Abstract
A flow regulator () having a regulator housing () which is provided with a control device () having a central body () in a passage channel (). An annular throttle body () produced from an elastic material bounds the central body () and defines a control gap () between the throttle body () and an adjacent peripheral surface () that is provided with control recesses () that are oriented in a flow direction (Pf, Pf). 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 (), there are two control devices () arranged one behind the other the longitudinal direction of the passage channel (), with the two control devices () being configured for different throughputs and/or pressure ranges. The control device () for the lower throughput or the lower pressure range has at least one bypass channel or similar passage opening () 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.
