A flow regulator ( 10 ) having a regulator housing ( 1 ) which is provided with a control device ( 8 a) having a central body ( 3 a) in a passage channel ( 2 ). An annular throttle body ( 4 a) produced from an elastic material bounds the central body ( 3 a) and defines a control gap ( 6 a) between the throttle body ( 4 a) and an adjacent peripheral surface ( 5 a) that is provided with control recesses ( 7 a) that are oriented in a flow direction (Pf 1 , Pf 2 ). The passage cross-section of the control gap can be varied by the throttle body which is deformed by the pressure difference caused during throughflow. In the present flow regulator ( 10 ), there are two control devices ( 8 a, 8 b) arranged one behind the other the longitudinal direction of the passage channel ( 2 ), with the two control devices ( 8 a , 8 b) being configured for different throughputs and/or pressure ranges. The control device ( 8 b) for the lower throughput or the lower pressure range has at least one bypass channel or similar passage opening ( 11 ) which can be opened and closed , and which is open for the higher throughput or higher pressure range and is closed for the lower throughput or lower pressure range.
