(54)	Lavatory flush tank feed valve

(57) A lavatory flush tank feed valve (1) of the type having a valve assembly (4) housed in a body (2) and controlled by a main float (11) movable with respect to the body; an auxiliary float (31), carried by the main float (11), moves a corresponding retaining member (32), which engages and disengages a seat integral with the body to connect and disconnect the main float (11) and the body (2) alongside a variation in the level of the water in the flush tank. The feed valve thus withstands relatively high operating pressures (even over 20 bars) of the water mains to which it is connected, despite employing standard valve assemblies, and adapts automatically to different operating pressures with no major adjustment required in the level of the main float.
