Definitions

  • the invention relates to a side channel compressor, with a in its housing rotatably arranged impeller, the one with Conveyor vanes have a supporting ring, which a him load-bearing and with a drive shaft connecting hub part axially protrudes at least on one side, which Compressor in the area of the support ring between the Impeller and the housing existing gap sealing Sealing device is provided.
  • Such a side channel blower is through DE-A-22 44 933 known.
  • a band is inserted into an annular groove provided in the housing, that extends against the end face of the support ring.
  • the Band is aligned in the ring groove so that a gap as small as possible between the face of the Tragringes and the protruding from the annular groove end of Band results in the so-called gap losses to keep it as small as possible.
  • the invention has for its object a side channel compressor of the generic type so that the Sealing the gap despite lower manufacturing and Assembly effort is significantly improved.
  • the problem is solved according to the invention in that an axially projecting on the inner circumference of the Part of the support ring adjacent, radially extending Sealing ring by means of a retaining ring against one on the housing provided contact surface is held clamped.
  • a closed Ring shape of the sealing ring enables.
  • the outside diameter of the In terms of production technology, the sealing ring can fit the inside diameter very precisely of the support ring can be adjusted.
  • the attachment the retaining ring is expediently carried out by means of screws.
  • the sealing ring in one in the area formed corner recess on the respective end face of the support ring intervenes.
  • a machined area is thus available.
  • there is an axial support of the sealing ring in the area its outer circumference when the sealing ring here through the prevailing compression pressure due to its elasticity is axially deflected.
  • the Housing halves 1 and 2 enclose one on one in the Drawing not shown drive shaft arranged Impeller 4.
  • the impeller 4 has one on its outer circumference Support ring 5 on which the conveyor blades 6 of the impeller 4th are arranged.
  • the support ring 5 is on one on the Drive shaft plugged and rotatably with this connected hub part 7 arranged.
  • each housing half 1 and 2 is in the radially inside of the support ring 5 at this adjacent area, a sealing arrangement intended.
  • This consists of a plastic sealing ring 8, which by means of screws 9 attached retaining ring 10 against a corresponding on the Provided housing wall of the respective housing half 1 or 2 Contact surface is kept.
  • each end face 11 rotated into which the sealing ring 8 engages.
  • the Sealing ring 8 lies with its outer circumference on the inner circumference of the axially extending wall part of the corner recess 11 on.
  • the corner recess 11 there is a high dimensional accuracy with regard to the diameter of the corner recess 11 before. Since the sealing ring 8 with respect its outer diameter can be manufactured with high accuracy a good sealing effect can be achieved. In this way can over the between the impeller 4 and the existing housing half 1 or 2 existing gap 12 resulting leakage losses can be significantly reduced.
