<p>The device (1), which provides for both full and partial discharge, is of the type in which a movable member (11), fitted with a valve (10), has a float (14) for delaying return of the valve to the closed position, and an additional member (31) is selectively connectable to the movable member (11) to accelerate closure of the valve. According to the invention, the additional member (31) is connected to the movable member (11) by a rocking body (40) hinged to a support (38) carried by the additional member (31); and the rocking body (40) has, at respective ends, a buoyancy member (45) and a hook (46) which engages a respective seat (28) on the movable member (11), so that the additional member (31) is connected automatically to the movable member (11) alongside a variation in the level of the water in the tank. <IMAGE></p> |
