The invention relates to a flow-volume regulator (1, 110) having a regulator housing (2) which (2) has at least one regulator ring channel (3) which (3) contains an annular flow restrictor (4) made of elastic material which (4) bounds, between itself and a channel wall that bears a regulatory profiling (5), a control gap (6) for which (6) it is possible to alter the passage cross section by means of the flow restrictor (4), which deforms under the pressure difference that forms during the flow, and also having at least one valve (7) which has a valve body (8) which (8) moves under the pressure of the flowing medium from an open position counter to a restoring force into a closed position, in which closed position the valve body (8) closes off at least one valve opening. In order to be able to make the flow-volume regulator according to the invention compact and also to mount it in space-saving fashion under confined circumstances, the invention provides for the valve body (8) to be provided in a valve ring channel (9) in the regulator housing (2) which valve ring channel (9) has at least one valve opening in the region of its channel base, for the valve body (8) to be of annular design and to made from elastic material, and for the annular valve body (8) to deform under the pressure of the flowing medium such that the valve body (8) moves from the open position counter to the restoring force of the inherent elasticity of the elastic material used for the valve body (8) into the closed position. |
