Abstract:
A flow regulator comprising a flow dispersion device (9) which divides water flowing through the flow dispersion device (9) into several separate water streams and a flow regulation device (1) that forms a face of the flow regulator on an outlet side and is connected downstream in a flow direction and has a perforated plate (2) on the outlet side constructed as a perforated field of a planar surface that is oriented transversely to the flow direction, the perforated plate (2) has several flow-through holes (3) having a generally hexagonal flow-through cross-section extending over the entire planar surface, the flow-through holes (3) are defined by guide walls (4) that separate adjacent flow-through holes from each other and that extend in approximately the flow direction, each guide wail has a wall thickness (s) which amounts to a fraction of an internal cross-sectional width (w) of one of the flow-through holes (3) defined by the guide walls (4), the flow dispersion device (9) and the flow regulation device (1) being arranged in a flow regulator housing of the flow regulator, a ratio h to D between a height (h) of the guide walls (4) and a total diameter (D) of the flow regulation device (1) is smaller than 3 to 21, and on the flow outlet side of the flow regulator housing downstream of the flow regulation device (1), a housing constriction (23) for stream narrowing is provided.
