Definitions

  • This invention relates to an air/water mixing nozzle suitable for use in spa baths or the like.
  • Air/water mixing nozzles are commonly used in spa baths or spa pools of the type where air is mixed with water and injected into the bath under pressure to provide a massage jet effect and to aerate the bath.
  • the term 'spa bath' is to be taken to include all similar constructions of this type including spa pools and other similar arrangements.
  • the invention provides an air/water mixing nozzle including an inlet (10) for water, a jet (6) for supplying water from said inlet to an air/water mixing chamber (5) having an air inlet (16), and an outlet (13) from said mixing chamber (5) characterized in that a fairing member (12) is provided in said inlet (10), said fairing member (12) serving to direct the flow of water to said jet (6).
  • an air/water mixing nozzle for a spa bath is constructed as follows:
  • An air inlet 16 is provided into the chamber 5 and in the preferred form of the invention the air inlet comprises an upwardly extending conduit 17.which is open to the atmosphere at its upper end 18.
  • the air inlet conduit 17 extends upwardly to the upper flange (not shown) of the spa bath where is terminates in a simple air inlet control valve.
  • the adjustable nozzle outlet 15 comprises a cylindrical socket 19 in which is mounted a jet.20 having a spherical outer surface 21.
  • the diameter of the jet 20 is slightly less than the diameter of the socket.l9 so that the jet forms a sliding and tilting fit within the socket.
  • the jet is mounted within the socket by way of two sealing rings 22 and 23 which.are.wedged shaped in cross-section and serve to support and seal the jet within the cylinder 19.
  • the cylinde is provided a first flange 24 and a second flange 25 and a compression spring 26 axially arranged within the cylinder.
  • the first sealing ring 22 abuts the first flange 24 and the second sealing ring 23 is held in position by an axial force provided by the spring 26 acting between the ring 23 and the second flange 25.
  • the entire nozzle outlet 15 is conveniently located within the remainder of the nozzle by a screw thread 27.
  • the nozzle outlet jet 20 incorporates a central passage 28 therethrough for the passage of water and air from the chamber 5 to the interior 14 of the spa bath.
  • the passage 28 is preferably circular in cross-section and converging from its inlet end adjacent the chamber 5 to its outlet end 29.
  • the air/water mixing nozzle 3 operates as follows. Water entering inlet 10 impinges on fairing member-12, which serves to direct water passing through inlet into the central jet 6, from which it issues at high velocity into the chamber 5.
  • air from inlet 16 is mixed with water which spreads out into chamber 5 after being injected from jet 6.
  • the air/water mix then exits through converging nozzle central passage 28 at high velocity.
  • Central jet element 6 is adjustable, as described hereinbefore. Adjustment towards outlet 29 results in less air being entrained in the water, and adjustment away from the outlet results in more air being entrained.
  • the air/water mixing nozzle 3 includes a pipe 9 extends into main pipe 2, the pipe being provided with an inlet 10.
  • a crossbar 11 (Fig. 4) is provided across inlet 10, and on the crossbar 11 is mounted a fairing member 12, which may typically be conical in configuration.
  • a central jet element 6 Adjustably mounted within pipe 9 is a central jet element 6.
  • the element 6 has external screw threads which co-operate with internal screw threads on pipe 9 such that rotation of element 6 will advance it towards inlet l0.or retract it from the inlet.
  • the central jet 6 has a converging inlet portion 8 which communicates with a reduced diameter (in comparison with the diameter of pipe 9) aperture 7, which itself communicates with an air/water mixing chamber 5.
  • the chamber 5 has an outlet 13 located directly opposite the jet 6, and the outlet 13 communicates with the interior 14 of a spa bath by way of an adjustable outlet nozzle 15.
  • an air/water mixing nozzle for a spa bath which has been found to be extremely effective in mixing air with water and capable of achieving a higher air:water ratio than has been achieved with previous nozzles.
  • the nozzle has also been found to give a greater penetration of the air water mixture into the spa bath than previously achieved which results in a superior massage effect and greater aeration of the water within the spa bath.
  • the adjustable nozzle outlet has been found to be simple and therefore cheapto manufacture and-result in an adjustable nozzle which is simple to operate, as the jet 20 can turn and tilt freely within the cylinder.19, * and furthermore has a long life with little component wear.
