Flow controls that can be inserted in a liquid-supply line or in the accommodating bore of a plumbing fitting. The controls have an essentially cup-shaped mount with perforations through its bottom and a disk of resilient material fits into the perforations. At least the edge of the side of the disk facing the bottom of the cup has a conical bevel of 1.degree. to 5.degree. to the midplane of the disk and narrow ribs and/or sector-shaped webs that extend out essential radially at a prescribed angle around a prescribed circumferential angle.

[ What is claimed is:] [1.] A flow control insertable into a liquid-supply line or in a bore of a plumbing fitting, comprising: an essentially cup-shaped mount having a bottom with perforations therethrough; a disk of resilient material having one side facing the perforations and another side facing a flow of liquid, wherein the one side of the disk has at least an edge portion facing the bottom of the cup-shaped mount and having a conical bevel of 1.degree. to 5.degree. towards a center of the disk and at least one of narrow ribs and sector-shaped webs that extend essentially radially outwardly at angular spacings and have a specified circumferential angle, whereby the movement of the beveled edge portion of the resilient disk towards and away from the perforations in the bottom of the mount in response to changes in liquid pressure effects a flow control.
