Definitions

  • the invention relates to a jet regulator for a sanitary outlet fitting with an optionally usable jet separator and a housing made of injection-molded plastic, which is connected in one piece to a sieve holding sleeve intended for receiving shaped sieves and in one piece with support stops for the jet separator, air inlet slots being provided between the sieve holding sleeve and the housing are.
  • Such known jet regulators usually have individual parts, some of which are designed to be constant for different areas of application, in particular different flow classes, while in particular the jet splitter can be varied according to the flow class required in each case. This individually required adaptation of the jet regulator to the respective pressure conditions is therefore in conflict with the most rational and standardized possible manufacture of such jet regulators.
  • jet regulators that are largely used are constructed in pieces, but there is the disadvantage that the entire jet regulator must be replaced in order to adapt to a different flow class.
  • jet regulators are already known in which the housing and sieve holding sleeve are produced in one piece by spraying and in which a jet separator plate can be exchanged to adapt to different pressure conditions (see DBGM 19 04 091).
  • these known jet regulators still have disadvantages.
  • a sieve holding sleeve accessible from the outlet side, in which one or more sieves are provided. The sieves are held here by a mouth-side crimping, which takes place only after the sieves have been inserted and requires additional post-processing of the injection molded part. This subsequent crimping does not always result in the desired secure mounting.
  • the forming screens and the jet separator can be inserted into the housing from the inlet side and can be fixed against supports from the inlet side.
  • the usability of the forming sieve and jet separator from the inlet side simplifies the manufacturing process of the jet regulator in essential points.
  • the housing and the sieve holding sleeve can be injection molded in one piece into their final shape and the forming sieves and the jet separator can be assembled from the same side. Damage to the surface of the housing by introducing the sieve holding sleeve is excluded because this operation by injection z. B. a stop collar is avoided.
  • the holding sleeve has a radially inwardly drawn support collar or the like.
  • the forming screens can not only be used from the inlet side, but can also be removed from the housing if necessary.
  • it promotes easy demolding of the housing or the holding sleeve from the injection mold.
  • the screen holding sleeve is expediently connected to the housing by holding webs designed as longitudinal ribs, so that the air between the individual longitudinal ribs is formed axially running air inlet slots can be sucked. It is advantageous if the longitudinal ribs, which are expediently evenly distributed over the circumference of the screen holding sleeve, preferably extend in the axial direction beyond the outer jacket of the holding sleeve and each have a step which increases the clear diameter as a support stop for the jet splitter in the feed direction.
  • the rib inner surfaces continuing behind the steps in the direction of the inlet expediently form the guide surfaces for the jet splitter that can be used on the inlet side.
  • the jet splitter is thus fixed both in the discharge direction and laterally to the discharge direction, without the need to postprocess the injection-molded housing or holding part.
  • the inner ends of the longitudinal ribs which are preferably approximately aligned with the outer region of the inlet side of the jet separator, expediently serve as a support for a sealing ring. This also seals the edge-side, distributed over the circumference of the housing between the longitudinal ribs against the ingress of water from the outlet fitting, so that the water entering the jet regulator cannot flow past the jet splitter through these spaces.
  • the sealing ring which is expediently applied inward via the outer region of the inlet side of the jet splitter, acts on the jet splitter in the direction of its support stops, because the sealing ring is pressed onto the fin ends and the jet splitter by the mouth edge of the outlet fitting associated in the individual case.
  • the simultaneous sealing of the longitudinal rib space and the application of the jet splitter is achieved in that the inlet-side outer area of the Jet splitter, for example, is aligned with the inner ends of the longitudinal ribs, which also largely prevents the sealing ring from partially bending into the longitudinal rib spaces.
  • the or the forming sieves are also fixed in a simple manner in that the jet separator has a support mandrel or the like on its outlet side, which acts on the forming sieve (s) on its inlet side.
  • the jet separator has a support mandrel or the like on its outlet side, which acts on the forming sieve (s) on its inlet side.
  • the housing with the screen holding sleeve has a color coating, for. B. has a chrome plating, painting or pulverization, or consists of colored plastic, which is made possible in a clean design by avoiding the subsequent flanging.
  • a jet regulator 1 can be connected to a sanitary outlet fitting 2, of which a part of the connection end can be seen in FIG. 1.
  • the jet regulator 1 essentially has a housing 3 with built-in parts therein, in particular a jet splitter 4 and shaped sieves 5.
  • the forming screens 5 are stored in a screen holding sleeve 6, 7 air inlet slots 8 being provided between the latter and the housing 3 in the mouth region 7.
  • the jet regulator 1 as a whole and thus also the built-in parts are mass-produced articles which should be able to be manufactured and assembled with as little effort as possible. At the same time, however, there should be the possibility of being able to use the built-in parts in different designs and / or numbers during assembly in the housing 3, in order thereby to make an adjustment while the other parts are otherwise the same to meet different requirements, especially with regard to the flow class.
  • the housing 3 and the sieve holding sleeve 6 located therein are made in one piece from injection-molded plastic, so that these two parts can be produced in a single operation. They are then consistently available for different designs by correspondingly different equipment with the respective built-in parts. It is essential that the assembly of the differently designed built-in parts can be carried out easily and without reworking the housing 3.
  • the holding sleeve 6 on the mouth side has a radially inwardly drawn-in support collar 9 for the forming screens 5, the clear receiving cross-section d for the forming screens being designed to be approximately constant to the end open at the rear.
  • the shaped screens can thus be inserted from the inlet side 10 and then rest against the support collar 9 on the mouth side.
  • the holding sleeve 6 is in the peripheral region via rib sections 11 (Fig. 2 u.3) of longitudinal ribs 11 connected to the housing 3. These continue beyond the outer jacket of the screen holding sleeve 6 in the axial direction, abutting the inside of the housing wall and connected to it in one piece.
  • the longitudinal ribs 11, at a certain axial distance from the screen holding sleeve 6, have a step that increases the clear diameter of the housing 3 as support stops 13 for the jet splitter 4.
  • the cross section of the housing 3 thus enlarged by the support stops 13 in the direction of the inlet is adapted to the diameter of the jet splitter 4.
  • One of the pads Stops 13 located in the direction of the inlet end 10 rib area 11 'thus serves as a guide for inserting the jet splitter 4 from the inlet side.
  • the ends 14 of the longitudinal ribs 11 on the inlet side 10 serve as supports for a sealing ring 15, which at the same time also covers an outer ring region of the rear of the jet regulator 4.
  • the jet splitter 4 is held axially in both directions in the installed position, on the one hand by the support stops 13 and on the other hand by the sealing ring 15 and centered in the radial direction by the ribs 11.
  • the forming screens 5 are held down against the support collar 9 by means of a pin 16 on the jet separator 4.
  • the length of the pin 16 is adapted to the number of forming sieves 5 and their position.
  • Air intake windows 12 are provided at the outlet-side edge of the jet separator 4 on the support stops 13 and between the longitudinal ribs 11 continuing towards the mouth and the inlet-side edge of the outer casing of the screen holding sleeve 6. Thus, air can be sucked in through the air inlet slots 8 in the peripheral region of the mouth between the longitudinal ribs 11 and then through the air intake windows 12 into the area of the water jet passing through.
  • the housing 3 can, for. B. with an external thread (see. Fig. 3) or with an internal thread (see. Fig. 2) or in comparable ways at the mouth of the outlet fitting.
  • the only decisive factor here is that the sealing ring 15 is held in place by the type of fastening at the mouth of the outlet fitting, so that the jet disassembler 4 and forming sieves 5 are also fixed in the housing 3 in the axial direction.
  • the housing 3 with the screen holding sleeve 6 is made of plastic, which has a chrome plating, a color coating, e.g. has a paint or other coloring powder. Because the housing 3 has already received its final shape after the injection molding process and post-processing, in particular heating the housing at its mouth area for crimping the forming screens 5, the final coloring of the plastic can take place simultaneously with the injection molding process. Any after-treatment to eliminate "optical" damage caused by the subsequent crimping is not necessary.
  • the jet regulator according to the invention is thus efficient, of good quality and also particularly inexpensive to produce as a mass article.
