Flow Regulator

Flow regulator (10) comprising a regulator housing (1) having a passage channel (2) in which there are two control devices (8a, 8b) each having a central body (3a), surrounded by an annular throttle body (4a) made from elastic material, wherein the throttle body (4a) bounds a control gap (6a) between itself and an adjacent peripheral surface (5a) provided with control recesses (7a), which are spaced apart from each in a circumferential direction and which are oriented in a flow direction (Pf1, Pf2), a passage cross section of the control gap can be changed by the throttle body (4a) deforming under a pressure difference formed by a flow, the two control devices (8a, 8b) are arranged one behind the other in a longitudinal extent of the passage channel (2), the two control devices (8a, 8b) are constructed for at least one of different flow rates or different pressure ranges, and a first of the control devices (8b) has at least one bypass channel or a passage opening (11) for at least one of a lower flow rate or a lower pressure range, and the passage opening (11) can be opened and closed, and is opened for a higher flow rate or a higher pressure range and is closed for the lower flow rate or the lower pressure range.
