Abstract
A flow-volume regulator includes a regulator housing having at least one regulator ring channel having an elastic annular flow restrictor which bounds, between itself and a channel wall that bearings a regulator profiling, a control gap in which a passage cross section is altered by the flow restrictor, which deforms under the pressure difference that forms during flow, and also includes at least one valve which has a valve body which moves under pressure of flowing medium from an open position into a closed position, in which the valve body closes off at least one valve opening. The flow-volume regulator also includes a valve ring channel in the regulator housing having least one valve opening in the region of its channel base, the valve body is annular and elastic, which deforms under pressure of the flowing medium such that the valve body moves from an open into a closed position.
