Abstract (en)

The flush valve comprises an upper valve (3) and a lower valve (7) connected in series and mounted on a tube (2) of different sections. Operating the pushbutton up to half of its way pulls up a filar element (1) fixed to said tube (2) thus moving it and opening the upper valve (3) which makes water pass from the toilet bowl tank through inlet holes (b) and circulation holes (c) into the main tube (4). During the operation, the tube (2) remains guided within a hub-hole (d) in the cover (5) and within the centering device (6). The operation of the pushbutton all the way down, displaces the tube (2) upwards dragging the upper valve (3) fitted to it and the cover (5) to open the lower valve (7) being fixed to the main tube (4) at the lower external end. The displacement is directed by a guide (8) and enables emptying the entire toilet bowl tank. The above mentioned guide (8) and a retainer (10) which closes the passage towards the downpipe (e) are both connected to the lower valve seat. Said seat (9) provides several holes (f) for drainage of the water contained in the toilet bowl tank.
