ABSTRACT:
The invention provides a device for the metered passage of a liquid, comprising a container for the liquid, which is provided with an inlet and an outlet for supplying liquid to and discharging liquid from the container, respectively, and with a bottom and upright side walls joining said bottom. The device furthermore comprises means for regulating the extent to which liquid is supplied to the container via the inlet in dependence on the amount of liquid that is present in the container. The metering means comprise a floating element which floats on the liquid in the container and which is rigidly connected to an overflow edge that can move up and down together with the floating element between a lowermost position and an uppermost position, over which overflow edge the liquid flows into the container at the location of the inlet. The overflow edge forms part of at least one side wall of the container.
