Definitions
- the invention relates to a side channel compressor, according to the Preamble of claim 1.
- Such a side channel compressor is known from EP-A-0 708 248 known.
- this known compressor there is a sealing ring by means of a retaining ring against one on the housing of the Side channel compressor clamped contact surface held.
- the sealing ring extends in the radial direction to the one that carries the blades of the side channel blower Support ring and lies on its inner circumference. To one To achieve good sealing, the sealing ring must be on everyone Place the inner circumference properly. This sets in very precise centric alignment of the sealing ring ahead, what only through a correspondingly high installation effort to achieve.
- the invention has for its object a side channel compressor of the generic type so that the Sealing ring in a simple manner with high alignment accuracy can be assembled.
- the task is solved by the in the license plate of claim 1 specified features.
- the sealing ring only needs in the centering edge for precise alignment to be indented.
- the centering edge itself can be in can be easily produced by a turning process
- Impeller 2 With 1 is a housing half of a side channel compressor housing designated. Two to one full case joined housing halves 1 enclose one a drive shaft, not shown in the drawing Impeller 2.
- the impeller 2 has on its outer circumference a support ring 3 on which the conveyor blades 4 of the Impeller 2 are arranged.
- the support ring 3 is on one the drive shaft plugged in and rotatably connected to it Hub part 5 arranged.
- a sealing arrangement intended On each housing half 1 is in the radially inside the Support ring 3 at this adjacent area, a sealing arrangement intended. This consists of a plastic sealing ring 6, which is fastened by means of screws 7 Retaining ring 8 against a corresponding one on the housing wall the respective housing half 1 provided contact surface is held.
- the central alignment of the sealing ring 6 takes place by means of one provided on the respective housing half 1 Centering edge 10.
- the sealing ring 6 then only needs to be pushed in behind this centering edge 10.
- By the centering edge 10 results in a positive fixation of the sealing ring 6, thereby causing the sealing ring to move away 6 is prevented radially outwards.
- the sealing ring 6 corresponds to the outside diameter of the sealing ring 6 the inner diameter of the Centering edge 10.
- the sealing ring 6 is in the axial direction dimensioned accordingly thick so that it is opposite the centering edge 10 projects axially and engages in the corner recess, being on the axially extending wall portion of the Corner recess 9 abuts and thus between the impeller 2 and seals the respective housing half 1 existing gap 13.
