Abstract

A jet regulator (1), having a perforated plate (5) arranged therein with throughflow holes (6) extending through the perforated plate for dividing the water flowing therethrough, including a central, non-perforated impingement surface (14) on the perforated plate (5), which non-perforated impingement surface is surrounded by a first annular wall (15), which has passage openings (16) that are oriented in a radial direction and extend through the first annular wall, wherein a respective throughflow hole (6), which extends through the perforated plate (5) and is connected to the respective passage opening (16), is provided on the side of each passage opening (16) arranged in the impingement surface plane. The annular wall (15) is surrounded by an annular ring chamber (29) on the outer circumferential side. A flow regulator (30) or a throttling device (300) is provided in front of the impingement surface (14) in the flow direction of the water, whereby the water consumption is restricted and/or the water flow rate becomes largely independent of the particular water pressure. Furthermore, a second annular wall (33), which has a smaller diameter than the first annular wall and is arranged at a distance from the first annular wall, is provided coaxially and concentrically to the first annular wall (15), which second annular wall has radial passage openings (34) arranged at a distance above the impingement surface (14), through which radial passage openings the water has access to the first annular wall (15) and to the passage openings (16) of the first annular wall and thus to the throughflow holes (6). Through this combination, the water flow rate through the jet regulator becomes practically independent of the water pressure upstream of the jet regulator (1).
