Definitions

  • Due to the adjustability of a flow control element can the relationships between the work flows and the power flow in the fan can be changed so that a desired change in the blower characteristics or characteristic is possible in a simple manner. Even if one Changing the blower characteristics by changing other parameters or components are brought about, so can this advantageously by the at least one adjustable flow guide are supported, and optimal adaptation is possible in a simple manner.
  • the flow guide element is preferably wing-like trained, on the one hand, the lowest possible flow resistance to form and on the other one as possible to be able to have a great influence on the direction of flow.
  • the suction opening is advantageously with a extending into the first suction space, in the manner of a Delivery injector as a ring wall, partial ring wall or Spoiler wall provided trained injector wall, the suction opening and / or the injector wall preferably diagonally to the direction of flow inside the first suction chamber is directed.
  • the one through the intake opening Air flow drawn in from outside leaves the first suction space due to the rotation of the impeller accelerates in radial Direction. Part of this accelerated air flow arrives from the outside as a so-called first working current back into the first suction chamber, the entrance area the rearmost area in front of the Partition is. This first working current flows inside of the first suction chamber past the suction opening.
  • the injector wall is expediently on the inside attached to the corresponding side wall of the housing or molded or integrally connected to this.
  • the suction opening can be varied. There is a small one Intake opening to achieve a steeper pressure-volume characteristic or a large suction opening to achieve this a flattened pressure-volume characteristic is provided. Thanks to the adjustable flow control element a quick and easy adaptation to a changed one Characteristics take place and these are supported.
  • a partition extends from the side wall 24 26 and divided into the interior of the pot-like impeller 10 whose interior into a first suction chamber V1 and one second suction chamber V2, which faces the peripheral wall region 19 is.
  • This partition 26 can according to the beginning indicated prior art from the side wall 24 extend obliquely to the bottom 12 of the impeller 10, wherein in principle also an arrangement parallel to the axis of rotation the impeller 10 is possible.
  • the spoiler-like surrounds Injector wall 34 like a ring, the air intake opening 28 or 36 on opposite to the flow direction End region of this air intake opening 28 or 36.
  • this could also be a tubular or Kick injector wall.
