Fluid Dispensing Device The present invention provides a device suitable for dispensing fluid from a source of fluid (1) to a reservoir. The device comprises a first one-way valve (7) through which fluid from the source may flow, a second one-way valve (11), connecting means (9) between the first and second one-way valves having a resiliently deformable portion, an abutment (15) and a float (23). The float, which preferably is pivotally movable with respect to the abutment, will move inresponse to a change in liquid level in the reservoir thereby causing the resiliently deformable portion of the connecting means to deform against the abutment so decreasing the volume of the connecting means and causing expulsion of fluid from the connecting means through the second one-way valve to the reservoir. Expulsion of the fluid may occur on either the rise or fall ofthe liquid level in the reservoir. The reservoir suitably is a W.C. cistern. |
