Definitions

  • the invention relates to a flow rate regulator for an air duct of an air conditioning system, in the rectangular in a housing cross-section in the at the shorter Rectangular sides of the housing walls a flap on a near the Cross-sectional central axis arranged axis is mounted, which is close to the axis is angled and by at least one spring element against that of the flow force applied to them in a flow cross-section more or less occlusive Position is held, with her one leg in the open position in essentially parallel to the pipe axis in the flow direction to the rear and her other leg in the closed position substantially perpendicular to the pipe axis is aligned.
  • Such a flow regulator is known through use.
  • the invention is based on the object, the shape and dimensional accuracy of To improve the housing of such a flow rate regulator.
  • this purpose is fulfilled by that on the longer Rectangular sides lying housing walls by multiple flat edging in the Flow cross-section are indented.
  • the bends give the housing walls rigidity and dimensional accuracy. This ensures that the adaptation of the spring element or the spring elements to the applied for Einregelung certain flow rates forces is not invalidated by inaccurate arrangement of the spring elements on a warped sheet metal wall. In addition, then remain at largely closed flap narrow passage gaps still have an exact shape and width.
  • the indentations are also advantageous in that they increase the flow velocity at the location of the flap, thus improving the response of the flap, at least in the areas of lower preshrubs. Also, by increasing the flow velocity, the cross-sectional profile of the flow is made uniform.
  • a central portion of the indented housing walls is parallel to the housing axis and the flap is disposed between the parallel portions of the two opposite housing walls, wherein preferably the middle portion each between a shorter, oblique portion and a longer, less oblique portion of the housing wall is located, and the shorter, more oblique portion of the housing wall on the side of the open position obliquely forward flap leg front and on the side of the rearward flap leg is located behind.
  • each flap leg can interact with a housing wall section parallel to the flow direction.
  • the two parallel sections overlap.
  • the same sheet metal part can be used in relation to the flow direction, the reverse arrangement.
  • the reduction of the flow cross section through the indentations is, for example, 10 to 15%, preferably 12 to 13%.
  • the flow rate regulator consists essentially of one in a housing. 1 arranged flap 2, which by spring force in a flow cross-section more or less occlusive position is held.
  • the housing 1 is composed of two flat housing walls 4 and two double flat folded housing walls 5 together. All housing walls 4 and 5 are angled at the input and the output of the flow rate controller to a circumferential flange 6. With the two flanges 6, the flow regulator is to be inserted into an air duct of the same rectangular cross section.
  • the bent housing walls are each divided into a shorter oblique section 7, a parallel to the axis of the flow controller section 8 and a longer oblique section 9. With each at a portion 7,8 or 9 angled sheet metal sections 10,11 and 12, between which narrow column 13 remain, the housing walls 5 abut the housing walls 4. Rivets 14 brought them together.
  • the flap 2 is mounted on the housing walls 4.
  • She has an angular shape Cross-section. In the angle is its axis 15, which pierces the housing walls 4 and in mounted on the outside of the housing walls 4 bearings 16 ends.
  • a respective tension spring 21 and 22 mounted, which has a holder as follows: On the one housing wall 5 sits a nozzle 23 and on this a transparent plastic sleeve 25. In the plastic sleeve 25 protrudes one end of a rod 28, whose position with respect to the housing wall 5, further or less far pulled out, arranged in the sleeve means can be fixed. At the other, projecting into the flow cross-section end of the rod 28, the tension spring 21 and 22 is attached via a hinge part 33.
  • the right in Fig. 2 tension spring 22 has a steeper spring characteristic than the left tension spring 21. It remains inactive for smaller strictlyregelnde flow rates.
  • the transparent plastic sleeves 25 are provided with a, drawn out in Fig. 2, Scale provided on the basis of which the desiredstruregelnde flow rate by appropriate adjustment of the brackets and thus bias of the tension springs 21,22 can be adjusted.
  • the flap 2 is due to their angulation and stabilization of this angulation by the Sheet metal discs 18 highly torsion resistant.
  • the asymmetrical introduction of force solely by the tension spring 21 or stronger by the tension spring 22 is readily available possible.
  • the axis 15 can be dimensioned correspondingly weak.
  • Fig. 1 shows the flap 2 in the closed position, i. at the lowest set flow rate and highest form.
  • the open position i. the other End position
  • the rearward leg 50 of the flap 2 is located on the consoles 37 and the other leg 51 is obliquely forward. Because in every position the flap 2 of the legs 51 is more strongly flowed than the leg 50 searches the flow the flap 2 against the force of the spring elements, i. the tension springs 21 and 22, close.
