- It may be arranged that said sprayplate assembly is provided with a radially extending projection for facilitating rotary movement thereof.
- An exemplary embodiment of the invention will now be described reference being made to the accompanying drawings, in which:
- Fig. 1 is an exploded view of a spray head in accordance with the present invention;
- Fig. 2 is a somewhat diagrammatic cross-sectional view of the outlet part of the spray head of Fig. 1;
- Fig. 3 is a diagrammatic plan view of the sprayplate of Fig. 1; and
- Figs. 4 to 6 are diagrammatic plan views of the sprayplate of Fig. 1 shown in each of its three positions.
- The spray head shown in Fig. 1 comprises a
hollow body 1 having a threadedportion 2 at one end for connection to a water supply pipe (not shown). The other end of thebody 1 is provided with anoutlet hole 3 in which is located ahollow sprayplate 4 formed by an outerperforated plate 5 and aninner plate 6. Theinner plate 6 and a generallycylindrical boss 7 are attached to theperforated plate 5 by means of a screw (not shown) which extends through acentral hole 8 in theboss 7 and in theinner plate 6 and engages acentral boss 9 in the centre of theperforated plate 5 into which it is screwed. Within thebody 1 and coaxial with theoutlet hole 3 is disposed acircular support structure 10 which is secured to thebody 1 by means ofscrews 11. Thesupport structure 10 is provided with acentral aperture 12 which is adapted to receive thecylindrical boss 7 attached to thesprayplate 4. Theaperture 12 is provided with three circumferentially spaced cut-outs 13 which correspond to three circumferentially spacedradial protrusions 14 provided on theboss 7. Thesprayplate 4 is attached to thebody 1 by inserting theboss 7 of thesprayplate 4 into theaperture 12 in thesupport structure 10, so that theradial protrusions 14 on theboss 7 align with the cut-outs 13 in thesupport structure 10, and by rotating thesprayplate 4 so that theprotrusions 14 engage with a back surface of thesupport structure 10 to retain it in position on thebody 1. One of the cut-outs 13 in thesupport structure 10 and a corresponding one of theradial protrusions 14 on theboss 7 is made smaller than the others, so that thesprayplate 4 may be attached to thebody 1 in only one angular position thereof. A sealing ring (not shown) would be provided between thesprayplate 4 and the rim of theoutlet hole 3 in thebody 1. - The hollow interior of the
sprayplate 4 formed between the outerperforated plate 5 and theinner plate 6 is divided into two separate chambers by means of acircumferential wall member 15 in the outerperforated plate 5 which aligns with aring sealing gasket 16 provided within the periphery of the rim of theinner plate 6, and by means of ashaped wall member 17 provided on the outerperforated plate 5 which aligns with a similarlyshaped sealing gasket 18 provided on the inside of theinner plate 6. Thewall members inner chamber 19 and anouter chamber 20 between the outerperforated plate 5 and theinner plate 6. Theinner chamber 19 is provided withperforations 21 in the outerperforated plate 5, the size, number, and positioning of which are chosen to afford a desired water spray pattern from the spray head, and similarly theouter chamber 20 is provided withperforations 22 in the outerperforated plate 5, the size, number, and positioning of which are chosen to afford a different water spray pattern to that afforded by theperforations 21. - An adjustable spray pattern is afforded by the spray head thus far described by controlling the flow of water to the
chambers chamber 19 only, one spray pattern is obtained, when water is supplied tochamber 20 only, a second spray pattern is obtained, and when water is supplied to both of thechambers 19 and 20 a third spray pattern is obtained. - Control of water flow from the
body 1 of the spray head to one or other or both of thechambers apertures inner plate 6 which open into theinner chamber 19 andouter chamber 20, respectively, and by means of a pair of spring-loadedresilient sealing balls 25 mounted on thesupport structure 10 secured to thebody 1, it being arranged that thesealing balls 25 bear on the outer surface 6' of theinner plate 6, and thesprayplate 4 is rotated relative to thebody 1 to cause the pairs ofsealing balls 25 to be moved into and out of sealing engagement with the pairs ofapertures inner plate 6. A radially disposedhandle 26 is provided on the outerperforated plate 5 to facilitate adjustment of thesprayplate 4 to the required setting. Thesupport structure 10 also carries a spring-loadedmetallic index ball 27 which engages with spaced depressions (not shown) provided in the outer surface 6' of theinner plate 6 in order to define the different angular positions of thesprayplate 4. - The pair of
sealing balls 25 and theindex ball 27 are disposed in a triangular configuration to equalise the pressure on the surface 6' of theinner plate 6 and have the advantage that as thesprayplate 4 is rotated, thesealing balls 25 are each also rotated, thereby causing them to be self-cleaned. - A generally
cylindrical filter 28 is provided extending around thecircular support structure 10 in order to filter the water fed to thesprayplate 4. - It will be appreciated that the simple construction of the spray head which has been described, based on very few parts, enables an easily adjustable spray head to be obtained, which is easily dismountable for cleaning purposes.
- In Fig. 2 of the drawings there is shown a somewhat diagrammatic view of the outlet part of the spray head already described with reference to Fig. 1. The
body 1 is provided with athrough bore 29 which conveys water from the threaded portion 2 (Fig. 1) to the area surrounding thefilter 28. Water filters through thefilter 28 into the general area above thecylindrical support structure 10 which is secured to thebody 1 such as by thescrew 11. - The
support structure 10 is provided with a spring-loadedindex ball 27 which engages with an indexingdepression 30 provided in the surface 6' of theinner plate 6 of thesprayplate 4. The general construction of the spring-loadedsealing balls 25 also provided on thesupport structure 10 may be the same as that of theindex ball 27. - The
sprayplate 4 comprises the outerperforated plate 5 which has theinner plate 6 and the centralcylindrical boss 7 secured to it by means of ascrew 31, one of theradial protrusions 14 being shown. The outerperforated plate 5 is provided with thecircumferential wall member 15 which engages with thering sealing gasket 16 of theinner plate 6, and with theshaped wall member 17 which engages the shapedsealing gasket 18 of theinner plate 6, thereby to form theinner chamber 19 and theouter chamber 20. One of the pair ofapertures 23 to theinner chamber 19 is shown in theinner plate 6. In the position shown in Fig. 2, theaperture 23 is not in engagement with one of the sealing balls 25 (not shown in Fig. 2) so water is free to pass through theaperture 23 into theinner chamber 19 and out through theperforations 21 in the outerperforated plate 5 corresponding to theinner chamber 19. By rotating thesprayplate 4, by means of thehandle 26, theapertures 23 can be brought into sealing engagement with the pair ofsealing balls 25, in order to prevent water flow into theinner chamber 19. - In Fig. 3 of the drawings there is shown a diagrammatic plan view of the
sprayplate 4 of Fig. 1. Thesprayplate 4 includes the outerperforated plate 5 having theperforations inner chamber 19 andouter chamber 20 respectively. The outerperforated plate 5 has thecircumferential wall member 15 and theshaped wall member 17, shown in dashed lines, defining theinner chamber 19 andouter chamber 20, and the pair ofapertures 23 corresponding to theinner chamber 19 is shown as is the pair ofapertures 24 corresponding to theouter chamber 20. The index depressions in the surface 6' of theinner plate 6 are also shown at 32. - In Figs. 4 to 6 of the drawings there is shown diagrammatic plan views of the
sprayplate 4 of Fig. 1 in each of three different positions, and showing more specifically the disposition of thesealing balls 25 andindex ball 27 relative to the pairs ofapertures - In Fig. 4, the
sprayplate 4 is shown in its mid-position in which thesealing balls 25 are both disposed betweenadjacent apertures apertures inner chamber 19 and theouter chamber 20 whereby water is emitted by all of theperforations 21 and 22 (Fig. 3). In this position theindex ball 27 aligns with one of theindex depressions 32. - In Fig. 5, the
sprayplate 4 is rotated counterclockwise relative to that in Fig. 4, in which the pair ofsealing balls 25 are in sealing engagement with theapertures 24, thereby preventing water supply to theouter chamber 20. Water is therefore fed only to theinner chamber 19 viaapertures 23 so that water is emitted only from the perforations 21 (Fig. 3) corresponding to the inner chamber. In this position theindex ball 27 aligns with another of theindex depressions 32. - In Fig. 6, the
sprayplate 4 is rotated clockwise relative to that in Fig. 4, in which the pair of sealingballs 25 is in sealing engagement with theapertures 23, thereby preventing water supply to theinner chamber 19. Water is therefore fed only to theouter chamber 20 viaapertures 24 so that water is emitted only from the perforations 22 (Fig. 3) corresponding to theouter chamber 20. In this position theindex ball 27 aligns with yet another of the index depressions 32. - It will be appreciated that the spray head which has been described has been given by way of example only and may be modified to suit any particular application. For example, the
hollow sprayplate 4 may be divided into more than two chambers, thereby affording a greater number of spray patterns. Although the provision of spring-loaded sealingballs 25 has been provided other means of sealing thefeed apertures sprayplate 4, the sealingballs 25 could be in sealing engagement with one of each of the pairs offeed apertures sprayplate 4.
