<p>A feed valve (1) for a flush tank, having an extensible outlet pipe (6) defined by two telescopically connected tubular members (11, 12); the tubular members (11, 12) slide freely with respect to each other along a predetermined axis (13) by virtue of an axial load, and have stop means (21, 22) for limiting axial slide of the tubular members (11, 12) between an extracted maximum-telescopic-extension position and a withdrawn minimum-telescopic-extension position; the radially inner tubular member (11) has, at one end (16), an end opening (34) defined by an oblique peripheral end edge (35) to permit outflow of water from the outlet pipe (6) even when the end (16) rests on a bottom wall (32) of the tank (2). <IMAGE></p> |
