ABSTRACT:
The invention relates to a flow regulator for gaseous or liquid media, comprising a housing (1), a regulating unit (1) which changes its free flow area, depending on the flow pressure of the medium, and further comprising a distributor unit (3) behind the regulating means (2) in the direction of flow. To provide a flow regulator which is still relatively simple in construction yet enables more constant volume limitation to be maintained and is less sensitive to manufacturing tolerances of the individual components, the invention proposes that a disc (4) containing at least one hole (5) be provided between the regulating unit (2) and the distributor unit (3) and be movable to a limited extent in an axial direction at least in the region of the hole.
