Definitions

  • the invention relates to a side channel compressor according to the Preamble of claim 1.
  • Such a side channel blower is through DE-A-22 44 933 known.
  • this known side channel blower is in each one to the level of between the Impeller and the housing existing gap transverse
  • a sealing tape is inserted in the groove of the housing cover.
  • This Sealing tape can be used when installing the side channel blower be brought into position by the impeller itself. In this position, the sealing tape is then applied to different Way, including by an adhesive or sealant fixed.
  • the adhesive or sealant is after alignment of the sealing tape via corresponding externally accessible Breakthroughs made in the groove. Part of the Mass emerge from the groove and engage with the impeller stick, which blocks it and the compressor does not can start. It can also change over time the side channel blower the connection of the adhesive or Loosen the sealing compound from the smooth wall surface of the sealing tape.
  • the invention has for its object a side channel compressor of the generic type so that an impairment of the functionality of the side channel blower largely by a sealing tape attached to the housing is excluded.
  • the task is solved by the in the license plate of claim 1 specified features. As a result of that only in some places of the circumferential groove a solidifying Mass is introduced, there is a risk of blocking the Impeller practically excluded due to too much mass. Due to the positive connection between the mass and the Sealing tape is a permanent holder for the sealing tape given.
  • sealing tape It is also advantageous to drill holes or perforations on the sealing tape to provide, which is at least partially with the Fill the mass and thus for a perfect form fit of the Provide mass with the sealing tape.
  • Can be used as a sealing tape A special advantage is a material strip made of Teflon be provided.
  • This sealing arrangement consists of a sealing tape 8, the in a compared to the base ring 5 of the impeller 2 in the each housing half 1 trained circulation groove 9 inserted is.
  • the sealing tape 8 is held by means of a some places of the circumference of the circumferential groove 9 introduced into this Mass 10.
  • This mass 10 has the property of itself only solidify to a certain extent. However not harden, i.e. the mass shows in the solidified state some elasticity.
  • To easily measure 10 in to be able to introduce the circumferential groove 9 are on the corresponding Make bag-like extensions 11 in the area of Circulation groove 9 provided. The opening side 12 of these extensions 11 lies on the inside of the respective housing half 1. So that the mass 10 can only from here in the Circulation groove 9 are introduced so that an emergence of the Mass 10 from the circulation groove 9 or the bag-like extension 11 is noticed and any escaped mass 10 is eliminated can be.
  • Bores 13 are provided in the sealing tape 8, which are of such a type are arranged in the sealing tape 8 that they when inserted of the sealing tape 8 in the circulation groove 9 each in a bag-like Extension 11 come to rest.
  • the Mass 10 in the sack-like extension 11 penetrates part of the Mass 10 in the holes 13 and at least fills them partially out. This results in a positive connection between the mass 10 and the sealing tape 8, so that this through the Mass 10 is secured in the circulation groove 9.
  • the sealing tape 8 Before assembling the housing half 1 with the impeller 2 the sealing tape 8 is inserted into the circumferential groove 9 and the Mass 10 introduced into the bag-like extensions 11. There the mass 10 is initially still soft, is when assembling the housing halves 1 with the impeller 2 through the sealing tape 8 corresponding to the abutting base ring 5 of the impeller 2 pressed into the circumferential groove 9. The sealing tape 8 is thus full on the base ring 5. By yourself Gradually solidifying mass 10, the sealing tape 8 in held this optimal sealing position.
