Stream former for use as sanitary component in water outlet, has flow guide with edge areas having larger flow cross section relative to longitudinal middle area, where areas extend in both sides of guide in longitudinally extending manner

摘要

The former (1) has a homogenizing device with a set of passage holes that are limited by a flow guiding wall, where the former has a larger stream width compared to stream depth (t) for producing a flat water flow volume. A flow guide (6) is provided upstream or downstream and narrows in a partial area in a flow direction. The flow guide has edge areas (7, 8) with a larger flow cross section relative to a longitudinal middle area (9), where the edge areas extend in both sides of the guide in a longitudinally extending manner.
