commonly known to be suitable for use in such equipment as whirlpool bath-tubs, shower cabins, etc.
  • all such nozzles are rather complicated since they require the availability of inner conduits which shall enable different liquors and gases to be both mixed and/or excluded selectively. They may also require check valves to be appropriately included or built-in to prevent the liquor circulating in the equipment from becoming contaminated; they further require continuous maintenance for cleaning purposes.
  • a swivel-type, relatively uncomplicate nozzle for mixing air and water in applications in connection with a shower booth is disclosed in the Italian utility model no. 0 216 885.
  • This nozzle is formed by a body in which a seat is provided to partially accomodate, in a swiveling manner, an insert provided to eject the liquor under pressure.
  • Said insert is essentially spherical in its shape and comprises internally conduits that flow into corresponding perforations in the outer surface of the insert to generate the jets of liquor.
  • Each one of said conduits contains an injector through which air is drawn in owing to the effect of water flowing through the same conduit.
  • the insert itself is kept in position in its seat by means of a threaded ring that is screwed on to the body, while a water-tight sealing ring is mounted between the insert and its seat.
  • a swivel nozzle for use in saunas or similar equipment, comprising a body, which is connected with the supply of working medium, and an insert, which is housed inside said body and retained in its seat by an annular face plate screwed on the aperture of said body.
  • the nozzle is provided with an internal bushing in order to vary the velocity of the volume of delivered fluid, so as it is necessary a special tool for removing and changing the bushing.
  • the insert has a substantially semi-spherical shape and is mounted in the body by means of elastic means acting against a matching element coupled with the insert. Therefore, the nozzle of said US patent suffers for the same drawbacks of the above mentioned prior art, as a noticeable friction develops between the relevant contacting surfaces and scale can interest the same surfaces making difficult or impossible to swivel the nozzle in the long run.
  • the nozzle shown in the Figures is substantially constituted by following elements:
  • the insert 5 has, on its side from which the working medium flows out, a recess 10 on the bottom surface of which perforations 6 are drilled.
  • the aperture of the recess 10 is flush with the outer profile of the annular locknut 7.
  • an annular sealing gasket 11 is provided between the annular locknut 7 and the outer edge of the body 1 between the annular locknut 7 and the outer edge of the body 1 between the annular locknut 7 and the outer edge of the body 1 there is provided.
  • Said elastic element 8 is in a preferred way constituted by a plastic spring being frusto-conical in its shape and having a base 12 that is closed and recessed so as to constitute a seat for the element to rest upon the pin 4.
  • a plastic spring being frusto-conical in its shape and having a base 12 that is closed and recessed so as to constitute a seat for the element to rest upon the pin 4.
  • three tips 13 are provided integrally therewith, said tips extending axially with the perforations 6 of the insert 5 and being adapted to move into said perforations when the insert 5 is pressed against the inner side of the body 1, so as to perform a self-cleaning of said perforations 6 when the nozzle is operating.
  • a projecting seat 51 (Figure 2) , being preferably triangular in its cross-section
  • a projecting pin 81 ( Figure 3), being also correspondingly triangular in its cross-section, so as to couple the spring and the insert with the correct orientation.
  • the nozzle 1 is mounted in an opening in the wall 14 of the equipment and is fastenend thereto by means of the annular locknut 7 and a further locknut 15, which is screwed on to the outer surface of the body 1 and is provided with a corresponding threading 16.
  • the nozzle according to the present invention is extremely simple in its construction, featuring a relatively small number of mouldable plastic component parts. It further turns out to be very convenient and reliable in its use.
  • the insert 5 is mounted elastically in the body 1 and its orientation can be performed, ie. it can be swivelled, under a minimum of friction. Furthermore, when the nozzle is operating, the perforations 6 of the insert 5 are cleaned in a practically automatic way thanks to the presence of the tips 13 inside the spring 8.
