Definitions

  • the invention relates to a flow rate regulator for an air duct of an air conditioner in which in a housing rectangular cross-section in the lying on the shorter sides rectangular housing walls a flap is mounted on a near the cross-sectional central axis arranged axis which is angled near the axis and at least one with the Housing connected spring element is held against the force exerted by the flow force in a flow cross-section more or less occlusive position, with her one leg in the open position substantially parallel to the line axis in the flow direction to the rear and her other leg in the closed position substantially perpendicular to the line axis is aligned.
  • Such a flow regulator is known through use.
  • From the DE 27 58 352 A1 is similar to such a flow regulator controller known in which reduced by a plate with rectangular recesses of the line cross-section and thus the flow velocity is increased at the flap. Due to the higher flow rate, the flap can be better controlled at lower flow rates.
  • a flow control valve is provided, equipped with a device for measuring the flow velocity. This measurement is based on the fact that the flow velocity in a tube changes depending on its cross section, the so-called Venturi effect. To allow such a measurement, the tube of the valve has sections with different sized cross sections. In A flap is arranged at the flow velocity behind the Venturi meter, which is opened or closed depending on the measured flow velocity for controlling the flow.
  • the invention has for its object to increase the accuracy of the adjustment.
  • this purpose is fulfilled in that the housing walls lying on the longer sides of the rectangle are indented into the flow cross section by multiple flat edgings and the spring element is connected to one of these housing walls.
  • the bends give the housing walls rigidity and dimensional accuracy.
  • 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 preshrinks. 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 a housing 2 arranged in a flap 2, which is held by spring force in a flow cross-section more or less occlusive position.
  • 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 entrance and at the outlet of the flow rate regulator 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 hold them together.
  • the flap 2 is mounted on the housing walls 4. It has an angular cross-section. In the angle is its axis 15, which pierces the housing walls 4 and ends in mounted on the outside of the housing walls 4 bearings 16.
  • the transparent plastic sleeves 25 are provided with a, in Fig. 2 drawn out, scale provided by which the desired devisregelnde flow rate can be adjusted by appropriate adjustment of the brackets and thus bias the tension springs 21,22.
  • the flap 2 is due to their angulation and stabilization of this angulation by the metal plates 18 to a large extent torsionally rigid.
  • the asymmetrical introduction of force solely by the tension spring 21 or stronger by the tension spring 22 is readily possible.
  • the axis 15 can be dimensioned correspondingly weak.
  • pneumatic vibration dampers 38 are hinged at 39, the other hand at 40 to the flap 2 are hingedly connected.
  • Fig. 1 shows the flap 2 in the closed position, ie at the lowest set flow rate and highest form.
  • the open position ie the other end position
  • the rearwardly directed leg 50 of the flap 2 abuts the brackets 37 and the other leg 51 is inclined forward. Since in each position of the flap 2 of the legs 51 is flown more strongly than the leg 50, the flow seeks the flap 2 against the force of the spring elements, ie the tension springs 21 and 22 to close.
