Definitions

  • the invention relates to a volumetric flow controller, in particular for air conditioning and ventilation systems, with a rotatably mounted inside a flow channel about a transversely oriented to the flow axis pivoting damper, wherein the control damper under the influence of an inflowing the control valve medium against a restoring force generated by a restoring force from the Open position in a closed position is pivotable and is adoptedverschwenkt at decreasing flow through the restoring force back to the open position, and with a the open position of the control flap limiting stop, which changes the flowing in the open position of the control valve volume flow around an axis extending through two bearings axis of rotation rotatably mounted on the flow channel and can be fixed by means of a fixing device in its orientation, wherein at least one bearing point from outside of the flow channel to the change ung the orientation of the stopper is accessible, wherein the pivot axis of the control flap is provided on the stop and wherein the restoring device connected to the stop, in particular attached to the stop.
  • volumetric flow controllers are known in various designs (see, for example, patent document DE-2020043811-U ). They work mechanically automatically, because the flow-related control valve torque is compensated by the restoring force, which is usually generated by a resetting designed as a spring. When changing the flow conditions, the pivot position of the control cap also changes, so that the volume flow is controlled automatically in the flow channel.
  • the object of the invention is to provide a volume flow regulator, which is easier and faster to install and in case of damage, the control valve and / or the stop can be swapped quickly (can).
  • At least one of the accessible from outside the flow channel bearing points of the stop is formed by an inserted from outside the flow channel through a recess bearing element, which is shorter than the diameter of the flow channel and forms only the bearing of the stop on this page ,
  • the stop can be supported by one or by two bearing element elements according to the invention. If only one Inventive bearing element is provided, one of the two bearings need not be accessible from the outside.
