Abstract
A float valve device for a water cistern includes V-shaped water outlet ducting 6 whereof the limbs 8 diverge to terminate in outlet nozzles 10, whereby the float valve device is better able to fit into small cisterns. A float arm 12 has a float 14 adjustably mounted thereon by way of a clip 16. Formed through the float 14 is a slot which closely receives the clip 16. Both the float 14 and the clip 16 are elastic, so that a lower, curved flange of the clip 16 can be inserted downwardly through the slot until the flange is behind the underneath surface of the float 14, whilst a curved flange 28 of the clip 16 bears fittingly against the upper surface of the float 14. The clip 16 is thus releasably latched in position in the slot 22. Extending upwardly from the flange 28 is an arm 30 formed with sets each of a few teeth and at respective opposite edges of the arm 30. The clip 16 also includes a graspable elongate pulling pip at the free end zone of the arm 30. The float arm 12 is in the form of a channel section formed at the insides of its side walls with respective toothed racks 36 releasably engageable by the respective sets 32 of teeth on the arm 30, enabling adjustment of the position of the float 14 along the arm 12.
Description
METHOD AND APPARATUS
This invention relates to an adjustable apparatus, in particular to a float valve device, and to a method of adjusting the same.
According to one aspect of the present invention, there is provided an adjusting method, comprising restraining an elongate element and a second element against relative movement therebetween in any sense transverse to a longitudinal sense of said elongate element, resiliently disengaging one part of a rack-and-tooth adjustment device between the two elements from the other part of that device, producing relative sliding movement between the two elements in said longitudinal sense, so as to adjust said elements relative to each other in said longitudinal sense, and then resiliently re-engaging said one part with said other part to set said elements against relative sliding movement in said longitudinal sense.
According to another aspect of the present invention, there is provided apparatus comprising an elongate element and a second element, relative sliding movement between the two elements being possible in a longitudinal sense of said elongate element, but relative movement between said elements in any sense transverse to said longitudinal sense being restrained, and a rack-and-tooth adjustment device between the two elements and comprised of a first part comprised of a toothed rack on one of said elements and a second part comprised of at least one tooth on the other of said elements and engageable with the first part to obstruct longitudinal relative sliding between the two elements, one of the first and second parts being resiliently mounted on its associated one of said two elements so as to allow that one part to be disengaged from the other part, "hereafter said elements can be adjusted relative to each other in said longitudinal sense, "hereafter that one part can be re-engaged with said other part to set said elements against relative sliding movement in said longitudinal sense. . Owing to those two aspects of the present invention, the adjustment device between the two elements can be relatively 1,. Lo
simple and thus relatively inexpensive. Furthermore, the adjustment device can be relatively finely adjusted.
According to a third aspect of the present invention, there is provided a float valve device for controlling liquid flow and including a plurality of outlets therefrom for the liquid.
Owing to this aspect of the invention, it is possible, for the same maximum throughflow cross-sectional area, to enable the present device to fit into a more restricted space than a float valve device having only a single outlet therefrom for the liquid. The outlets are advantageously only a few in number, for example two.
Advantageously, the toothed rack is provided on the elongate element and the at least one tooth is provided on the second element. Preferably, the second element is slidable along the elongate element to perform the adjustment.
To restrain relative movement between the elements in any sense transverse to the aforesaid longitudinal sense, one of the elements may embrace the other, especially in an encircling manner.
The adjusting method and the adjustable apparatus are particularly applicable to float valves, with the elongate element preferably being a float arm of the valve and the second element being part of or attached to the float.
In order that the invention may be clearly and completely disclosed, reference will now be made, by way of example, to the accompanying drawings, in which: Figure 1 shows a perspective view from above of a float valve device, and Figure 2 is a view similar to that of Figure 1, but exploded, and showing some of the individual items of the valve device.
Referring to the drawings, the float valve device is for a water cistern, for example, and includes a water inlet 2 leading to a rotary valve 4 communicable with V-shaped water outlet ducting 6 whereof the limbs 8 diverge, progressing away from a water outlet of the valve 4, to terminate in respective downwardly directed water outlet nozzles 10, whereby the float valve device is better able to fit into small cisterns. Fixed to the rotary member of the valve 4 so as to extend radially therefrom is a float arm 12 which has a float 14 adjustably mounted thereon by way of a clip 16.
The float 14 has, to one side of the arm 12, an upper bulge 18 and, to the opposite side of the arm 12, a leg 20. An appropriately positioned weight 19 is provided in the bulge 18. Formed through the float 14 at a location between the bulge 18 and the leg 20 is a slot 22 which closely receives the clip 16. Both the float 14 and the clip 16 are elastic, so that a lower, curved flange 26 of the clip 16 around a lower end of a slot 24 through the clip 16 can be inserted downwardly through the slot 22 until the flange 26 is behind the underneath surface of the float 14 at the lower end of the slot 22, whilst a curved flange 28 around the upper end of the slot 24 bears fittingly against the upper surface of the float 14. The clip 16 is thus releasably latched in position in the slot 22. The clip 16 has extending upwardly from the flange 28 an arm 30 formed with sets 32 each of a few teeth and at respective opposite edges of the arm 30. The clip 16 also includes an elongate pip 34 projecting outwardly substantially parallelly to the axis of the valve 4. The float arm 12 is relatively rigid and is in the form of a channel section formed at the insides of its side walls with respective toothed racks 36 releasably engageable by the respective sets 32 of teeth on the arm 30.
The clip 16 is moulded in one piece of an elastomeric material, such as rubber or a polymer, such as polyurethane, which is flexible and has a memory. Adjustment of the position of the float 14 along the arm 12 is performed mainly at installation of the float valve device. The clip 16 enables the float to be set in the correct position on the float arm at the time of installation. To perform that setting, the pip 34 is manually pulled outwardly substantially parallelly to the axis of the valve 4, to disengage the teeth sets 32 from the toothed racks 36 and, after the installer has used the pip 34 to slide the float 14 along the arm 12 to its required position, he releases the pip 34, so allowing re-engagement of the teeth sets 32 with the toothed racks 36 and so preventing movement of the float 14 along the arm 12.
Among the advantages of the float valve device described with reference to the drawings are that the clip 16 can be moulded in one piece and thus relatively cheaply; that, if the clip 16 is moulded of an elastomeric material appropriate to the liquid the flow of which is being controlled by the valve device, the clip 16 will not be corroded by the liquid; and that by appropriate selection of the pitch of the teeth 32 and the teeth of the racks 36, the fineness of the adjustment of the float position can be predetermined. i,
