Definitions

  • the invention relates to a jet regulator for faucet mouthpieces which can be inserted into a cylindrical outer housing which can be fastened to the faucet mouthpiece, with a cylindrical housing with air slots arranged in its outer wall, a perforated part arranged above the air slots in the cylindrical housing and at least two below the air slots in the Sieves inserted into the housing, of which the lowest, outward-facing sieve is a relatively coarse sieve.
  • This known jet regulator has two screens in the outlet area, of which the outer one is referred to as a relatively coarse screen, however, mesh sizes are not given in the document. Both sieves are flat and the upper sieve has a flanged edge which is angled downwards at a right angle and with which it rests on the edge of the lower sieve for the purpose of maintaining distance.
  • This known jet regulator is already provided with a perforated plate above the air slots, which divides the water inflow into individual jet jets, but a special device for flow rate limitation or flow rate control is not provided.
  • the two sieves forming the sieve arrangement can be placed directly on top of one another with their edges without the need to flare each individual sieve.
  • Each sieve has a curved surface, the two sieves are joined together to form the lens-like sieve arrangement in such a way that the curvatures of the sieves point away from one another.
  • the production of the individual sieves is very simple, it is only necessary to punch out the individual sieves and to provide them with a curvature in a mold.
  • the screens can be made of metal or plastic, for example, they can have a mesh or a perforated field.
  • optimal water-air mixtures result when the screen arrangement is formed by a coarse and a fine screen, the coarse screen being arranged on the outside and the fine screen on the inside. Even with two coarse sieves, however, there is a sufficiently good jet formation. For the optimal formation of a water-air mixture, it is entirely sufficient if a single lenticular sieve arrangement is provided.
  • the arrangement of the coarse strainer on the outside of the jet regulator according to the invention results in a longer service life due to a delayed calcification of the coarse sieve, since after the water flow has been interrupted by the jet regulator, it firstly retains only small amounts of water and, secondly, it evaporation of the lime deposits that form the adhesion water, lay the larger meshes much more slowly.
  • the sieves can be produced and formed in a particularly cost-effective manner if two sieves with the same curvature are connected in the region of their edges by means of a web and the lens-like sieve arrangement is formed by folding the sieves together.
  • the screens connected by means of the web can simultaneously be produced by a tool, by collapsing the screens in such a way that the edges of the screens come to lie on one another and the curvatures of the screens point away from one another, the screen arrangement is formed.
  • the flow control device advantageously consists of a disc which is arranged on spacer ribs on the perforated component and is of limited flexibility, which is provided with certain recesses for a reduced flow cross section.
  • the spacer ribs are expediently formed as an integral component on the upper side of the perforated part and extend radially from the center to the outside.
  • the recess in the limited flexible disc can advantageously be designed as a central hole. The water entering the housing passes through the central hole into the space between the disc and the perforated part, is divided by the ribs, flows through the perforated part past the air slots to pass through the sieve arrangement.
  • the water flows above the air slots essentially in the middle of the faucet mouthpiece and only reaches the outside in the course of the further flow path.
  • the choice of the hole diameter of the disc makes it possible to change the flow of water through the mouthpiece of the tap.
  • An additional control effect can be achieved by the limited flexible nature of the disk if it is partially pressed into the flow channels between the spacing ribs when the inlet pressure is increased.
  • An outwardly curved sieve in particular a fine sieve, is advantageously inserted into the housing above the perforated part or above the disk.
  • the strainer is used to hold back coarse dirt in the water being pumped.
  • the sieve should be arranged in the housing so that it is easy to remove, clean and reinsert.
  • a jet regulator 1 which has a cylindrical housing 2 with louvers 3.
  • the air slots 3 are located in one plane of the housing 2, a plurality of air slots 3 are arranged distributed over the circumference of the housing 2.
  • the water flows through the housing 2 in the illustration according to FIG. 1 from top to bottom.
  • the housing has an inward circumferential projection 4.
  • a sieve arrangement 5 is held by this attachment 4, which is inserted through the housing 2 from above during assembly.
  • the sieve arrangement 5 consists of two sieves which are arranged in a lens-like manner, i.e. the upper sieve 6 has an upward curvature, the lower sieve 7 has a downward curvature.
  • the circumferential edges of the screens 6 and 7 are supported on one another in the area of the housing 2.
  • the upper sileb 6 is fine-meshed
  • the lower sieve 7 is coarse-meshed.
  • the sieves are made of a metal wire, the wire diameter of the coarse sieve should be about 0.5 mm with a clear mesh size of about 0.8 to 1.5 mm, the diameter of the wire of the fine sieve about 0.15 mm to 0, 20 mm with a mesh size of 0.1 to 0.2 mm.
  • the part 9 On its upper side, the part 9 has five ribs 13, which radiate from the center of the part 9 and on which a disc 14 with a central hole 15 is arranged.
  • the disc 14 lies not only on the ribs 13, but also on a further circumferential projection 16 of the part 9. Above the disc 14 there is a fine sieve 17 which is curved outwards.
