<p>A float acts on the closing element via a lever arm mounted on the valve to swivel up and down, on the inflow valve attached to a lavatory flushing cistern. The valve (20) incorporates a fixed (6) and a movable (10) ceramic control disc plate, the latter being directly engaged by the lever arm (16, 14). The plates are pref. sited in vertical planes, while the lever arm has a horizontal extension engaging an external opening (12) in the movable plate.</p> |
