The invention relates to a water discharge valve practicable for toilet flushing cisterns, which valve is composed of the base 20, the base of the water discharge buttons 4 fixed, via an hypsometric axle 11 and two path adjusting means 9,10, at the centre of the base 20, a high-adjusted overflow pipe 13 bare of any external unnecessary accessory so that water discharge may be facilitated and the toilet bowl better cleaned up. The two path adjusting means 9,10 allow the horizontal and transverseadjustment of the path at the base of the water discharge buttons; the connection of the foregoing path adjusting means to the hypsometric axle 11 makes easier the disconnection of the whole base of the selection buttons 4 so that the overflow pipe may be removed and the sealing elastic ring 19 replaced. Two floats 15,16 allow the selection of the water quantity discharged into the toilet flushing cistern by making savings in water. A nut 23 is provided for the easy replacement of the valve. |
