Abstract
The fill valve incorporates a housing (8) that has a vertical water-carrying channel (24) that leads from an inlet (49) to be fastened on the flush tank bottom (2) to a float-controlled diaphragm valve (50). The diaphragm valve (50) incorporates in a diaphragm (43) a passage for the pressure equalization between a first chamber (51) in front of the diaphragm (43) and a second chamber (52) behind the diaphragm (43). To actuate the diaphragm valve (50) a pilot valve (58) is provided. The diaphragm valve (50) is disposed laterally on the housing (8), thus permitting a low overall height.
