Flow regulator
First Claim
1. 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.

Abstract
The invention involves a flow regulator (80) with a flow dispersion device (9) as well as with a flow regulation device (1) that forms the face of the flow regulator (80) which is connected downstream in the flow direction and has several flow-through holes (3). For the flow regulator according to the invention it is characteristic that the flow regulation device (1) has a perforated plate (2) on the outlet side, that has, in at least a partial area constructed as the perforated field of its planar surface that is oriented transversely to the flow direction, several flow-through holes (3) whose guide walls (4) that separate adjacent flow-through holes from each other and extend in approximately the flow direction. Each guide all has a wall thickness that amounts to a fraction of the internal hole diameter of a flow-through hole (3) limited by the guide walls (4), and that the ratio h to D between the height (h) of the guide walls and the overall diameter (D) of the flow regulation device is smaller than 1. The flow regulator according to the invention is characterized by an especially good flow formation and a high functional reliability, is where this flow regulator can be manufactured at a comparatively small expense (see FIG. 6).
