Definitions

  • the present invention refers to a watering sprinkler of the multi-function kind that is adapted to be connected, by means of a fit-in coupling and possibly a connector, to a water hose for the irrigation of gardens and the like.
  • Multifunction-type watering sprinklers are usually constituted by an appropriately contoured body that comprises a spray head provided with nozzles for issuing a jet of liquid, i.e. water under pressure.
  • the spray head of a multi-function watering sprinkler is provided with a surface with a plurality of small-diameter perforations that produce a diffuse jet, and with a central nozzle with a larger diameter that generates a concentrated jet.
  • the spray head of a multi-function watering sprinkler comprises, further to said perforated surface, two or more nozzles having different diameters which enable jets of a differentiated form (i.e. a straight jet, a fanlike spreading jet, an atomized jet, etc.) according to the particular kind or pattern of irrigation required.
  • the selection of the various kinds of jets of a multi-function watering sprinkler is done by accordingly rotating a ring nut, which the sprinkler head is provided with.
  • a ring nut By rotating such a ring nut, in fact, the nozzles corresponding to the required kind of jets are selectively opened and closed.
  • watering sprinklers have been developed, which are provided with adjustment devices, such as for instance cock-like devices or push-button devices, so as to be able to vary both the form of the jet and the flow-rate thereof.
  • adjustment devices such as for instance cock-like devices or push-button devices
  • a further purpose of the present invention is to provide a multi-function watering sprinkler of the above cited kind, which is as simple and reliable as possible.
  • the watering sprinkler according to the present invention comprises a shaped body 10, which is provided on the rear with a fit-in coupling 11 for connection with a water supply hose (not shown) and, on the front side, with a water delivery head 12 that is closed by a surface provided with a plurality of perforations (see Figures 1 and 4).
  • the shaped body 10 is made in the form of a shell ( Figure 2) which, at its rear end portion, closes up around the tang or tail piece of the fit-in coupling 11 and, at its front end portion, engages the head piece 12 and the end portion of a conduit 13 that forms the extension of the fit-in coupling 11 into the body 10.
  • a valve member 14 that comprises a perforated pan or disk 15 ( Figure 3).
  • This disk 15 is supported by a pin 16 that protrudes from the body 10 and is capable of being actuated rotatably about its axis by means of a lever 17.
  • This lever 17 is preferably snap-fitted onto the pin 16.
  • the disk 15 is provided with two substantially opposite perforations 18 and 19 so as to selectively enable, through the rotation of the pin 16 by means of the lever 17, the fit-in coupling 11 to be switched into communicating with two conduit branches 131 and 132, into which the conduit 13 shoots out downstream of the valve member 14.
  • the disk 15 can be rotated into a further position, lying at an intermediate point between the above-cited ones, in which both branches 131 and 132 of said conduit are shut off.
  • the valve member 14 also acts as a shut-off valve for the watering sprinkler.
  • the flow conduits 131 and 132 are essentially co-planar with respect to each other and the fit-in coupling 11. Furthermore, the disk 15 of the valve member 14 is arranged on a plane that lies substantially parallel to the one containing the axes of said conduits 131 and 132 and said fit-in coupling 11. The pin 16 of the valve member 14 is orthogonal to the disk 15 of said valve member.
  • An essential feature of the watering sprinkler according to the present invention lies in the fact that the delivery head 12 thereof is provided with two separate perforated surfaces 21 and 22 (see in particular Figure 4), which close the outlet openings of the two flow conduits 131 and 132 formed in the body 10. These surfaces are fastened by means of screws 23 ( Figure 2) to the outflow openings of said conduits 131 and 132.
  • the surfaces 21 and 22 themselves are substantially co-planar and have perforations that have substantially the same diameter. However, they feature different or, more exactly, opposite curvatures. In fact, while one of these surfaces has a concave contour, the other one has a convex contour. It has been found experimentally that such a solution proves effective in producing two definitely differentiated kinds of water jets, i.e. a diffuse jet from a surface and a concentrated jet from the other one. The selection of either one or the other kind of jet, which is carried out by the rotation of the lever 17, is indicated by corresponding marks provided on the body 10 ( Figure 1).
  • differentiated water jets can also be obtained by providing the second delivery surface 22 with a planar contour, instead of a convex one. In this case, such a surface 22 will deliver a diffuse jet, whereas the concentrated jet will be issuing from the first surface 21.
