Definitions

  • the invention relates to a side channel compressor according to the Preamble of claim 1.
  • Such a compressor is known from DE-B-14 28 251.
  • the run against the Side channel radially extending boundary edges of the interrupter oblique to the axis of rotation of the compressor inclined.
  • the invention has for its object a side channel compressor of the generic type so that no negative effects despite good noise reduction enter the characteristic curve of the compressor.
  • the problem is solved according to the invention by the features specified in the characterizing part of claim 1.
  • the heart-shaped incisions will make a very good one Damping of itself from the number of blades and the speed of the Impeller resulting blade tones reached without this Has repercussions on the characteristic curve of the compressor.
  • An opening angle has proven particularly favorable for the Pointed out heart-shaped incisions of less than 25 °.
  • the housing of the side channel blower consists of two together connectable housing halves, then it is advantageous if the incisions are symmetrical to the axial center of the Breakers are trained. It is then possible to to design both housing halves identically. Moreover the incision sides of the reworked heart-shaped incisions if necessary become.
  • the size of the radius the curves of the heart-shaped incisions equal to half to whole lateral distance of the tip to the respective axial Boundary edge of the breaker corresponds.
  • With 1 is the compressor housing of a side channel compressor designated.
  • a drive motor 2 is flanged to this housing 1, on its shaft 3 that not shown in the drawing Impeller of the compressor is arranged.
  • On the compressor housing 1 is a side channel 4 in a known manner molded. Between the ends of each in the side channel 4 The inlet and outlet opening 5 and 6 of the compressor is a Interrupter 7 is provided, which the suction side and pressure side separates the compressor.
  • the opposite the side channel 4 in the radial direction limiting sides 8 of the breaker 7 each have a heart-shaped Incision 9 on.
  • the suction side and the heart-shaped on the pressure side Notch 9 symmetrical to the axial center 10 of the breaker 7 trained.
  • the radius R of the tip regions 11 of the heart-shaped incisions 9 is slightly smaller than the lateral one Distance B1 of the tip 12 of the heart-shaped incisions 9 to the respective axial boundary edge 13 of the interrupter 7 chosen.
  • the radius R is thus smaller than half the axial width B of the breaker 7.
  • the opening angle ⁇ of the tip 12 of each heart-shaped incision 9 is less than 25 °.
  • FIG 3 shows an off-center Arrangement of the heart-shaped incisions 9 different lateral distances B1 and B2 of the tip 12 to the axial boundary edges 13 of the interrupter 7.
  • the radii R1 and R2 of the tip regions 11 are the same respective lateral distance B1 or B2 selected.
  • the crest areas 11 of each heart-shaped incision 9 in Staggered circumferential direction.
  • Such training the breaker 7 acts like one with respect to the axis of rotation sloping boundary side 8. This takes place the transfer of the conveyor blades aligned parallel to the axis of rotation of the impeller in the breaker area more continuous.
  • the one incision side 15 runs arcuate in this embodiment.
  • the other cut side 16 has a straight course.
