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.

A fill valve assembly for a flush tank, having a housing (8) that incorporates a vertical water-carrying channel (24) that leads from an inlet (49) that is to be fastened on the flush tank bottom (2) to a float-controlled diaphragm valve (50) that incorporates in a diaphragm (43) a passage for pressure equalization between a first chamber (51) in front of the diaphragm (43) and a second chamber (52) behind the diaphragm (43), and having a pilot valve (58) for actuating the diaphragm valve (50), wherein the diaphragm valve (50) is disposed laterally on the housing (8), wherein the water-carrying channel (24), at an upper end, leads into a horizontal passage (26) and wherein the first chamber (51) leads into an upwardly extending channel (53) and into a rotation chamber (54) for preventing water noises as water flows through the rotation chamber and into the flush tank and wherein the housing (8) has at a lower end means (16, 18) for fastening the valve assembly at the bottom of the flush tank.
A fill valve assembly for a flush tank having a housing (8) that incorporates a vertical water-carrying channel (24) that leads from an inlet (49) that is to be fastened on the flush tank bottom (2) to a diaphragm valve (50) that incorporates a first chamber (51) in front of a diaphragm (43) and a second chamber (52) behind the diaphragm (43), wherein the first chamber (51) is an annular chamber that extends in a vertical plane and is disposed laterally on the housing (8), which, when the diaphragm valve (50) is open, leads tangentially into a rotation chamber (54) that extends in a horizontal plane for preventing water noises as water flows through the rotation chamber and into the flush tank, wherein the water-carrying channel (24), at an upper end, leads into a horizontal passage (26) and wherein an annular outlet channel (28) is disposed downstream from the rotation chamber (54) and wherein the housing (8) has at a lower end means (16, 18) for fastening the valve assembly at the bottom of the flush tank.
