Definitions

  • the invention relates to a jet regulator with a jet regulator housing that can be used in a sanitary outlet fitting and with at least one seal that runs around the jet regulator housing and seals between the jet regulator housing on the one hand and the outlet fitting on the other.
  • Flow regulators of the type mentioned at the outset are already known in various designs. Such jet regulators are regularly inserted into an outlet mouthpiece which is detachably held on a sanitary outlet fitting. Using such aerator a homogeneous, soft and non-splashing water jet to 'be formed.
  • the seal used in these jet regulators is usually a separate sealing ring made of rubber or a similarly flexible material that is used between the jet regulator housing and the outlet fitting.
  • the sealing ring When the jet regulator is attached to the outlet fitting, the sealing ring is compressed and thus seals the gap between the jet regulator housing and the outlet fitting.
  • the disadvantage here is that 'the sealing ring can easily be lost as a relatively small component and that the onset of the jet regulator with top hook seal without the seal while leaving its optimal position is difficult and requires craftsmanship.
  • the jet regulator has an upstream component which extends over the clear outlet cross section and which is connected in one piece to at least one seal between the jet regulator housing and outlet fitting.
  • the upstream component with the seal integrally connected to it extends as a single component over the clear cross section and thereby prevents creeping or leakage currents of the liquid flowing through the jet regulator between the jet regulator housing and the outlet fitting and between the jet regulator housing and the insert parts of the jet regulator ,
  • the upstream component is a housing part with a molded beam splitting device. Since the jet cutting device is integrally formed on the upstream housing part, a separately usable jet cutting device is avoided. In addition, the jet separation device molded onto the housing part is considerably more stable and tends to be less prone to noise-causing natural vibrations than is the case with previously known jet regulators. Due to the jet splitter device which is integrally formed on the inflow-side component and the seal which is also integrally connected to it, a better tolerance tolerance of the entire jet regulator can be achieved, since there is less dimensional addition of tolerances of individual parts.
  • the upstream end edge region of the housing part is designed as a sealing profile.
  • a jet regulator housing designed in this way can also be designed with a comparatively wide front edge without the clear outer cross section is restricted too much. This comparatively wide end edge on the jet regulator housing can then be used very well to design a comparatively complex sealing profile.
  • the sealing profile has at least one surface seal and / or a lip seal.
  • These forms of the sealing profile together with the counter stop of the outlet fitting can provide an effective seal if the sealing profile acts on the counter stop and a line and / or surface pressure is exerted on the sealing profile.
  • the upstream component has an insertion stop which, in the division of use of the jet regulator, limits deformation of the sealing profile. Otherwise, the sealing profile could be damaged or excessively deformed, which could lead to a leak in the area between the jet regulator housing and the outlet fitting and thus to corresponding leakage currents.
  • the sealing profile has at least one seal with a sealing profile base, which is designed as an insertion stop.
  • the sealing profile can be arranged on the upper boundary surface of the sealing profile base.
  • the insertion stop can serve to limit the screw-in depth when the jet regulator is attached to the fitting, for example via a screw connection. If the screwing in is done manually without tools, the insertion stop can convey a feeling of strength of the screw connection by noticeably the action of the counter stop on the fitting through the insertion stop is.
  • the sealing profile and, if applicable, its insertion stop cooperates with a front edge area of the outlet fitting which limits the clear cross-section and which simultaneously acts on the jet regulator housing serves as a counterstop.
  • the insertion stop is arranged adjacent to the sealing profile in the radial direction. This means that the insertion stop can absorb exactly the forces that could possibly damage the sealing profile.
  • a space-saving arrangement of the insertion stop and the sealing profile can be achieved on the clear cross section of the jet regulator.
  • a simple and yet effective sealing configuration of the sealing profile consists in the sealing profile having at least one annular sealing lip.
  • This sealing lip can either be designed to be elastic and flexible and thus adapt to the counter-stop when the jet regulator is attached to the outlet fitting on the outlet fitting, or the sealing lip is designed in such a way that it is difficult to deform, so that the sealing lip only attaches through surface pressure when fastening seals the counter stop of the outlet fitting.
  • a particularly advantageous embodiment of the sealing profile provides that the sealing profile surrounds at least two rings. running sealing lips, which take effect one after the other with increasing insertion pressure acting on the jet regulator.
  • This graduated configuration of the sealing profile can have the effect that, if one sealing lip fails, the adjacent sealing lips of the sealing profile take effect.
  • an insertion pressure can be exerted on the jet regulator in such a way that at least further seals of the sealing profile can also be effective.
  • a further embodiment with sealing lips running around in a ring and taking effect one after the other provides that these sealing lips have different heights. This makes it possible to maintain the sealing effect for a long time by retightening the outlet mouthpiece screwed to the outlet fitting after long use of the jet regulator. If the highest sealing lip is already somewhat damaged or worn or inflexible, the sealing lip closest in height can achieve the sealing effect again after tightening. In addition, small unevenness in the counter stop of the outlet fitting can be compensated for. It can be advantageous if the sealing lips have stepped heights and if the highest sealing lip forms the innermost or outermost seal of the sealing profile.
  • At least the upstream component is manufactured as a multi-component injection molded part and that the component consists of a flexible and / or elastic material in the region of the at least one seal.
  • the upstream component and at least one seal connected to it in one piece are made from the same, preferably food-safe material are. This simplifies the manufacturing effort and the tool costs for any injection molding tool that may be required are kept comparatively low.
  • FIG. 1 is a partially sectioned illustration of a jet regulator with a single sealing lip and a radially adjacent insertion stop
  • FIG. 2 is a partially sectioned illustration of a jet regulator with a single sealing lip
  • FIG. 3 shows a partially sectioned illustration of a jet regulator with a surface seal as a sealing profile
  • FIG. 4 shows a partially sectioned illustration of a jet regulator with two radially adjacent sealing lips with an oppositely directed bevel
  • Fig. 5 is a partially sectioned view of a jet regulator with two radially adjacent sealing lips with bevels in the same direction and
  • Fig. 6 is a partially sectioned representation of a jet regulator with four radially adjacent, annular circumferential sealing lips.
  • a jet regulator designated as a whole by 1, has a circumferential seal on the jet regulator housing 2, which seal is located between the jet regulator housing 2 on the one hand and the outlet fitting. on the other hand seals, the seal being connected in one piece to an inflow-side component which extends over the clear outlet cross section of the jet regulator 1.
  • the jet regulator housing is designed in one piece. 1 to 6, however, it can be seen that the jet regulator housing 2 is designed in several parts here and that the upstream component is an upstream housing part 4 with a molded jet splitting device 5.
  • the upstream end edge region of the housing part 4 is designed as a sealing profile 6 and the jet cutting device 5 as a perforated plate.
  • the housing part 4 of the jet regulator 1 shown in FIG. 1 has a sealing lip 6b as a sealing profile 6 and an outer insertion stop 7 running in parallel therewith, the insertion stop 7 limiting a deformation of the sealing profile 6 in the position of use of the jet regulator 1.
  • the sealing profile 6 cooperates with the sealing lip 6b and its insertion stop 7 cooperates with a front edge region of the outlet fitting which limits the clear outlet cross section.
  • FIG. 3 shows an embodiment as a single sealing lip 6 on a sealing profile base 6a.
  • the sealing profile base 6a is designed as an insertion stop 7 which, in the embodiments of the sealing profile 6 shown in FIGS. 2 and 3, limits the insertion depth of the jet regulator 1 in an outlet mouthpiece 3 into the outlet fitting.
  • FIG. 4 and 5 show two configurations of the sealing profile 6, each with 2 sealing lips 6b, which are circumferentially annular in the upstream end edge region of the housing part 4 are arranged.
  • the flanks of the sealing lips 6b are chamfered differently in order to influence the deformation in the position of use.
  • the opposing oblique flanks shown in FIG. 4 cause the sealing lips 6b to bend apart in the position of use of the jet regulator 1 and thus also to seal a wide end edge region of the outlet fitting.
  • 5 shows two sealing lips 6b, which each have bevels on their outside and are thereby bent toward the center of the jet regulator 1 in the use position of the jet regulator 1.
  • FIG. 6 shows an advantageous embodiment of the sealing profile 6, wherein sealing lips 6b are provided on the sealing profile base 6a, which encircle each other in an annular manner and become effective one after the other, which are arranged stepwise to one another and have differently graduated heights. These sealing lips 6b become effective one after the other as the insertion pressure acting on the jet regulator 1 increases. This makes it possible, after prolonged use of the jet regulator 1, to maintain the sealing effect for a long time by retightening the outlet mouthpiece screwed to the outlet fitting. If the highest sealing lip 6b, which is formed here by the radially outermost sealing lip 6b, has already been somewhat damaged or worn or has become inflexible, the sealing lip 6b that comes closest in height can achieve the sealing effect again after tightening. In addition, small unevenness in the counter stop of the outlet fitting can be compensated for.
