Definitions

  • a swirl generating device having the features of claim 1, wherein according to the underlying idea, a vorschiebbarer in the neck-like inlet of the housing and / or in the suction line, the impeller upstream swirl generator is provided, the housing suction side for connection is formed like a nozzle with the suction line and the swirl generator in the connecting region between the suction line and the housing is arranged and the swirl generator comprises a mounting flange both for radial fixing within the suction line or the housing, as well as for axial fixing between the suction line and housing.
  • the fastening flange has a lip radially on the outside as an assembly aid and for the seal.
  • the swirl generator prefferably has an annular, radially outer region which optionally simultaneously forms the aforementioned fastening flange, with inner guide vanes, and the guide vanes are arranged rigidly, the vanes being adjustable and / or deformable according to a particularly preferred embodiment, so that an adjustment can be made according to the mass throughput.
  • the swirl generator 7 is made of a plastic such as glass-fiber reinforced polyamide, where appropriate - especially if a backflow of hot charge air from the compressor can not be effectively prevented - a metal version is preferred. Due to the high temperatures occurring in the charge air compression, the compressor housing 3 is made of cast aluminum; the charge air intake manifold is made of glass fiber reinforced polyamide.
  • the leading edges 206 and the wings 202 extending in the direction of flow a can be seen.
  • the swirl generator In mounting position, the swirl generator is in the area between suction line and pump or compressor housing (see. FIG. 1 ) are fixed by means of the annular, radially outer region 204, so that the region 204 projecting in the axial direction, such as leading edges 206 and wings 202, for receiving in the intake manifold or in the intake manifold have a reduced diameter.
  • the central region 208 is conically formed on the inflow side, the vane edges 218 are retracted in the flow direction a to a smaller diameter, the terminations are rounded.
