Definitions

  • the present invention relates to a device in shower heads and more particularly, a device for limiting the amount of water wing through the shower head.
  • shower head is meant a device transforming a uniform flow of water into a shower, which device may consist for instance, of a so called hand shower.
  • the single figure of the drawing is a schematic sectional side view of a portion of a shower grip comprising the device of the invention.
  • the rear end of the shower grip 1, not shown in the figures, is provided in the usual way with a connection for a hose which in turn is connected to a water conduit provided with a tap.
  • the front end of the shower grip 1 is provided with a sprayer 2.
  • the shower grip 1 is provided with a duct 3 through which water is intended to flow in the direction of the arrow A.
  • the duct 3 suitably has a circular cross section and at its left end has a restriction 4 before terminating in a substantially cone-shaped space 5.
  • An ejector valve 7 with a substantially circular cross section is integrated in or, alternatively, detachably
  • valve 7 inserted in the duct 3 and is prevented from turning therein owing to the restriction 4 and the front end of the valve 7 interacting therewith not being circular in shape.
  • the rear end of the valve 7 is provided with an annular resilient flange 8 which sealingly bears on the side walls of the duct 3.
  • the valve 7 may be provided with means for retaining same axially in the duct 3, however, usually this is not required, since the water pressure acting on the flange B urges the valve against the restriction 4.
  • the ejector valve 7 which has no movable parts, is provided with an axial duct consisting of coaxial subducts 9a and 9b. the cross sections of which are smaller than that cf the duct 3, thereby limiting the water flow passing through the valve.
  • the duct 9b is delimited by a metal tube attached in the valve 7 which is suitably made of plastic, the left-hand end of the metal tube protruding into the subduct 9a having the larger cross section.
  • a radial air duct 10 in the side wall of the valve 7.
  • the extension of the central axis of the duct 10 is located in the same plane as, or at a short
  • the inlet of the duct 10 is located at a great distance from the hole 6 in the side wall of the grip 1, suitably diametrically opposed same, as appears from the figure.
  • the inlet of the duct 10 communicates with the annular space 11 formed between the valve 7 and the side wall of the duct 3, which space is filled with air and extends between the restriction 4 and the flange 8.
  • the water flow fed through the duct 9b in the direction of the arrow A is mixed with the air flow induced through the duct 10 by means of the ejector effect in the area immediately after the left-hand end of the tube 9b.
  • the water/air flow passes through the duct 9 and further into the space 5 and is then pressed out through the sprayer.
  • a desired admixture of air of 20 - 30% to the water is achieved. This essentially gives the same showering effect as with water only as well as softer sprays, while reducing water consumption by 20 - 30%.
  • Owing to the duct 9b having a substantially smaller cross section than duct 3 water consumption is further reduced, an totally more than 50% and as much as 70% of water consumption may be saved as compared to conventional shower grips with substantially retained showering effect.
  • the hole 6 is covered by a finger of the hand holding the shower grip 11. If the hole 6 is covered
  • valve 7 is located as close to the sprayer as possible. The reason is that the ejector effect of the valve 7 will be better, since the point of mixture between water and air is located near the outlet for the water/air mixture, and that on shutting off the water flow to the shower grip 1 there will be a small amount of water therein downstream of the valve, which reduces the risk of water being spilt.
