Definitions

  • the invention relates to a jet regulator having a jet regulator housing which has a housing part with a sleeve-shaped housing wall, which housing part, in the sleeve interior thereof, is integrally connected to a jet fractionater which is oriented transversely with respect to the direction of flow and has a plurality of flow-through openings for dividing the incoming water flow into a plurality of individual jets.
  • Jet regulators are already known in different designs. Such jet regulators are mounted on the outlet end of a sanitary outlet fitting in order to generate a homogeneous, non-spraying and, where applicable, also bubbling soft water jet.
  • a jet regulator of the aforementioned type which has a jet regulator housing with an upstream first housing part and a downstream second housing part is already known.
  • the housing parts which can be releasably connected together, have a sleeve-shaped housing wall.
  • the upstream first housing part is integrally connected in the sleeve interior thereof to a jet fractionater which is oriented transversely with respect to the direction of flow and has a plurality of flow-through openings which are to divide the incoming water stream into a corresponding plurality of individual jets.
  • An attachment screen which is to hold back the particles of dirt possibly entrained by the water before said particles of dirt could otherwise lead to operation-impairing deposits in the interior of the jet regulator, is releasably held in the upstream part region of the sleeve interior which is divided off from the jet fractionater and slightly protrudes over the jet fractionater plane.
  • the previously known jet regulator is insertable as far as up to an annular flange, which protrudes on the outside of the first housing part, into an outlet mouth piece which can be releasably mounted by means of a screw connection at the outlet end of a sanitary outlet fitting.
  • jet regulators which, on the outer circumference of the jet regulator housings thereof, carry an external thread which can be screwed into an internal thread on the inner circumference of the outlet fitting in such a manner that the jet regulator is arranged almost completely in the outlet end of the sanitary outlet fitting, have also been created.
  • the jet regulator as claimed in the invention has a single-part or multi-part jet regulator housing with at least one housing part.
  • the at least one housing part which has a sleeve-shaped housing wall, is, in the sleeve interior thereof, integrally connected to a jet fractionater which is oriented transversely with respect to the direction of flow and which has a plurality of through-flow openings which divide the incoming water stream into a plurality of individual jets.
  • An external thread is provided on the outside circumference of the portion of the housing wall defining the upstream part region of the sleeve interior, by way of which external thread, the jet regulator as claimed in the invention can be releasably fastened on an internal thread which is provided on the inner circumference of the outlet fitting. Said external thread is provided in a portion of the jet regulator housing which can be developed in a comparatively thin-walled manner.
  • an attachment screen and/or a flow regulator is held in particular so as to be releasable in the upstream part region of the sleeve interior which is divided up by the jet fractionater.
  • a preferred further development as claimed in the invention provides that the upstream part region of the sleeve interior is dimensioned for the complete accommodation of the attachment screen and/or of the flow regulator in such a manner that the upstream end circumferential edge of the jet regulator housing forms the upstream closure of the unit including the jet regulator and attachment screen and/or flow regulator.
  • the external thread can be arranged in a portion of the housing wall protruding upstream over the jet fractionater.
  • the jet regulator has at least one axial and/or at least one radial annular seal for sealing the space provided between the jet regulator outer circumference and the inner circumference of a sanitary outlet fitting. So that the space remaining between the jet regulator outer circumference and the inner circumference of the outlet fitting is unable to allow through any unwanted leakage flows to impair the jet pattern, at least one axial and/or at least one radial annular seal is provided.
  • At least one groove for the accommodation of a preferably radially effective sealing ring is arranged on the outer circumference of the regulator housing.
  • a sealing ring which seals between the jet regulator and an annular shoulder provided on the inner circumference of a sanitary outlet fitting, is provided for axial sealing.
  • Another design as claimed in the invention provides that the axially effective sealing ring rests on the upstream end circumferential edge of the jet regulator. Instead of this, however, it can also be expedient when the axially effective sealing ring is supported in the upstream sleeve interior and projects over the upstream end circumferential edge of the jet regulator housing.
  • housing moldings which serve as tool contact surfaces for a rotary tool, are provided preferably spaced apart from each other in a regular manner on the outer circumference of the jet regulator housing.

  • a sealing ring 18 or 19 which seals between the jet regulator 1 and an annular shoulder 20 provided on the inner circumference of the sanitary outlet fitting 3 , is provided for axial sealing.
  • an annular shoulder is missing in the case of the outlet fitting 3 shown in FIGS. 9 to 11
  • the jet regulator shown in FIGS. 7 to 13 relies on a radial seal.
  • the axially effective sealing ring 18 rests on the upstream end circumferential edge 13 of the jet regulator housing 4 and is clamped between the end circumferential edge 13 and the annular shoulder 20 .

  • housing moldings 22 which are spaced apart from each other in a regular manner and serve as tool contact faces for the rotary tool 21 , are provided on the outer circumference of the jet regulator housing 4 .
  • the rotary tool 21 which has a sleeve-shaped part region, has, on the end edge region of said sleeve-shaped part region or on the inner circumference, recesses 23 into which the housing moldings 22 , which frame the aeration openings 31 in the jet regulator housing 4 and in particular in the housing part 6 thereof, (and into which the housing moldings 22 ) can engage during the rotating of the jet regulator 1 .
  • the housing parts 5 , 6 are connected together in a non-rotatable manner. It is true that a non-rotatable connection of this type can also be achieved by welding the housing parts 5 , 6 ,—however, the embodiment shown in more detail in FIGS. 12 and 13 is preferred where the housing parts 5 , 6 are certainly connected together in a non-rotatable manner, but are nevertheless releasable.
