The present invention relates to a flow regulating EARLY having an annular diaphragm member made of elastic material (6) (1), the throttle member is in the use position, the diaphragm member and the inner and / or regulating the molding unit positioned outside and defining control gap (8) between (21), the control gap (8) of the flow-cross-section is varied by the throttle member (6) that deforms based on the pressure difference occurring when excessive flow of the liquid It related to those of the format that is as to be. In the flow regulator according to the present invention, the relative position between the aperture and the adjustment shaped section member (6) (21), have come to be varied, a large flow-through cross section than the control gap (8) from a starting position with the, based on the liquid flowing, it adapted to be moved to the use position against the return force. Flow rate adjustment EARLY (1) is in the starting position, so do not give rise relatively little resistance to the liquid flowing, flow rate adjustment EARLY (1) the temporal and / or locally significant pressure difference and slightly is adapted to be used in the area of ​​a pressure occur.
