The invention concerns a device for the regulation of a constant outflow from a liquid container, in particular from a rain reservoir, with an outflow opening for the liquid, wherein to the outflow opening is assigned a movable throttle element, which in dependence on the liquid level regulates the outflow of the liquid from the container. According to the invention, it is proposed that a component part (2) that is form-changeable in dependence on the fluid pressure control the throttle element, wherein takes place the stopping-down movement of the throttle element against a restoring force (spring 5). A device of this sort makes possible a regulation of a constant outflow from a fluid container, without requiring for this the use of a float.
