Definitions
- the invention relates to a jet regulator with an outlet structure which has an outlet grille with a regular arrangement of holes and an edge which delimits the outlet grille, holes in the outlet structure which are adjacent to the edge form a ring and one through the outlet structure Limit the flowing water jet to the outside, wherein the ring is designed differently from the regular arrangement.
- jet regulators are known and are now manufactured from plastic using injection molding technology. It has become customary here to provide the outlet structure with a regular arrangement of holes, for example a hexagonal arrangement of hexagonal holes, in order to uniformly shape the spray pattern.
- This regular arrangement finds its limit in the dimensions of the jet regulator, which can, for example, have a round or rectangular or some other outer contour deviating from the arrangement.
- the arrangement of the holes and a clear opening cross-section of the holes are matched to one another in such a way that individual jets that pass through the holes recombine behind the outlet structure to form a common water jet.
- the invention is based on the object of improving the jet pattern of such a jet regulator.
- the ring can thus be defined as a collection of all those holes in the arrangement which is continued over the edge and which are trimmed by the edge.
- the regular arrangement of holes of the same size and / or the same shape is formed.
- a regular arrangement and the deviations from such an arrangement can thus be easily recognized.
- the ring is designed differently from the regular arrangement in that the edge trims individual holes in the ring. It is therefore possible to dispense with coordinating the arrangement with the geometry of the edge.
- the enlarged hole of the ring is enlarged at the expense of at least one adjacent hole.
- the adjacent hole can be in the ring.
- a size difference between holes within the ring can thus be compensated for.
- the adjacent hole is in the interior of the outlet structure. This means that holes that are too small can be moved inwards, where they do not interfere.
- each hole in the ring is enlarged in a manner deviating from the regular arrangement, if its clear opening cross-section would otherwise be less than half as large as a clear opening cross-section of an adjacent hole if the regular arrangement was continued.
- the advantage here is that the formation of interference rays can be reduced or even avoided along an entire circumference of the ring.
- the jet regulator can be designed as a ventilated or unventilated jet regulator.
- the outlet structure can, for example, have a round, oval, polygonal, in particular rectangular or square, outer contour.
- a hole in the ring is enlarged, deviating from the regular arrangement, if its clear opening cross-section otherwise when the regular arrangement is continued from the clear opening cross-section of the adjacent hole deviates by more than 20%. It has been found that such small holes are particularly conducive to the formation of interference rays.
- the hole of the ring is enlarged in deviation from the regular arrangement, if its clear opening cross-section otherwise deviates by more than 15% from the clear opening cross-section of the adjacent hole when the regular arrangement is continued.
- a distribution of opening cross-sections within the ring that is as uniform as possible can thus be achieved. This favors a particularly uniform design of an outer layer of the water jet and thus a particularly uniform jet pattern.
- the holes of the ring have clear opening cross-sections which are at most 50% above the clear opening cross-section of a hole in the interior of the outlet structure.
- the holes in the interior of the outlet structure can therefore be used as reference values. The advantage here is that the formation of holes that are too large in the ring can be avoided.
- the holes of the ring have clear opening cross-sections that are at most 20%, in particular at most 15%, over the clear opening cross-section of a hole in the interior of the
- the holes of the ring have clear opening cross-sections that are on or below the clear opening cross-section of a hole in the interior of the Run-out structure. A particularly uniform external view of the exiting jet can thus be achieved.
- the mentioned area proportions can be related to any hole, for example a median or mean value of the opening cross-sections, in the interior of the outlet structure.
- the surface fractions are preferably related to the largest hole or an uncut hole (that is to say, for example, one of the identical holes from which the arrangement is composed) in the interior of the outlet structure. A natural upper limit can thus be defined.
- the clear opening cross-sections of the holes in the ring vary by a maximum of 15%.
- the partial beams, from which one, for example the already mentioned, outer layer of the beam is composed can be defined as equally large as possible. This enables a spray pattern that is as uniform as possible with as few interference rays as possible.
- the outlet structure has at least one rotational symmetry.
- a rotational symmetry of the outlet structure for example a discrete or continuous rotational symmetry, can be transferred to the ring. This favors a particularly uniform formation of a jet pattern.
- the outlet structure has at least one mirror symmetry.
- a mirror symmetry of the outlet structure for example a plane mirror symmetry, can be transferred to the ring. This favors a particularly uniform formation of a jet pattern.
- the outlet structure has at least one point symmetry.
- a point symmetry of the outlet structure for example a symmetry which the outlet structure transforms into itself by point reflection at a center, can be transferred to the ring. This favors a particularly uniform formation of a jet pattern.
- the outlet structure has a hexagonal arrangement.
- the edge is circular.
- the invention can be used with jet regulators that can be screwed to a fitting by turning.
- the outlet structure has at least one hole in the interior, the clear opening cross section of which is less than 50% of a further hole in the ring and / or in the interior. It has been found that the formation of very small holes in the interior does not interfere with the jet pattern, so that other aspects, for example a pleasing design or the desire for a characteristic marking, can be taken into account.
- this at least one hole can be arranged in the interior of the outlet structure adjacent to the ring. It is thus possible to enlarge a hole in the ring at the expense of a hole in the interior. The arrangement can otherwise remain unchanged.
- the further hole in the ring or in the interior of the outlet structure can be a largest hole. So is a absolute upper limit for the clear opening cross-sections can be specified.
- the further hole in the ring or in the interior of the outlet structure can be an uncut hole.
- a dimensioning can be related to identical holes from which the regular arrangement is composed.
- a particularly slight impairment of the overall appearance of the outlet structure results when the enlarged hole takes up the shape of the arrangement in at least one (edge) section.
- the continuation of the arrangement to the edge can be made possible in that, for example, the holes that form the ring have clear opening cross-sections that differ from one another.
- At least one hole, which lies inside the outlet structure and is adjacent to a hole in the ring, is trimmed through this hole in the ring in such a way that its (remaining) clear opening cross section is smaller than that of the uncut holes of regular arrangement is. In this way, space is created in a simple manner for enlarging a hole in the ring that is too small.
- the invention has recognized that small holes inside, i.e. inside the ring, do not interfere with the jet pattern.
- the at least one hole, which the hole in the ring was enlarged at its expense has an opening cross-section other than zero. Excessive deviations from the regularity of the arrangement can thus be avoided.
- no hole in the ring has a clear opening cross-section which is smaller than one half of a clear opening cross-section of the largest and / or uncut holes of the regular arrangement. In this way, jets that are too thin and / or structures that are too fine in the outlet structure can easily be avoided.
- the hole in the interior is combined with a further hole in the interior to form a larger hole.
- a shape and / or an arrangement of enlarged or trimmed holes maintains / maintain a rotational symmetry of the regular arrangement. A pleasing and / or attractive design can thus be achieved.
- a width of the ring is limited by a largest clear dimension of a largest and / or uncut hole in the arrangement, in particular in the interior.
- a natural scale of the outlet structure can thus be used for dimensioning the width, for example a dimension transverse to the direction of rotation of the ring.
- edge sections in which the holes of the ring are delimited by the edge each have a length that is at least one half of a largest clear dimension of a largest and / or uncut hole in the arrangement, in particular in the interior, to have.
- the length of the edge sections can essentially determine the steel image, because it defines an outer dimension of the outer individual rays. In this way, individual beams that are too small can be avoided.
- edge sections in which the holes of the ring are delimited by the edge differ in length from one another by at most 50%, preferably at most 30%. This results in an external appearance of the exiting jet that is as uniform as possible.
- edge sections in which the holes of the ring are delimited by the edge in their length from a largest clear dimension of a largest and / or uncut hole of the arrangement, in particular inside, by at most 50%, preferably at most 30%, deviate.
- the largest clear dimension is usually selected from a balance between the most efficient possible beam calming and the lowest possible beam disturbance.
- a dimensioning of the holes made for the interior of the beam can be transferred to the ring and thus the outer individual beams.

- FIGS. 5 to 7 it can still be seen, in particular by comparison with the drawn hexagons 24, that the enlarged hole 19 takes up a shape of the regular arrangement 12 in at least one section 29. This even applies to all holes 17, 19, 25 in the ring 18, in particular with the sections 29 each facing the interior 22.
