Publication number: 20050247805Abstract: The invention concerns a sanitary component (1) that has a jet regulating device (4) in the interior of a mounting housing (6). The jet regulating device (4) includes at least one directly-mounted element (5) housed in the mounting housing (6), this element being provided with ridges (11) transverse to the flow direction and defining between them passageways (12). The invention is characterized in that the ridges (11) of at least one directly mounted element (5) are arranged in the form of a grid or network and intersect at junction points. The component (1) according to the invention, which can be manufactured inexpensively, exhibits the best possible jet regulating characteristics, even if the transverse surface is relatively small; moreover, the component (1) according to the invention requires little maintenance, without any risk of malfunction resulting from dirt carried by the liquid flow.Type: ApplicationFiled: September 26, 2003Publication date: November 10, 2005Applicant: Neoperl GmbHInventor: Hermann Grether
