Definitions

  • the invention relates to a volume flow controller, in particular for air conditioning systems, with one by the action of an inflowing gas against a restoring force and a damping force pivotable throttle valve.
  • volume flow controllers are known from practice and serve to regulate the volume flow within a Air conditioning system such.
  • the throttle valves start to vibrate during control can be elements to dampen these vibrations built-in. These elements usually work through friction, either through direct contact between two Solids or by hydraulic or pneumatic effects, e.g. B. is generated in cylinders.
  • the object of the invention is a volume flow controller to improve such that the vibration behavior of the in the throttle valve located in the volume flow controller improved and the vibrations are as low as possible.
  • a preferred embodiment of the invention is to achieve the damping force corresponding to the pivoting the throttle is deflected by the magnetic field of a magnet-moving metallic damping element intended. It is obvious that the damping element and / or the magnet both inside as well outside a duct section of an air conditioning system can be arranged.
  • the degree of damping depends on the vibration the throttle valve. With strong vibration behavior the throttle valve is damped more. A damping in the rest position takes place in contrast to conventional dampers not instead.
  • the damping element can be a circular disc or a circular segment disc be trained.
  • the damping element can be made of aluminum or copper exist, using other materials can, provided they are electrically conductive.
  • a spring can be provided to achieve the restoring force his.
  • Fig. 1 shows a duct section 1 of an air conditioner in which a throttle valve 3 is pivotally mounted on an axis 2 is.
  • the throttle valve 3 has essentially the shape of the cross section of the channel piece 1.
  • the throttle valve 3 is in the open state parallel to the air flow a while the closed position the throttle valve 3 is perpendicular to the air flow a.
  • a damping element 4 On the throttle valve 3 is on one side, preferably on the downstream side, a damping element 4 is provided, that in the example shown is a circular segment disc is.
  • the damping element 4 has in the illustrated Case on the edge of a metallic area 5, such as. B. Aluminum or copper. But it is also possible that the complete damping element 4 z. B. as aluminum or Is copper, so in this case the metallic area 5 does not apply.
  • a magnet 6 is arranged on one side of the damping element 4. Now becomes the electrically conductive metallic area 5 of the damping element 4, d. H. when the throttle valve vibrates 3, moved by the magnetic field of magnet 6, thus electrical currents in the metallic Area 5 induced. These currents in turn generate one Magnetic field that with the external field of the magnet 6 in Interaction occurs. This results in a damping, whereby the faster the movement, the stronger the d. H. the faster or stronger the vibration of the throttle valve 3 is.
  • a spring 7 is provided to the throttle valve 3 from the closed position to the open position to move. To increase the stability of the channel piece 1, this has Surrounding beads 8, 9 on both sides in the walls.
  • the 2 is a duct section 1 with a throttle valve 3 provided in which the damping element 4 as a disc trained and together with the magnet 6 outside of Channel piece 1 is arranged.
  • the magnet 6 is U-shaped, the magnet 6 with legs 10, 11 the damping element 4 includes.
