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 boundary edges of the interrupter which extend radially with respect to the side channel, are inclined relative to the axis of rotation of the compressor. Noise reduction is achieved by such an inclination of the boundary edges, but the pressure characteristic of the compressor is adversely affected.
  • the invention has for its object to develop a side channel compressor of the generic type so that no negative effects on the characteristic of the compressor occur despite good noise damping.
  • An opening angle for the tip of the heart-shaped incisions of less than 25 o has proven to be particularly favorable.
  • the housing of the side channel compressor consists of two housing halves which can be connected to one another, it is advantageous if the incisions are formed symmetrically to the axial center of the interrupter. It is then possible to design both housing halves identically. Furthermore If necessary, the incision sides of the heart-shaped incisions extending to the tip can be reworked.
  • the size of the radius of the curves of the heart-shaped incisions corresponds to half to the entire lateral distance of the tip from the respective axial boundary edge of the interrupter.
  • a side channel compressor With 1 the compressor housing of a side channel compressor is designated.
  • a drive motor 2 is flanged to this housing 1, on the shaft 3 of which the impeller of the compressor (not shown in the drawing) is arranged.
  • a side channel 4 is formed on the compressor housing 1 in a known manner.
  • An interrupter 7 is provided between the inlet and outlet openings 5 and 6 of the compressor, each opening into the side channel 4, which separates the suction side and the pressure side of the compressor.
  • the heart-shaped incision 9 on the suction side and on the pressure side are formed symmetrically to the axial center 10 of the interrupter 7.
  • the radius R of the tip regions 11 of the heart-shaped incisions 9 is selected to be somewhat smaller than the lateral distance B1 of the tip 12 of the heart-shaped incisions 9 from the respective axial boundary edge 13 of the interrupter 7.
  • the radius R is thus smaller than half the axial width B of the interrupter 7.
  • the opening angle ⁇ of the tip 12 of each heart-shaped incision 9 is less than 25 o .
  • the exemplary embodiment according to FIG. 3 shows an eccentric arrangement of the heart-shaped incisions 9. This results in different lateral distances B1 and B2 of the tip 12 from the axial boundary edges 13 of the breaker 7.
  • the radii R1 and R2 of the tip regions 11 are equal to the respective lateral distance B1 or B2 selected.
  • the crest areas 11 of each heart-shaped incision 9 are offset from one another in the circumferential direction.
  • Such a configuration of the interrupter 7 acts like a limiting side 8 which is inclined with respect to the axis of rotation.
  • the transfer blades of the impeller which are aligned parallel to the axis of rotation, thus pass into the interrupter region even more continuously.
  • a radius R1 that is smaller than the lateral distance B1 is selected for the one crest region 11. This results in a rectilinear portion 14 of the boundary side 8 at the transition from the top region to the boundary edge 13.
  • the one incision side 15 is arched in this embodiment.
  • the other incision side 16 has a straight course.
