Definitions

  • the invention relates to a device for limiting the flow, in particular for the outlet of sanitary water fittings; Water is getting more and more expensive. This is due to the increasing waste and pollution, which means that local authorities have to build ever more complex sewage treatment plants. Saving water is therefore advisable. Apart from changing your own behavior, water consumption in sanitary engineering, e.g. can be reduced by additional valves which can serve as flow restrictors and for shut-off and are easy to attach to the tapping points. Also known are special designs of aerators as flow restrictors.
  • the invention has for its object to eliminate this disadvantage and to provide a device for limiting the flow of the type mentioned, which is very simple in construction, cheap to manufacture, safe in function and very easy to install later.
  • a flow restrictor which is arched against the direction of flow and is formed by a one-piece molded part which has a passage opening and is provided with at least one preformed breaking point to enlarge the passage opening.
  • This flow restrictor is installed between the end of the outlet of the sanitary water fitting and an air sprinkler or a jet regulator. Further refinements of the Invention are characterized in the subclaims.
  • FIG. 1 shows an exploded view of a pivotable pipe outlet of a washbasin mixer with an aerator, a sealing ring and a flow restrictor according to the invention
  • FIG. 2 shows the flow restrictor in plan view
  • FIG. 3 shows the flow restrictor in FIG The bottom view
  • Figure 4 shows the flow restrictor in cross section.
  • Fig. 1 denotes the pipe outlet and 6 the aerator.
  • the flow restrictor 7 consists of a one-piece molded part made of plastic, it has a central passage opening 8 and is surrounded by a sealing ring 10 provided between the end 9 of the pipe outlet 5 and the aerator 6.
  • the flow restrictor 7 has a ribbing 11 on the outside for a clamping connection with the sealing ring 10 in the preassembled state.
  • the flow restrictor 7 has a break 12 for the desired enlargement of the passage opening 8. In this way, the flow can be 7.5 l / min or 9 l / min at 3 bar. If the flow restrictor 7 ceases, the major flow is 12 l / min.
  • the flow restrictor 7 has a curvature 13 against the direction of flow. A corresponding curvature has on the first sieve 14 of the aerator 6, so that the flow restrictor 7 in its arched region 13 runs parallel or approximately parallel and at a distance from the first sieve 14 of the aerator 6, which is arched in a manner known per se against the direction of flow. The distance is preferably 1 to 3 mm.
  • the embodiment shown and described is only an example for realizing the invention and this is not restricted to this. Rather, there are other design and application options within the framework of the inventive concept.
  • the flow restrictor can also consist of a one-piece elastomeric plastic part, whereby the sealing ring 10 could be omitted.
  • the flow restrictor would also function as a flow stabilizer of limited shape at differential pressures.
  • the flow restrictor could e.g. be installed between the end of the outlet and a shower hose or two of these and a shower head.
