<p>Mechanism for the filling and emptying of the water tank of water closets, made up by a drive group (1) which actuates two pulling chains (3) one of which rises the drain buoy (4) for the discharge of the tank, and the other chain actuates over the axle (9) inclining it and unblocking the valve (7) making it possible the entrance of water, whilst the drain buoy (4) falls by gravity. Once the filling has been completed, the floater (10) places the axle (9) vertically, closing the valve (9). The assembly has available a pressure reducer (11) and anti-return valve (12) which vertical fall perfectly fits a valve washer (13) due to its conical coincident shapes. The mechanism allows its alternative actuation from the front part of the tank or from the upper part through the variation of the drive lever (2) by the drive arm (2A).</p> |
