  • Publication number: 20050247805
    Abstract: 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.

  • Patent number: 6902123
    Abstract: The invention relates to a sanitary fitting (5) including an external housing (2) that has at least one housing section (6, 7, 30), the housing section (6, 7, 30) having an insertion opening (10) on an inlet side. At least one functional unit can be inserted through said opening into the interior of the housing until it abuts an insertion stop (18, 19, 29). A housing clearance (20, 21, 22) for receiving the protruding part of the functional unit(s) that projects beyond the insertion stop is located upstream and/or downstream of the insertion stop (18, 19, 29) in the direction of insertion.

  • Patent number: 6892964
    Abstract: The invention relates to a jet regulator (1), comprising a jet regulator housing (2), within the interior of which a jet regulation device (4) is provided. According to the invention, such a jet regulator (1) can be produced at low cost, by means of simple conventional production techniques with simultaneous anti-scaling effect on the jet regulation device (4), whereby the jet regulation device (4) comprises several insertable components (9, 10), which may be inserted in series in the jet regulator housing (2) in the direction of flow (Pf1). The insertable components (9, 10) comprise passage openings (11), which are unidirectionally defined and extend across the cross-section of the passage, and the passage openings (11) of adjacent insertable components (9, 10) are arranged offset to each other in the circumferential direction of the jet regulator housing (2), or in the direction of flow (Pf1) of the jet regulator (1).

  • Patent number: 6126093
    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.

  • Patent number: 5495985
    Abstract: Jet regulator and aerator for attachment to a faucet contains a circular perforated plate for producing individual jets, and a coaxial sleeve downstream. The sleeve supports--deflection slopes which are inclined at an angle to the flow direction. The deflection slopes may be in the form of conical-pointed pins aimed at the plate. The pins are mounted on a tiered-wedding-cake shaped wall. An axial cone in the sleeve may also comprise a deflection slope. Additional obstacles consist of pins and/or ribs located at intervals from each other.
