Definitions

  • the present invention refers to a sprinkler provided with adjustable water spray jets, adapted in particular for use in gardening applications to water cultivated land, such as lawns or gardens, in which there may grow also trees.
  • sprinklers There are many kinds of sprinklers currently known in the art, ie. fixed, rotating, pulsating and oscillating sprinklers, wherein they differ from each other on the basis of the type of water jets that they produce. However, all of them are substantially constituted by an element which, duly provided with one or more nozzles, is adapted to issue water that is supplied to it through a water turbine from a water supply source to which the same sprinkler is connected via a flexible hose.
  • the sprinklers themselves can either be fixed into the ground by means of a proper spike or be mounted on a base framework that simply rests on the ground.
  • Fixed-jet sprinklers are the simplest ones and are capable of watering surfaces that may be variously shaped, but must not be too large in their size, by selecting or replacing the spray nozzles correspondingly.
  • Rotary sprinklers along with pulsating ones, are more complicated in their construction and operation owing to the need arising for a movement to be imparted to the spray jets, and therefore the heads or arms that carry the spray nozzles. Such a movement is generally brought about, through the provision of a transmission mechanism, by the same water turbine that supplies the spray nozzles.
  • These types of sprinklers are adapted to water circular surfaces, either completely or pardally, which are generally larger than the ones that can usually be irrigated with the afore cited fixed sprinklers.
  • a sprinkler provided with adjustable water spray jets which comprises, as recited in the appended claim 1, a base framework for it to rest on the ground, said framework supporting a pipe provided with water spray nozzles and a turbine-type drive assembly, which are connected to a water supply source, in which between said turbine-type drive assembly and the spray pipe there is installed a device for adjusting the flow rate of the supply water.
  • a sprinkler according to the present invention is illustrated in particular in Figures 1 and 2.
  • the sprinkler is substantially constituted by: a framework 10, which enables the sprinkler to rest on the ground; a rectilinear pipe 11, provided with a plurality of nozzles 12, which is mounted in a fixed position with respect to said framework 10; and a hydraulic turbine-type drive assembly 13, secured to the framework 10, which is provided with a water inlet connector 14 ensuring the water supply to the spray pipe 11.
  • the support framework 10 is of a traditional type, comprising two appropriately shaped end portions 15 and 16, in which the first one is adapted to allow for the mounting of the drive assembly 13 and the second one is adapted to accommodate the extremity of the spray pipe 11 that is opposed to the one connecting the latter to said drive assembly 13. Said end portions 15 and 16 are joined and connected together through tubular members 17 that are fined into appropriate receptacles provided in the same end portions. The extremity of the spray pipe 11 that is opposite to the one connecting the latter with the drive assembly 13 is normally shut by a cap 30.
  • the drive assembly 13 enclosed in a box-like casing, comprises a horizontal-axis water turbine 18 that is operated by the water under pressure that flows in through the water inlet connector 14.
  • the latter is adapted to be connected, for instance, to the water supply source by means of a flexible hose (not shown).
  • This water inlet connector 14 extends into the drive assembly 13 and has an aperture 19 for the water to flow therethrough, in which said aperture is arranged in such a manner as to enable the water jet to hit the blades of the turbine 18 radially.
  • a threaded reel 21 On the shaft 20 of the water turbine 18 there is provided a threaded reel 21 that is rotatably engaged by a gear 22 which is firmly joined to an extremity of a cylindrical pipe 23.
  • the latter is capable of rotating inside of a cylindrical housing 24, which is firmly associated to the casing accommodating the drive assembly 13 and extends coaxially inside the water spray pipe 11.
  • an aperture 25 In the cylindrical wall of the pipe 23 there is provided an aperture 25, preferably in an elongated oval shape, having its major axis parallel to the central axis of the pipe 23.
  • an aperture 26 which has a progressively variable cross-section.
  • the two portions of the pipe 23 and the housing 24, which are so provided with said aperture 25 and said apertures 26 (the latter are in the number of two, in this case), respectively, are shown in Figure 3 as developed on a plane and in a side-by-side arrangement.
  • the apertures 26 have preferably a triangular shape and are arranged with a bisector B-B extending orthogonally to the major longitudinal axis L-L of the aperture 25.
  • the water flow rate varies progressively from a minimum to a maximum value.
  • the water flow rate is at a minimum when the aperture 25 of the pipe 23 is located in front of the closed, ie. solid wall of the housing 24.
  • the water flow rate is on the contrary at a maximum when said aperture 25 is located in correspondence of the base of the triangular aperture 26 opposite to the vertex V.
  • the term "sprinkler” shall not be understood as only indicating a device intended to water portions of ground, but rather any device issuing one or more water jets, such as for instance the jets of a fountain. Even in a case like this one, in fact, it may be of advantage to apply a flow-rate regulator for the jets.
  • the constant cross-section aperture 25 and the varying cross-section aperture 26 can exchange their position in the rotating pipe 23 and the fixed housing 24, respectively, since this would anyway produce as a result a variation in the flow-rate of the jets issuing from the sprinkler.
  • the sprinkler When stating that the sprinkler is a "fixed” one, it is meant that it remains in the same position during its operation; however, it can be easily appreciated that the water spray pipe 11 may be mounted in a different angular position, by rotating it about its own longitudinal axis A-A ( Figure 2), depending on the maximum flow-rate that is actually required for the jets G.
  • This adjustment of the inclination, or slope, of the jets issuing from the nozzles 12 is usually performed when the sprinkler is not being supplied with water. However, it can advantageously be performed when the sprinkler is regularly operating, as well.
  • the sprinkler generates unidirectional jets G (see Figure 1), so that the user can move near the sprinkler by approaching it on the opposite side of the jets, in order to adjust it without getting wet.
  • a particular variant thereof which does not depart from the scope of the present invention, is constituted by the possibility for a double sprinkler to be easily provided, in that two water spray pipes 11 are mounted in a parallel, side-by-side arrangement, said two pipes being able to be supplied by respective water-supply arrangements 22-26 driven by the same drive assembly constituted by the turbine 18, the shaft 20 and the reel 21.
