Abstract
A valve (3) for a toilet cistern including means for substantially preventing water refilling the cistern until substantially all the water in the cistern has been discharged. Preferably the means includes a separate chamber (7) provided within the cistern and a float operated inlet valve (3), the float (1) of which floats on the surface of water contained in the chamber (7). The chamber (7) includes an outlet (8) through which the water is discharged more slowly than water is discharged from the cistern.
Claims
1. A means suitable for use in a toilet cistern automatically to control the opening of the water inlet to the cistern until water initially in the cistern has been substantially discharged.
2. A means according to claim 1, comprising a chamber (7) including a permanently open outlet (8) through which water contained in a chamber (7) drains at a rate slower than the rate at which water is discharged from the cistern, and is arranged so that, in use, the float (1) of a float valve floats on the surface of the water in the chamber (7) .
3. A means according to claim 2, in which the outlet of the chamber is a permanently open orifice (8) .
4. A means according to claim 1 or 2 , in which the rate at which water flows from the chamber (7) is variable.
5. A means according to claim 4, in which the flow rate is varied by providing a variable size orifice (8) .
6. A means according to claim 5, in which the size of the orifice (8) is varied by providing a plurality of plugs having different diameter through-holes which can be fitted into a fixed aperture, or by providing a plurality of orifices one of more of which may be closed to vary the rate which water is discharged from the chamber (7) .
7. A means according to any one of claims 2 to 6 , in which variable means (4,6,9) are provided to vary the height of the chamber with (7) respect to the bottom of a cistern.
8. A means according to claim 7, in which the chamber (7) is mounted on a vertical guide (9) , and includes a means (6) to releasably secure the chamber (7) at locations along the vertical guide (9) .
9. A means according to claim 7 or 8 , in which the chamber (7) is also horizontally movable with respect to the vertical guide (9) to allow the float (1) to be positioned centrally within the chamber (7) .
10. A toilet cistern including a means in accordance with any one of the preceding claims, and a float operated water
